tests/test_podcast_search.py (2)
133-139: Consider importing _MAX_FILTER_VALUE_LENGTH for the truncation assertion.

The test hardcodes 500 as the expected truncation length. If the constant changes in the source module, this test would fail silently or pass incorrectly.
♻️ Suggested improvement
 def test_escape_truncates_long_values(self):
     """Test that long values are truncated."""

     result = escape_filter_value(long_value)
-    assert len(result) == 500
+    assert len(result) == _MAX_FILTER_VALUE_LENGTH
420-440: Consider narrowing the exception type or adding a comment explaining the intent.

The broad except Exception catch (lines 431 and 461) is flagged by static analysis. While catching all exceptions is a common pattern in thread-safety tests to ensure failures are reported rather than silently ignored, adding a comment clarifies the intent.
♻️ Optional: Add clarifying comment

🔇 Additional comments (6)

tests/test_podcast_search.py (6)

13-73: LGTM!

Comprehensive tests for sanitize_query covering all documented behaviors: whitespace handling, control character removal with newline/tab preservation, truncation at 2000 characters, and injection pattern detection. The tests correctly verify that injection patterns are logged but not blocked.

142-222: LGTM!

Well-structured tests for citation storage with proper cleanup patterns. The copy semantics test (lines 175-197) correctly verifies that get_podcast_citations returns a copy rather than a reference to the stored data.

224-326: LGTM!

Thorough test coverage for the podcast filter storage including the mutual exclusivity constraint between podcast_name and podcast_list. The use of pytest.raises with match pattern (line 305) is the idiomatic approach.

328-406: LGTM - previous review concerns have been addressed.

The cleanup tests now correctly:

Patch time.time in the target module (podcast_search_module.time)

Include explicit assertions verifying cleanup behavior (lines 364 and 401)

Use proper cleanup in finally blocks

The two-phase patching approach (old timestamp for initial set, current time for cleanup trigger) effectively tests the TTL-based cleanup mechanism.

473-494: LGTM!

Good practice to maintain test coverage for deprecated functions to ensure backwards compatibility. The test correctly verifies that get_latest_podcast_citations delegates to the _default session.

497-522: LGTM!

The extended injection pattern tests complement test_sanitize_query_detects_injection_patterns by including additional variations (uppercase patterns, bracket syntax like <system> and [system]). The main block follows standard pytest conventions.

tests/test_gemini_search.py (2)
35-42: Minor: Unused variable in test.

The manager variable on line 39 is assigned but never used. While this doesn't affect test correctness, you could remove the assignment for clarity.
🔎 Proposed fix

465-487: Minor: Missing assertion in auto-title test.

The test at line 481 assigns the response but never checks it. Consider adding assertions to verify the streaming response is returned correctly.
🔎 Proposed fix
         response = client.post(
             "/api/conversations/conv-1/messages",

tests/test_email_service.py (1)
54-69: Minor: Unused variable in initialization tests.

The service variable is assigned but never used in these tests. This is acceptable but could be removed for clarity if you prefer.

tests/test_auth.py (1)
219-229: Consider using pytest-asyncio for cleaner async test patterns.

The pattern asyncio.get_event_loop().run_until_complete() is deprecated in Python 3.10+. Consider using pytest-asyncio with @pytest.mark.asyncio decorator for cleaner async testing:
@pytest.mark.asyncio
async def test_get_current_user_success(self, mock_config, mock_request):
    user_data = {"sub": "user-123", "email": "test@example.com", "name": "Test"}
    token = create_access_token(user_data, mock_config)
    result = await get_current_user(mock_request, podcast_rag_session=token)
    assert result["sub"] == "user-123"
This pattern is repeated throughout the async dependency tests.
tests/test_mcp_server.py (1)

82-107: Tests simulate tool logic rather than testing actual implementation.

These tests (lines 82-107, and similar patterns throughout) recreate the tool's logic inline rather than calling the actual MCP tool functions. This approach tests the mocked behavior but doesn't verify the real implementation matches. Consider whether integration-style tests that invoke the actual tool functions would provide more confidence.
tests/test_email_digest.py (1)
88-106: Time-sensitive test may be flaky.

The test test_get_pending_count relies on datetime.now(UTC).hour matching between test setup and execution. In rare cases near hour boundaries, this could cause intermittent failures.
🔎 Consider freezing time for deterministic tests
+from unittest.mock import patch
+
     def test_get_pending_count(self, worker, mock_repository):
         """Test getting pending count filters by delivery time."""
-        mock_user1 = Mock()

+            mock_user1.email_digest_hour = 10  # Matches fixed hour
tests/test_orchestrator.py (2)
158-198: Unused worker variable assignments are intentional but could be cleaner.

The static analyzer flags unused worker variables, but the tests are verifying that the worker instance is created (checking orchestrator._sync_worker is not None). While functional, the pattern could be slightly cleaner.
🔎 Optional: Use underscore prefix for unused returns
     @patch("src.workflow.orchestrator.SyncWorker", create=True)
     def test_get_sync_worker_creates_worker(self, mock_worker_class, orchestrator):
         """Test that _get_sync_worker creates worker on first call."""
         with patch("src.workflow.workers.sync.SyncWorker", mock_worker_class):
-            worker = orchestrator._get_sync_worker()
+            _ = orchestrator._get_sync_worker()
 
             assert orchestrator._sync_worker is not None
542-562: Remove unused result variable.

The result variable at line 558 is assigned but never used. Since the test verifies behavior through mock assertions, the variable can be removed.
🔎 Proposed fix
         orchestrator._running = True
 
-        result = orchestrator._pipeline_iteration()
+        orchestrator._pipeline_iteration()
 
         assert orchestrator._stats.transcription_permanent_failures == 1
         mock_repository.mark_permanently_failed.assert_called_once()
tests/test_feed_sync.py (1)
175-200: Remove unused result variable and verify metadata update arguments.

The result variable is assigned but never used. Additionally, the test only verifies that update_podcast was called but doesn't verify it was called with the correct arguments.
🔎 Proposed improvements
         sync_service.feed_parser.parse_url = Mock(return_value=mock_parsed)
 
-        result = sync_service.sync_podcast("pod-1")

+        assert calls[-1][0][0] == "pod-1"  # First positional arg is podcast_id
tests/test_scheduler.py (1)
78-79: Consider moving import logging to module level.

The logging import is repeated inside multiple test functions. Moving it to the top of the file with other imports would be more conventional.
🔎 Proposed fix

At the top of the file:
 import pytest
 from unittest.mock import Mock, patch, MagicMock
+import logging

 from src.scheduler import run_pipeline
Then remove the in-function imports:
-            import logging
             with caplog.at_level(logging.INFO):
Also applies to: 111-112, 136-137
tests/test_post_processor.py (1)
301-316: Avoid time.sleep() in tests - potential flakiness.

Using time.sleep(0.1) introduces non-determinism and can cause flaky tests, especially on slower CI runners. Since the test already patches _process_episode_chain, you could either:

Wait on the job future directly

Assert immediately after submit since the mock prevents actual async work
🔎 Proposed fix
     def test_submit_adds_to_pending(self, processor, mock_repository):
         """Test submit adds job to pending."""
         mock_repository.get_episode.return_value = None

         processor.start()

         with patch.object(processor, "_process_episode_chain"):
             processor.submit("ep-123")

-            # Give the executor a moment to register the job
-            import time
-            time.sleep(0.1)
+            # Immediately verify submit was called - the mock prevents actual execution
+            # The job is added synchronously before the future starts

         # The job should have been submitted
         # (it may complete quickly, so we just verify no errors)
         processor.stop()
tests/test_podcast_routes.py (1)
511-534: Consider prefixing unused mock_repo with underscore.

The mock_repo variable is unpacked but not used in this test. Per coding conventions and static analysis, prefix it with _ to indicate it's intentionally unused.
🔎 Proposed fix
     @patch("src.web.podcast_routes.FeedSyncService")
     def test_add_new_podcast_success(self, mock_sync_class, authenticated_client):
         """Test successfully adding a new podcast."""
-        client, mock_repo = authenticated_client

🔇 Additional comments (82)

tests/test_web_app.py (3)

516-566: LGTM! Comprehensive tests for truncate_text helper.

The test suite covers all important edge cases including short text, exact length, long text with ellipsis, word boundary truncation, and None/empty string handling. The tests are well-structured and follow pytest conventions.

568-612: LGTM! Good coverage for async_iterate helper.

The tests cover empty iterators, populated iterators, and string items. The use of asyncio.get_event_loop().run_until_complete() is appropriate for testing async generators.

614-732: LGTM! Thorough tests for podcast info extraction.

The test suite covers all critical paths:

No candidates scenario

Missing grounding metadata

Empty grounding chunks

Valid chunks with proper repository lookup

Deduplication logic

The mock setup is comprehensive and properly simulates the Gemini API response structure.

tests/test_gemini_search.py (4)

23-34: LGTM! Dry run initialization test is correct.

The test properly validates that in dry run mode, model validation is skipped. The unused mock_genai variable flagged by the linter is acceptable here as it's needed to patch the import.

104-116: LGTM! Dry run search test is clean.

The test properly validates that dry run mode returns empty documents/metadatas without making API calls.

117-155: LGTM! Search with results test is comprehensive.

The test properly mocks the Gemini API response structure including candidates, grounding metadata, and file_search_citations. Good coverage of the happy path.

156-182: LGTM! No grounding metadata test is well-structured.

The test properly uses Mock(spec=[]) to create a mock without the grounding_metadata attribute, correctly simulating the edge case.

tests/test_chat_routes.py (3)

52-100: LGTM! List conversations tests are comprehensive.

The tests cover success, empty state, and pagination scenarios. Good use of mock repository with proper assertions on called methods.

105-196: LGTM! Create conversation tests cover all validation paths.

The tests properly validate:

Different scope types (all, podcast, episode)

Missing required IDs for scoped conversations

Non-existent podcast/episode handling

Successful creation with all scenarios

243-313: LGTM! Conversation retrieval tests cover important edge cases.

The tests validate conversation retrieval with messages, citations, and proper ownership checks. The mock setup for citations is well-structured.

tests/test_email_service.py (3)

9-31: LGTM! Email redaction tests are thorough.

The tests cover valid emails, subdomains, and invalid inputs (no @ symbol, empty string). This properly validates PII protection logic.

107-153: LGTM! Email sending tests are comprehensive.

The tests cover success, failure, text content handling, and proper error handling. The mock assertions verify API calls are made correctly.

154-167: LGTM! From address formatting test is valuable.

This test ensures the from address is built correctly with both name and email in the expected format.

tests/test_feed_parser.py (7)

256-257: LGTM! Proper cleanup of empty string test.

The change correctly validates that empty strings return None, consistent with the implementation's behavior.

259-326: LGTM! URL parsing tests are thorough.

The tests cover:

Successful parsing

HTTP errors with proper exception handling

Invalid feed content

Bozo warnings (malformed but parseable feeds)

Good use of mocking to isolate the HTTP layer.

328-345: LGTM! Parser initialization tests validate configuration.

The tests verify that custom user_agent, retry_attempts, and timeout values are properly stored. Clean and straightforward.

369-422: LGTM! Metadata parsing tests cover TTL edge cases.

The tests validate lastBuildDate and TTL parsing, including invalid TTL values that should return None. Good edge case coverage.

424-517: LGTM! Enclosure extraction tests are comprehensive.

The tests cover multiple extraction paths:

Audio detection by file extension (mp3, m4a, ogg, opus, wav, aac)

Media:content elements

Link elements with rel=enclosure

The tests properly use the internal _extract_enclosure method to test specific scenarios.

519-558: LGTM! Image extraction tests validate fallback behavior.

The tests cover both iTunes image tags and channel image fallbacks. Good coverage of different feed formats.

560-656: LGTM! Edge case tests are thorough.

The final test classes cover important edge cases:

Published date parsing from raw strings

Unrecognized explicit values returning None

Invalid duration formats

Episodes without titles using fallbacks

Invalid season numbers

Invalid enclosure lengths

These tests ensure robust handling of malformed or incomplete feed data.

tests/test_auth.py (2)

176-192: Singleton reset pattern is acceptable but fragile.

Directly manipulating src.web.auth._oauth = None to reset the singleton works for testing but couples tests to implementation details. This is acceptable for now but consider adding a dedicated reset function in the module if this pattern grows.

1-97: Good test coverage for token creation and verification.

The test suite thoroughly covers:

Token creation with valid data, expiration, and embedded user data

Security validations (missing secret, empty secret, none algorithm rejection)

Token verification including invalid tokens, wrong secrets, and expired tokens

The hardcoded secrets in test fixtures (flagged by Ruff S105) are expected and appropriate for testing purposes.

tests/test_admin_routes.py (3)

30-47: Good fixture setup for admin route testing.

The app fixture properly overrides get_current_admin dependency and sets up repository state. The raise_server_exceptions=False in TestClient is appropriate for testing error responses.

175-183: Unused mock_repository argument is intentional here.

The mock_repository fixture is included in the signature to ensure it's injected into the app fixture chain, but the test intentionally doesn't make repository calls because the endpoint rejects self-demotion before reaching the repository layer. The Ruff ARG002 warning is a false positive in this context.

353-376: Good enum and filter map validation.

Testing that all expected filter types exist and that FILTER_MAP contains entries for all enum values helps catch configuration drift.

tests/test_prompt_manager.py (3)

11-43: Comprehensive placeholder extraction tests.

Good coverage of _extract_placeholders including $name, ${name}, multiple placeholders, deduplication, and underscored identifiers.

45-135: Well-structured PromptManager tests.

The test fixtures properly set up temporary directories with test templates. Tests cover:

Template loading and placeholder extraction

Simple and complex prompt building

Error handling for missing templates and placeholders

Extra kwargs being safely ignored

Good use of print_results=False to avoid log noise during tests.

137-178: Good edge case coverage.

Tests properly verify behavior when:

Prompts directory doesn't exist (graceful degradation)

Directory is empty (no templates loaded)

Non-.txt files are ignored

These edge cases ensure robustness of the PromptManager initialization.

tests/test_argparse_shared.py (1)

1-203: Comprehensive argparse helper tests.

Excellent test coverage for all argument helper functions:

Tests both short (-e, -d, -l, etc.) and long forms

Verifies default values

Confirms required arguments raise SystemExit when missing

Combined test validates multiple helpers work together

The test structure is clean and follows pytest best practices.

tests/test_downloader.py (4)

13-52: Good DownloadResult dataclass tests.

Tests properly verify:

Success and failure result creation

Default values for optional fields

All fields are accessible and correctly typed

269-284: DownloadResult equality tests verify dataclass behavior.

Testing equality comparison ensures the dataclass @dataclass decorator provides expected comparison semantics.

386-417: The download_dir argument is used indirectly via fixture chain.

The Ruff ARG002 warning on line 386 is a false positive. The download_dir fixture creates the directory that downloader fixture depends on. While not directly referenced in the test body, it's required for the test setup. The same applies to lines 448 and 472.

588-663: Thorough MIME type handling tests.

Good coverage of various audio MIME types (aac, opus, wav, m4a) ensuring correct file extensions are generated. The URL-encoded filename test verifies proper handling of encoded characters in URLs.

tests/test_workers.py (6)

1-21: LGTM! Well-structured test module with comprehensive coverage.

The imports and module structure are clean. The test file mirrors the source structure and covers all major worker types as per the coding guidelines.

27-79: Thorough WorkerResult tests with good edge case coverage.

The tests properly validate the dataclass behavior including default values, arithmetic operations, and importantly the errors list independence test (lines 71-79) which verifies that the field(default_factory=list) pattern works correctly to avoid shared mutable state.

86-155: WorkerInterface tests correctly validate logging behavior.

The concrete TestWorker implementations within each test method properly implement the abstract interface. The unused limit parameter (flagged by static analysis) is intentional as it's part of the abstract interface contract.

522-584: RateLimiter thread-safety test is well-designed.

The test at lines 567-584 properly validates thread-safety by spawning multiple threads and verifying all acquires succeed when within limits. The use of a shared list for tracking is appropriate for this concurrency test.

967-989: Good test for CPU compute type fallback.

This test properly validates that when running on CPU with float16 configured, the worker switches to int8 (which is supported on CPU). This aligns with the learning about using fast Whisper for transcription.

203-221: Manual verification required: cannot access repository or implementation code.

The review comment suggests that _cleanup_episode should be tested for file deletion behavior, but I cannot verify this claim without access to the actual implementation. To properly assess this suggestion, I need to see:

The CleanupWorker._cleanup_episode() method implementation

Whether it actually performs file deletion as part of its logic

Please provide the implementation code so the review comment can be properly verified.

tests/test_user_routes.py (5)

1-16: Well-organized test module for user routes.

Clean imports and proper structure following pytest conventions. The imports correctly bring in the components under test.

18-78: Comprehensive validation tests.

Good coverage of timezone validation, hour boundary validation (0-23), and partial request handling. The boundary tests at lines 72-77 correctly verify that both 0 and 23 are valid hours.

122-141: App fixture correctly overrides authentication dependency.

The dependency override pattern at line 132 properly bypasses authentication for testing. Using raise_server_exceptions=False in TestClient allows testing error responses.

328-467: Thorough send-digest endpoint tests.

Good coverage of all scenarios: success, user not found, email not configured (503), no episodes, email failure (500), and pluralization. The test at lines 461-467 properly verifies plural handling ("3 episodes").

232-244: Verify the "no changes" behavior in production code.

The test expects update_user to not be called when an empty JSON body is sent. Ensure the production code in src/web/user_routes.py (specifically the update_user_settings function) actually implements this optimization by checking for empty updates before invoking the database update operation.

tests/test_email_digest.py (4)

1-9: Clean imports with proper UTC usage.

Using datetime.UTC (Python 3.11+) instead of timezone.utc is a modern choice. Ensure the project's minimum Python version supports this.

134-150: Good test for default hour fallback.

The test properly mocks datetime to ensure the default hour (8 AM) is matched. This pattern should be applied to other time-sensitive tests for consistency.

204-239: Comprehensive batch processing test.

The test verifies the complete flow: email service configuration check, user filtering, episode retrieval, email sending, and marking digest as sent. The assertion at line 238 correctly verifies the user ID is passed to mark_email_digest_sent.

463-475: Good test for episode limit enforcement.

This test verifies that the worker limits episodes to 20 per digest, which is an important business rule to prevent overly long emails.

tests/test_description_indexing.py (5)

1-8: Well-structured test imports.

Clean imports that properly reference the worker under test and the base WorkerResult class.

74-97: Good test for successful indexing flow.

The test properly verifies that upload_description_document is called with the correct arguments (podcast_name and description). The return value verification ensures the tuple unpacking works correctly.

98-118: Empty description handling aligns with production code.

Looking at the production code snippet (lines 54-56 in description_indexing.py), the check is if not podcast.description which handles both None and empty string "". Both tests correctly verify this behavior.

225-255: Excellent test for call ordering verification.

The test at lines 225-255 uses a clever callback pattern to verify that mark_description_indexing_started is called before mark_description_indexing_complete. This validates an important invariant in the production code.

277-283: Verify limit is passed through to repository.

Good test that verifies the limit parameter is respected. This ensures proper pagination behavior.

tests/test_orchestrator.py (3)

14-65: Good PipelineStats tests.

The tests properly validate duration calculations for both running and stopped states, and verify counter increments work correctly.

669-678: Good resilience test for status reporting.

The test verifies that get_status handles repository errors gracefully by returning -1 for affected fields. This is important for observability - the status endpoint should not fail even if the database is temporarily unavailable.

707-761: Comprehensive shutdown tests.

Good coverage of shutdown behavior including:

Setting stopped_at timestamp

Waiting for email digest futures

Handling email digest errors gracefully

Shutting down background executor

Stopping post-processor

Unloading transcription model

tests/test_cli_commands.py (6)

1-19: Clean imports for CLI testing.

Proper imports of both the command functions and the test utilities. The structure follows the coding guidelines.

21-94: Comprehensive parser tests.

Excellent coverage of all subcommand argument parsing including optional flags, positional arguments, and argument combinations. Each subcommand is properly tested.

96-123: Main function routing tests are well-structured.

The test at line 99 correctly expects exit code 1 when no command is given. The capsys fixture is technically unused but kept for potential debugging - this is acceptable.

138-157: Mock OPML file creation is a good pattern.

Using tmp_path to create a real OPML file for testing is better than mocking file reads, as it tests the actual file parsing logic.

352-378: Good async mode test.

The test properly mocks asyncio.run to test the async download path without actually running async code. This verifies the conditional logic works correctly.

575-660: Pipeline tests cover post-processing stats.

Good tests for both basic pipeline execution and with post-processing stats. The assertions verify the output formatting is correct.

tests/test_feed_sync.py (3)

1-8: Clean test module setup.

Proper imports for testing the FeedSyncService with mock support.

43-65: Good error path coverage.

Tests properly cover the "podcast not found" and "feed parsing error" scenarios, verifying the error messages are correctly propagated in the result dictionary.

76-123: Comprehensive sync_all_podcasts tests.

Good use of patch.object to mock sync_podcast within the same instance. The tests cover success, partial failure, and aggregation of results.

tests/test_scheduler.py (5)

1-9: LGTM!

Imports are appropriate for the test module, correctly importing the necessary fixtures and classes from the source modules.

14-35: LGTM!

Fixtures are well-structured and provide appropriate mock objects for testing the scheduler. The mock configurations mirror the expected attributes used by the actual pipeline.

37-60: LGTM!

The test correctly verifies that run_pipeline creates the PipelineOrchestrator with the expected constructor arguments and calls run() once.

85-117: LGTM!

Good test coverage for post-processing stats logging. The test properly creates a PostProcessingStats object with various counter values and verifies the expected log output format.

119-141: LGTM!

Correctly tests the absence of post-processing log lines when post_processing is None.

tests/test_post_processor.py (7)

16-31: LGTM!

Good tests for the PostProcessingJob dataclass, covering both default and explicit future assignment.

99-118: LGTM!

Excellent thread-safety test. It properly validates that the lock-protected increment methods work correctly under concurrent access with 10 threads each doing 100 increments.

440-445: LGTM!

Good test for handling missing episodes - verifies the chain exits gracefully without raising exceptions.

477-491: LGTM!

Comprehensive test for the cleanup stage, properly setting up all required status conditions for cleanup to trigger.

523-546: LGTM!

Good test for the success path in metadata processing, verifying stats increment and repository calls.

548-577: LGTM!

Good coverage of both retry and permanent failure paths for metadata processing, correctly testing the boundary at max_retries.

737-757: LGTM!

Good tests for the job completion callback, verifying both normal completion and exception handling paths.

tests/test_podcast_routes.py (5)

488-509: LGTM!

Good test for the "already subscribed" scenario, properly verifying that no duplicate subscription attempt is made.

632-663: LGTM!

Well-structured async client mocking pattern for testing the search endpoint. The mock setup properly handles the async context manager pattern.

736-772: LGTM!

Good error handling tests for timeout and HTTP errors. Correctly verifies appropriate status codes (504 for timeout, 502 for upstream errors).

820-875: LGTM!

Good coverage of OPML import scenarios including empty OPML and new podcast addition paths.

907-984: LGTM!

Comprehensive error handling tests for OPML import, covering parse errors, sync failures, and database exceptions. Good validation that failures are captured in the response rather than causing 500 errors.

⚠️ Potential issue | 🟡 Minor

Test does not verify anything meaningful.

test_get_rag_context_decorator_exists only patches classes and passes without assertions. Either remove this test or add meaningful verification that the tool decorator is properly defined.

In tests/test_mcp_server.py around lines 59 to 64, the test currently only patches classes and does no assertions; replace or update it so it actually verifies the tool decorator: import src.mcp_server (without patching away the module), retrieve getattr(src.mcp_server, "get_rag_context", None) and assert it is not None and callable, and additionally assert it has a decorator signature (for example that getattr(get_rag_context, "__wrapped__", None) is not None) to confirm it was decorated; alternatively remove the test entirely if you prefer not to check decorator presence.

550-566: Consider increasing sleep duration for flaky test potential.

The token replenishment test uses time.sleep(0.2) with a 1-second time window. While this should work, timing-based tests can be flaky in CI environments under load.

11-27: Unused mock_search_manager parameter due to decorator order.

The @patch decorators are applied bottom-up, so mock_search_manager is passed first but not used in test_main_initializes_server. This is a minor issue but can be cleaned up.

tests/test_auth_routes.py (2)

13-47: Well-structured test fixtures.

The fixtures properly mock configuration and repository dependencies, following pytest best practices. The mock_config provides all required OAuth and JWT settings for testing auth flows.

290-346: TestMeRoute tests are now complete and properly implemented.

The previous review flagged incomplete tests in this class. The current implementation correctly:

Imports get_current_user from the source module

Uses app.dependency_overrides to inject the mock user

Makes actual HTTP requests via TestClient

Asserts on response status and JSON payload

Cleans up dependency overrides after each test

This aligns with the pattern shown in the relevant code snippet from src/tests/test_user_routes.py.

tests/test_workers.py (2)

683-696: MP3 tag reading test now properly tests actual implementation.

The previous review flagged that the test was patching _read_mp3_tags and then calling it, effectively testing the mock. The current implementation correctly:

Creates an actual dummy file using tmp_path fixture

Calls the real _read_mp3_tags method with that file path

Verifies the return type is a dictionary

This properly exercises the method's behavior with invalid MP3 content (graceful fallback to empty dict).

967-989: Good test for CPU compute type switching.

This test verifies that when WHISPER_DEVICE is "cpu" and WHISPER_COMPUTE_TYPE is "float16", the worker correctly switches to "int8" compute type. This is important behavior for CPU-based transcription performance.

tests/test_mcp_server.py (1)

59-64: Test now properly verifies module entry point.

The previous review flagged test_get_rag_context_decorator_exists as empty. This has been replaced with test_mcp_server_module_has_main which properly verifies the module has a callable main entry point.

tests/test_feed_sync.py (1)

138-151: Assertion strengthened from previous review.

The previous review flagged the weak or-based assertion. This has been fixed with explicit checks:

result["podcast_id"] == "existing-id"

result["title"] == "Existing Podcast"

"already exists" in result["error"]

This properly validates the production behavior documented in the relevant code snippet from src/podcast/feed_sync.py.

tests/test_downloader.py (3)

1-9: Imports are clean.

The previous review flagged an unused dataclass import. The current imports only include what's necessary: pytest, os, datetime, Path, Mock/patch/MagicMock, and the source modules.

385-416: download_dir fixture parameter provides necessary setup.

The static analysis flags download_dir as unused (ARG002), but the fixture is required to ensure the download directory exists before the test runs. The fixture's side effect (directory creation) is the important part, not the variable value itself. This pattern is acceptable in pytest.

54-78: Comprehensive downloader initialization tests.

Good coverage of EpisodeDownloader initialization including directory creation, default values, custom user agent, and progress callback. The fixture pattern properly isolates tests using tmp_path.

tests/test_podcast_routes.py (2)

774-794: Limit clamping test now properly mocks the iTunes API.

The previous review flagged the weak assertion assert response.status_code in [200, 500, 502]. The test now:

Properly mocks httpx.AsyncClient with async context manager support

Returns a valid mock response

Asserts status code is 200

Verifies the API call was made

This properly tests the endpoint's handling of the limit parameter without relying on external services.

488-510: Good test for already-subscribed scenario.

This test properly verifies that when a user is already subscribed to a podcast:

The response message is "Already subscribed"

The episode count reflects existing episodes

subscribe_user_to_podcast is NOT called again

This prevents duplicate subscription attempts.

Add tests for: - argparse_shared module (full coverage) - scheduler module (full coverage) - gemini_search module (comprehensive search tests) - CLI podcast_commands module (parser and command tests) - MCP server module (main function and tool tests) - description_indexing worker (full coverage) - email_digest worker (near full coverage) - web auth module (JWT token and OAuth tests) - email_service module (full coverage with Resend) This is an incremental step toward 95% coverage target.

Auth routes tests (14 tests): - Login endpoint with missing OAuth config scenarios - OAuth callback success for existing/new users - Callback error handling (OAuth error, missing userinfo, etc.) - Cookie domain handling - Logout redirect User routes tests (28 tests): - validate_timezone function - UpdateSettingsRequest validation (timezone, hour boundaries) - GET/PATCH /api/user/settings endpoints - GET /api/user/timezones endpoint - Email preview with episodes, fallback, and empty cases - Send digest now with success, failures, and edge cases

…rage) - List conversations with pagination - Create conversation with scope validation (all, subscriptions, podcast, episode) - Get conversation with ownership verification - Get conversation with messages and citations - Update conversation title - Delete conversation - Send message with ownership verification - Auto-title generation on first message

tests/test_prompt_manager.py (3)

11-42: Good coverage of placeholder extraction patterns.

Tests cover both $identifier and ${identifier} syntaxes, multiple placeholders, deduplication, and underscores. Consider adding a test for escaped $$ (which should be ignored per the source implementation) for completeness.

45-134: Well-structured test suite for PromptManager.

Good use of pytest fixtures with proper dependency chaining (mock_config depends on prompts_dir). Tests comprehensively cover template loading, placeholder extraction, prompt building, and error paths for missing templates and placeholders. The partial string matching for error assertions is appropriately flexible.

137-178: Solid edge case coverage.

Tests appropriately verify graceful handling of missing directories, empty directories, and non-.txt files. The inline config creation in each test is suitable for these isolated edge case scenarios.

tests/test_auth.py (1)

1-486: Excellent comprehensive test coverage for authentication module.

This test suite provides thorough coverage of token creation, verification, OAuth initialization, and user/admin retrieval flows with appropriate success and error path testing. The static analysis warnings about hardcoded passwords are false positives—these are intentionally simple test values in fixtures, not production secrets.

tests/test_feed_parser.py (1)

259-656: Comprehensive feed parser test coverage with excellent edge case handling.

The new test classes provide thorough coverage of:

URL parsing with HTTP errors, invalid feeds, and bozo warnings

Parser initialization with custom options

Metadata parsing (categories, TTL, lastBuildDate)

Enclosure extraction from various sources (media:content, links)

Image extraction with fallbacks

Published date and explicit flag parsing

Duration and episode metadata edge cases

The tests appropriately use mocks to isolate the parser and cover both success and error paths.

tests/test_workers.py (1)

1-989: Comprehensive worker test suite with excellent coverage.

This test module provides thorough coverage of all workflow workers, including:

Base classes (WorkerResult, WorkerInterface) with proper data structure verification

All concrete workers (Cleanup, Sync, Download, Metadata, Transcription) with success/failure paths

Utilities (RateLimiter with thread-safety, MergedMetadata)

Edge cases and error handling throughout

The test at lines 683-691 properly addresses the past review feedback by testing with a real file. The static analysis warnings are false positives (unused abstract method parameters, test-only temp paths).

tests/test_mcp_server.py (1)

1-451: Strong MCP server test coverage with good error handling.

The test suite provides comprehensive coverage of MCP server functionality including initialization, tool functions, integration scenarios, and logging. Past review feedback has been properly addressed. The only minor issues are two unused variable assignments in error path tests (flagged separately).

tests/test_description_indexing.py (1)

1-283: Excellent comprehensive test coverage for description indexing worker.

This test suite provides thorough coverage of the DescriptionIndexingWorker including:

Lazy initialization and caching of GeminiFileSearchManager

Successful indexing with proper manager interaction

Error handling for missing/empty descriptions

Batch processing scenarios (empty, success, partial failure, complete failure)

Ordering guarantees (mark_started before mark_complete)

Proper error propagation and failure tracking

Limit parameter respect

The tests use appropriate mocking patterns and verify both success and error paths comprehensively.

tests/test_admin_routes.py (1)

1-487: Excellent test coverage for admin routes.

This test suite provides comprehensive coverage of all admin endpoints including stats, user management, episode listing, and retry functionality. The tests properly verify response structures, status codes, error messages, and edge cases like pagination, missing relationships, and authorization checks.

tests/test_podcast_routes.py (1)

1-995: Comprehensive test coverage for podcast routes.

This test suite provides excellent coverage of podcast management functionality including:

URL validation and normalization (feed:// to https://)

Adding podcasts (new, existing, already subscribed)

Search with subscription status, error handling, and limit clamping

OPML import with various success and failure scenarios

The tests properly mock external dependencies (FeedSyncService, httpx.AsyncClient, OPMLParser) and verify both success and error paths.

tests/test_chat_routes.py (1)

1-487: Excellent test coverage for chat routes.

This test suite provides comprehensive coverage of conversation management and messaging functionality:

Conversation CRUD operations with proper authorization checks

Scope-based conversation creation (all/podcast/episode)

Message handling with streaming responses and auto-title generation

Proper handling of citations in messages

The tests properly mock dependencies and verify both success and error scenarios including ownership validation.

tests/test_orchestrator.py (1)

1-761: Outstanding test coverage for workflow orchestrator.

This test suite provides exceptionally comprehensive coverage of the PipelineOrchestrator, including:

Statistics tracking and duration calculations

Worker lazy-loading and lifecycle management

Signal handling for graceful shutdown

Sync, download, and email digest workflows

Pipeline iteration with transcription success/failure handling

Post-processing integration

Status reporting with error handling

Complete shutdown sequence

The tests properly mock all dependencies and verify complex orchestration logic across multiple components.

tests/test_auth_routes.py (1)

1-346: Excellent test coverage for authentication routes.

This test suite provides comprehensive coverage of the OAuth authentication flow including:

Login endpoint with configuration validation

Callback endpoint with user creation, error handling, and cookie management

Logout endpoint with proper redirect and cookie cleanup

Me endpoint with user info and admin status retrieval

The tests properly mock OAuth dependencies and verify both success and error scenarios. The TestMeRoute tests are now complete with proper assertions, addressing previous review feedback.

tests/test_cli_commands.py (4)

21-94: LGTM! Comprehensive parser testing.

The parser tests effectively validate all subcommands and their arguments, ensuring proper routing and argument extraction.

125-183: LGTM! Thorough OPML import testing.

Tests cover both success and dry-run scenarios with appropriate mocking and output verification.

185-244: LGTM! Complete add_podcast testing.

Tests cover both success and error paths with proper exit code verification.

285-660: LGTM! Comprehensive test coverage for remaining CLI commands.

The remaining test classes provide thorough coverage:

Feed synchronization (single and all podcasts)

Episode downloads (sync and async modes)

Podcast listing (empty and populated)

Status reporting (overall and per-podcast)

Audio cleanup (dry-run and actual)

Pipeline execution (with and without post-processing stats)

All tests use appropriate mocking, output verification, and edge case handling.

tests/test_scheduler.py (1)

1-141: LGTM! Excellent test coverage for run_pipeline.

This test suite thoroughly validates the run_pipeline function:

Verifies proper orchestrator construction and invocation

Tests logging of basic pipeline statistics

Tests conditional logging of post-processing stats

Covers both presence and absence of post-processing data

The tests use appropriate mocking strategies and caplog assertions to verify behavior without external dependencies.

tests/test_cli_commands.py

Resolve conflicts: - Keep test classes in test_feed_parser.py - Restore missing imports (AsyncMock, MagicMock, patch) in test_podcast_routes.py All 918 tests passing.

In @tests/test_podcast_routes.py:
- Around line 788-790: Replace the hardcoded path in the test by using the
pytest tmp_path fixture: update the test function signature to accept tmp_path,
create a directory under tmp_path (e.g., tmp_path / "podcasts"), and set
mock_config.PODCAST_DOWNLOAD_DIRECTORY to that directory's string representation
instead of "/tmp/podcasts" so the test is portable and satisfies Ruff S108;
modify the mock_config assignment where mock_config.PODCAST_DOWNLOAD_DIRECTORY
is set to use tmp_path instead of the literal.
- Around line 488-770: Rename unused unpacked test variable `mock_repo` to a
throwaway name (e.g., `_mock_repo` or `_`) in the tests that do `client,
mock_repo = authenticated_client` so Ruff RUF059 is satisfied; update
occurrences in test_add_new_podcast_success, test_add_new_podcast_sync_error,
test_add_new_podcast_exception, and test_add_podcast_feed_url_normalization to
`client, _mock_repo = authenticated_client` (or `client, _ =
authenticated_client`) without changing any logic.

🧹 Nitpick comments (7)

tests/test_feed_parser.py (4)
260-327: Assert parser._session.get() is called with the expected timeout in parse_url tests.

These tests already cover success/error cases well; adding a call-arg assertion makes them more regression-resistant (especially around timeout=self.timeout).
Proposed tweak
@@
-        with patch.object(parser._session, 'get', return_value=mock_response):
+        with patch.object(parser._session, "get", return_value=mock_response) as mock_get:
             podcast = parser.parse_url("https://example.com/feed.xml")
 
+        mock_get.assert_called_once_with("https://example.com/feed.xml", timeout=parser.timeout)
         assert podcast.title == "Test Podcast"
         assert len(podcast.episodes) == 2
348-423: A few tests are “coverage-only” (assert title, comment says feedparser may vary) — consider making them deterministic or removing.

TestCategoryParsing.test_parse_category_as_list, TestMetadataParsing.test_parse_last_build_date, and TestImageExtraction.test_extract_image_fallback currently don’t validate the behavior they claim to test (they effectively just assert parsing didn’t crash). If you want to keep the tests, consider switching to internal helper assertions (as you already do elsewhere) or constructing feedparser-like dicts to validate deterministic outputs.

Also applies to: 540-559

455-518: Avoid encoding known production quirks into tests (“source code has a bug with attribute access”).

The comment in test_link_enclosure_direct suggests the tests are working around a known issue in FeedParser._extract_enclosure’s length handling for link entries. That’s fine for coverage, but it tends to calcify the bug. Consider either:

represent links entries using feedparser.FeedParserDict so attribute access matches real-world behavior, or

add a follow-up issue to fix length parsing (and then add a targeted test for it).

602-623: test_episode_without_title assertion is very broad; it can hide regressions.

assert "iTunes Title" in ... or title == "Untitled Episode" will pass for multiple unexpected outcomes. If the current behavior is well-defined, prefer asserting the exact expected title (or at least one expected branch, not both).
tests/test_podcast_routes.py (3)
734-749: Make the httpx.HTTPStatusError test less brittle by using real httpx.Request/Response.

Using Mock() for request/response can break if the route code touches fields like request.url or response.text. Using real objects keeps the test stable while still fully mocked.
Proposed tweak
@@
-        import httpx
-        mock_request = Mock()
-        mock_response = Mock()
-        mock_response.status_code = 503
-        error = httpx.HTTPStatusError("Service unavailable", request=mock_request, response=mock_response)
+        import httpx
+        request = httpx.Request("GET", "https://example.com/search")
+        response = httpx.Response(503, request=request)
+        error = httpx.HTTPStatusError("Service unavailable", request=request, response=response)
751-770: test_search_limit_clamping doesn’t assert clamping (it’ll pass even if limit stays 100).

If clamping is a requirement, assert the outbound request includes limit=50 (or the expected params). Otherwise this test is mostly “calls happen” coverage.
Example assertion
@@
         response = test_client.get("/api/podcasts/search?q=test&limit=100")
         assert response.status_code == 200
-        # Verify the request was made (clamping happens internally)
-        mock_async_client.get.assert_called_once()
+        mock_async_client.get.assert_called_once()
+        called_url = str(mock_async_client.get.call_args.args[0])
+        assert "limit=50" in called_url
360-399: Lots of duplicated “app_with_mocks/client” fixtures across classes — optional to DRY.

Not a blocker, but if this pattern continues across the suite, a shared fixture (module-level or conftest.py) will reduce maintenance and keep future endpoint additions cheaper.

Also applies to: 579-607, 775-806

464-575: Good coverage of “existing vs already subscribed vs new podcast” add flows.

The “already subscribed” case asserting subscribe_user_to_podcast.assert_not_called() is particularly valuable for preventing side effects/regressions.

3-3: LGTM!

The addition of AsyncMock and MagicMock is appropriate for mocking the async httpx.AsyncClient used in search endpoint tests.

464-485: LGTM!

Good coverage of the "already subscribed" edge case. The test properly verifies that subscribe_user_to_podcast is not called when the user is already subscribed.

487-510: LGTM!

Well-structured test for the new podcast success path with proper mock setup and comprehensive assertions on the response.

534-549: LGTM!

Good coverage of exception handling, verifying that unhandled exceptions result in a 500 status with the error message propagated in the response.

551-573: LGTM!

Clever use of side_effect to verify the URL normalization (feed:// → https://) happens before the repository lookup.

608-639: LGTM!

Comprehensive test for the search endpoint with proper async client mocking. The AsyncMock pattern for __aenter__/__aexit__ correctly simulates the async context manager.

712-727: LGTM!

Good test for timeout handling. Importing httpx inside the test method ensures the correct exception type is used.

807-826: LGTM!

Good test for empty OPML handling, verifying the endpoint gracefully handles zero feeds.

946-971: LGTM!

Good edge case coverage - testing exception handling during individual feed processing while still returning a 200 response with error details in the results.

…onversation ops Add comprehensive tests for previously uncovered repository methods: - Pipeline mode methods: get_download_buffer_count, get_next_for_transcription, get_next_pending_post_processing, increment_retry_count, mark_permanently_failed, reset_episode_for_retry - User operations: create_user, get_user, get_user_by_google_id, get_user_by_email, update_user, list_users, set_user_admin_status, get_user_count - Subscription operations: subscribe/unsubscribe, is_user_subscribed, get_user_subscriptions, list_podcasts_for_user - Email digest operations: get_users_for_email_digest, get_new_episodes_for_user_since, mark_email_digest_sent, get_recent_processed_episodes - Conversation operations: create/get/list/update/delete conversation, add_message, get_messages, count_conversations Repository coverage improved from 53% to 73%.

Add tests for GeminiFileSearchManager: - upload_description_document dry_run mode - _extract_doc_metadata - get_existing_files dry_run - _prepare_metadata edge cases - delete_file dry_run - Batch upload operations - Store operations Coverage improved from 72% to 76% with 1000 tests passing.

Add tests for: - _validate_session_id helper function - Lifespan context manager - API route registration (chat, conversations, podcasts, episodes, search) - Middleware configuration (session, CORS, rate limiter) - App configuration (title, version, state) - Auth endpoints existence Coverage improved to 76% with 1026 tests passing.

Add tests for: - _extract_citations_from_response with various edge cases - create_chat_tools function with different scopes - Tool function names and docstrings - Error handling when store is unavailable Coverage improved to 77% with 1046 tests passing.

…n storage Add comprehensive tests for: - sanitize_query function with injection pattern detection - escape_filter_value for filter value sanitization - Session-based citation storage (get/set/clear) - Session-based filter storage (podcast, episode, list filters) - Thread safety testing for concurrent access - Cleanup functions for TTL-based expiration Coverage improved to 77% with 1079 tests passing.

In @tests/test_gemini_file_search.py:
- Around line 855-876: The test TestSearchMethods.test_search_with_mock is
incomplete (it only sets up mocks and ends with pass); update it to call
GeminiFileSearchManager.search (or the appropriate search method) while patching
manager.client.models.generate_content and manager.create_or_get_store, then
assert on the returned results (e.g., length, content, relevance) and any
expected transformations; alternatively, if the behavior is tested elsewhere,
remove this empty test to avoid misleading coverage.

In @tests/test_podcast_search.py:
- Around line 331-381: The tests test_cleanup_old_citations and
test_cleanup_old_filters lack assertions and may patch time incorrectly; update
both to patch time in the target module
(patch.object(src.agents.podcast_search.time, 'time', ... ) or use monkeypatch
to set src.agents.podcast_search.time.time) so the module sees the old
timestamp, then assert the expected cleanup behavior (e.g., after calling
set_podcast_citations("another-session", []) assert
get_podcast_citations(session_id) is None or empty; similarly after
set_podcast_filter(...) assert get_podcast_filter(session_id) is None or empty),
and remove/replace the unused local variable `result`; reference functions
set_podcast_citations, get_podcast_citations, set_podcast_filter,
get_podcast_filter and constants _session_citations, _session_podcast_filter,

🧹 Nitpick comments (12)

tests/test_web_app.py (1)

666-672: Timing-based test may be flaky in CI.

The 1-second threshold is generous, but timing tests can still fail intermittently in slow CI environments or when runners are under load. Consider either:

Adding @pytest.mark.flaky(reruns=2) if using pytest-rerunfailures

Skipping in CI with a marker like @pytest.mark.skip_in_ci

Increasing the threshold with a comment explaining the rationale
tests/test_chat_tools.py (3)
12-127: Consider extracting common setup into pytest fixtures.

The test setup for mock repository and grounding structures is repeated across multiple tests. Extracting these into fixtures would reduce duplication and improve maintainability.
♻️ Example fixture extraction
@pytest.fixture
def mock_repo():
    return MagicMock()

@pytest.fixture
def mock_grounding_response():
    """Creates a basic grounding response structure."""
    def _create(chunks):
        mock_grounding = MagicMock()
        mock_grounding.grounding_chunks = chunks
        mock_candidate = MagicMock()
        mock_candidate.grounding_metadata = mock_grounding
        mock_response = MagicMock()
        mock_response.candidates = [mock_candidate]
        return mock_response
    return _create
Then tests can be simplified:
def test_extract_citations_transcript_source(self, mock_repo, mock_grounding_response):
    from src.agents.chat_tools import _extract_citations_from_response
    # ... setup episode and chunk ...
    mock_response = mock_grounding_response([mock_chunk])
    citations = _extract_citations_from_response(mock_response, mock_repo)
    # ... assertions ...
524-527: Consider adding a default to next() for clearer failure messages.

If the tool is not found, next() will raise StopIteration with no context. While test_search_transcripts_tool_exists should catch this case, adding a default or using a more explicit approach would improve test diagnostics.
♻️ Suggested improvement
-        # Get search_transcripts tool
-        search_tool = next(t for t in tools if t.__name__ == 'search_transcripts')
+        # Get search_transcripts tool
+        search_tool = next(
+            (t for t in tools if t.__name__ == 'search_transcripts'),
+            None
+        )
+        assert search_tool is not None, "search_transcripts tool not found"
498-567: Consider adding tests for successful search paths and other tools.

The current tests cover error scenarios for search_transcripts and search_podcast_descriptions, but there's no coverage for:

Successful search operations with mocked Gemini responses

The get_user_subscriptions, get_podcast_info, and get_episode_info tools

Since this PR aims to increase test coverage to 95%, consider adding these tests in a follow-up.

Would you like me to help generate test cases for the successful search paths and the remaining tool functions?

1177-1203: Consider adding error field assertions for consistency.

The first mark_permanently_failed test (lines 1172-1175) verifies both the status and error fields, but the metadata and indexing tests only check the status. For consistent coverage, consider also asserting that the error message is stored correctly.
🔧 Suggested fix

684-698: Consider adding a test for actual retry behavior.

This test only verifies success on the first attempt. Based on the _retry_with_backoff implementation (which handles transient failures with exponential backoff), consider adding a test that verifies retry behavior when the function fails initially but succeeds on a subsequent attempt.
💡 Example additional test for retry behavior
def test_retry_with_backoff_retries_on_failure():
    """Test _retry_with_backoff retries on transient failures."""
    config = Config()
    manager = GeminiFileSearchManager(config=config, dry_run=False)

        initial_delay=0.01  # Short delay for test speed
    )
    assert result == "success"
    assert call_count == 3
773-779: Use underscore prefix for unused variable.

The resource_name variable is unpacked but never used. Per Python convention and the static analysis hint, prefix it with an underscore.
♻️ Proposed fix
-    resource_name, display_name = manager.upload_description_document(
+    _resource_name, display_name = manager.upload_description_document(
         podcast_name=long_name,
         description="Description.",
     )
882-901: Test name doesn't match test behavior.

The test is named test_batch_upload_skip_duplicates but it only performs a single upload and doesn't verify duplicate-skipping behavior. Consider either renaming the test to test_batch_upload_single_file or extending it to actually test duplicate skipping by uploading twice and verifying the second upload is skipped.
💡 Example fix to match the test name
def test_batch_upload_skip_duplicates(self, tmpdir):
    """Test batch upload skips duplicate files."""
    config = Config()
    config.BASE_DIRECTORY = str(tmpdir)

    # Create transcript files

16-72: Tests look good, consider consolidating imports at module level.

The test cases comprehensively cover sanitize_query functionality. The function-level imports work for test isolation but could be consolidated at the top of the file for consistency and slight performance improvement during test runs.

133-139: Consider using the constant directly for maintainability.

The hardcoded 500 assumes _MAX_FILTER_VALUE_LENGTH equals 500. If the constant changes in the source, this test will fail unexpectedly.
♻️ Suggested improvement

🔇 Additional comments (28)

tests/test_web_app.py (7)

570-642: Good test coverage for session ID validation.

These tests comprehensively cover the _validate_session_id function's behavior including edge cases like empty strings, invalid characters, and overly long inputs. The test cases align well with the implementation's validation logic.

Minor suggestion: Consider moving the repeated import uuid statements (lines 589, 597, 607, 624) to the top of the file or class level for cleaner code, though this is acceptable as-is for test isolation.

644-654: LGTM!

Basic existence check for the lifespan context manager. This provides coverage confirmation without requiring complex async context manager testing.

675-682: LGTM!

Correctly uses follow_redirects=False to verify redirect behavior and appropriately checks for both 302 and 307 status codes.

685-719: LGTM!

Good pattern for verifying route registration without requiring authentication. The != 404 assertion correctly distinguishes between "route exists but requires auth" (401/403) and "route not found" (404).

721-744: LGTM!

Effective approach for verifying middleware configuration. While string matching on middleware names is somewhat brittle, it's a reasonable tradeoff for configuration verification tests.

747-772: LGTM!

Good configuration verification tests. Note that the hardcoded version "2.0.0" (line 760) will need to be updated when the app version changes, but this also serves as documentation of the expected version.

775-795: LGTM!

Consistent with the route existence testing pattern used elsewhere. Correctly uses appropriate HTTP methods for each endpoint (GET for login/me, POST for logout).

tests/test_chat_tools.py (7)

1-10: LGTM!

Module docstring and imports are appropriate for this test file.

213-265: LGTM!

Good coverage of error handling paths. These tests properly verify that database errors and missing episodes are handled gracefully without raising exceptions.

268-298: LGTM!

Tests properly verify that create_chat_tools returns a list of callable tools. The basic test coverage for tool creation is appropriate.

361-412: LGTM!

Good resilience testing. These tests verify that tool creation gracefully handles failures in podcast fetch and store retrieval without raising exceptions.

415-495: LGTM!

Good contract tests that verify expected tool names exist and all tools have proper documentation. This helps prevent accidental breaking changes to the tool API.

534-567: LGTM!

Consistent test pattern with TestSearchTranscriptsTool. The same optional improvement for next() with a default would apply here as well at line 561.

570-571: LGTM!

Standard pytest entry point for direct execution.

tests/test_repository.py (6)

1030-1098: LGTM! Comprehensive pipeline mode tests.

The tests correctly validate the pipeline workflow methods. The get_next_for_transcription test properly verifies the newest-first ordering, and get_next_pending_post_processing tests cover both metadata and indexing paths.

1268-1442: LGTM! Thorough user operations coverage.

Tests comprehensively cover user CRUD operations including edge cases for nonexistent entities, filtering by admin/active status, and pagination with limit/offset.

1444-1558: LGTM! Good subscription lifecycle coverage.

Tests properly verify the subscription operations including idempotent behavior (subscribing twice returns existing subscription) and sorting options.

1560-1643: LGTM! Email digest tests look solid.

Good coverage for digest eligibility filtering and timestamp updates. The tests correctly verify that inactive users and users with digest disabled are excluded.

1788-1807: LGTM! Timestamp update verification is reasonable.

The time.sleep(0.1) approach to verify timestamp updates is a common pattern. While it slightly increases test runtime, it's acceptable for ensuring the updated_at field changes after adding a message.

1809-1857: LGTM! Message retrieval and conversation counting tests are complete.

Good coverage for pagination with limit/offset and edge case for empty conversation count.

tests/test_gemini_file_search.py (3)

701-731: LGTM!

Good coverage of the _extract_doc_metadata method, including both the populated metadata case and the edge case where custom_metadata is None.

793-843: LGTM!

Good coverage of _prepare_metadata edge cases including empty inputs, type field handling, and key filtering behavior.

932-942: LGTM with a minor observation.

The test verifies that both calls return the same value, which is correct behavior. Note that in dry_run mode, this doesn't strictly prove caching is working (since dry_run always returns a synthetic value). For stronger verification, you could mock the underlying API call and assert it's only called once.

tests/test_podcast_search.py (5)

142-222: LGTM!

Good test coverage for citation storage including copy semantics verification. Proper cleanup in finally blocks ensures test isolation.

224-326: LGTM!

Comprehensive filter storage tests with proper cleanup. The mutual exclusivity test correctly validates the ValueError behavior.

383-445: LGTM!

Thread safety tests are well-structured. The broad Exception catch (flagged by static analysis) is acceptable here since the goal is to capture any failure during concurrent access. The pattern of collecting errors and asserting at the end is appropriate for concurrency testing.

448-469: LGTM!

Good coverage for the deprecated get_latest_podcast_citations function, ensuring backwards compatibility with the _default session.

496-497: LGTM!

Standard pytest entry point for direct execution.

fix: remove tests for non-existent helper functions

bc9a14f
