Test Coverage Breakdown

test_basic.py - Foundation Tests

✅ Configuration validation (API key format, host URL, assistant name)
✅ Pydantic model validation (messages, parameters)
✅ EvaluateAnswerParams model validation (required fields, missing-field errors)
✅ AssistantContextParams multimodal fields (multimodal, include_binary_content, messages-vs-query validator)
✅ Strategic search YAML loading
✅ Key term extraction and pattern substitution
✅ Domain validation

test_integration.py - Workflow Tests

✅ MCP tool integration (all 6 tools)
✅ evaluate_answer success path (scores, per-fact reasoning, token usage)
✅ evaluate_answer free-tier error → VALIDATION_ERROR structured response
✅ assistant_context multimodal params forwarded to client
✅ Recommended workflow: Context first → AI if needed
✅ Multi-assistant switching workflow
✅ Token optimization strategies
✅ Error recovery and fallback scenarios
✅ End-to-end integration testing

test_resilience.py - Production Patterns

✅ Retry logic with exponential backoff and jitter
✅ Circuit breaker (closed → open → half-open → closed)
✅ Response caching with TTL expiration
✅ Bulkhead isolation for concurrency limits
✅ Fallback chains with multiple strategies
✅ Integrated resilience (multiple patterns working together)

test_security.py - Security Tests

✅ API key validation (format, length, character restrictions)
✅ Secure storage (Windows DPAPI, cross-platform fallback)
✅ Secure logging (API key sanitization, structured data)
✅ Input validation (assistant names, model parameters, message content)
✅ Security headers and timeout configurations
✅ Env var priority (PINECONE_API_KEY primary → PINECONE_ASSISTANT_API_KEY fallback)

test_unified_credential.py - Unified Credential Architecture Tests

✅ Credential constants (CREDENTIAL_TARGET == "pinecone_API_KEY", correct file paths)
✅ Storage file path (~/.pinecone_api_key, no separate entropy file)
✅ Internal auth secret (~/.uspto_internal_auth_secret path and "first wins" generation)
✅ entropy_file attribute is None (no legacy separate entropy file)
✅ No old credential strings in codebase
✅ Env var fallback chain (PINECONE_API_KEY → PINECONE_ASSISTANT_API_KEY)

test_entropy_security.py - Entropy & DPAPI Key File Security Tests

✅ Entropy randomness (uniqueness across instances, length checks)
✅ Embedded format (bytes 0-31 = entropy prefix, bytes 32+ = DPAPI encrypted key)
✅ DPAPI round-trip (store → retrieve → verify match)
✅ Tamper detection (modifying embedded entropy bytes breaks decryption)
✅ Internal auth secret creation (generated when missing, reused when present)
✅ No hardcoded entropy in production paths (only in deprecated functions)

test_security_audit.py - Static Security Audit Tests

✅ No hardcoded entropy in non-deprecated code paths
✅ No legacy credential names in codebase
✅ File permission checks (key file mode 0o600 on Linux)
✅ Codebase scans for secret patterns

test_monitoring.py - Monitoring & Observability Tests

✅ Health checks (storage health, API connectivity reporting)
✅ Metrics collection (request counts, latency, error rates)
✅ Circuit breaker state reporting in health output

Environment Setup

API Key Configuration

Pinecone Assistant API Key (Required for real testing):

Purpose: Access to Pinecone Assistant API for document research
Without it: Tests run with mocked responses (full functionality testing)
Get your key: Pinecone Console → API Keys → Assistant API

Setting Environment Variables:

# Windows PowerShell
$env:PINECONE_ASSISTANT_API_KEY="pcsk_your_key_here"
$env:PINECONE_ASSISTANT_HOST="https://prod-1-data.ke.pinecone.io"
$env:PINECONE_ASSISTANT_NAME="your-assistant-name"

# Windows Command Prompt
set PINECONE_ASSISTANT_API_KEY=pcsk_your_key_here
set PINECONE_ASSISTANT_HOST=https://prod-1-data.ke.pinecone.io
set PINECONE_ASSISTANT_NAME=your-assistant-name

# Linux/macOS
export PINECONE_ASSISTANT_API_KEY="pcsk_your_key_here"
export PINECONE_ASSISTANT_HOST="https://prod-1-data.ke.pinecone.io"
export PINECONE_ASSISTANT_NAME="your-assistant-name"

Important: All tests are designed to work without real API keys using mocks. API keys are only needed for testing against live Pinecone Assistant instances.

## Environment Variables Reference

| Variable | Default | Purpose | Test Files Using It |
|----------|---------|---------|---------------------|
| `PINECONE_API_KEY` | None | Pinecone API key (**canonical — preferred**) | test_unified_credential.py, test_security.py, conftest.py |
| `PINECONE_ASSISTANT_API_KEY` | None | Pinecone API key (legacy fallback; still accepted) | test_integration.py, test_security.py, conftest.py |
| `PINECONE_ASSISTANT_HOST` | https://prod-1-data.ke.pinecone.io | Assistant API host URL | test_basic.py, test_integration.py |
| `PINECONE_ASSISTANT_NAME` | None | Assistant instance name | test_basic.py, test_integration.py |

| `ENVIRONMENT` | development | Environment (production enforces HTTPS) | test_security.py |

## Troubleshooting

### Issue: Tests Pass but API Key Warnings

**Cause:** Tests run with mocked responses when no real API key is provided

**This is normal behavior:**
- ✅ All tests validate functionality with mocks
- ✅ No real API calls needed for testing
- ✅ Set `PINECONE_ASSISTANT_API_KEY` only for live API testing

### Issue: "Invalid API Key Format" in Security Tests

**Cause:** Security tests validate API key format

**Solution:** This is expected behavior - security tests verify validation works:
```bash
# These test scenarios are intentional:
tests/test_security.py::TestAPIKeyValidation::test_invalid_api_key_formats PASSED

Issue: Import Errors

Cause: Dependencies not installed or stale installation

Solution:

# With uv
uv sync --reinstall --group dev

# With pip
pip install -e ".[dev]" --force-reinstall

Issue: Async Test Warnings

Cause: Asyncio event loop configuration

Solution:

# Run with asyncio mode enabled
uv run pytest --asyncio-mode=auto

# Or add to pytest.ini (already configured)
asyncio_mode = auto

Issue: Cache Tests Flaky Due to Timing

Cause: TTL timing in cache tests

Solution:

# Run cache tests individually with more time
uv run pytest tests/test_resilience.py::TestResponseCache -v -s

Issue: Windows DPAPI Tests Fail on Linux

Cause: Windows-specific secure storage tests

Solution: This is expected - tests include platform detection:

# Linux users: DPAPI tests skip gracefully
# Windows users: Full DPAPI encryption testing

Issue: Circuit Breaker Tests Timing Out

Cause: Long recovery timeouts in tests

Solution:

# Tests use very short timeouts for speed
# If still timing out, run individually:
uv run pytest tests/test_resilience.py::TestCircuitBreaker::test_circuit_breaker_half_open_state -v

Test Development Guidelines

Shared Test Fixtures (conftest.py)

The test suite uses conftest.py for shared fixtures across all test files, eliminating duplication and ensuring consistency.

Available Fixtures:

Configuration Fixtures

# Standard test settings (used in most tests)
def test_example(mock_settings):
    assert mock_settings.pinecone_assistant_api_key.startswith('pcsk_')

# Environment variables for configuration testing
def test_env_config(mock_env_vars):
    with patch.dict(os.environ, mock_env_vars):
        # Test with environment variables
        pass

# Automatic secure storage mocking (runs for all tests)
# No need to manually mock - handled automatically

YAML Test Data Fixtures

# Temporary YAML file with automatic cleanup
def test_yaml_loading(temp_yaml_file):
    processor = StrategySearchProcessor(yaml_path=temp_yaml_file)
    # File automatically deleted after test

# Pre-configured search processor
def test_strategic_search(search_processor):
    domains = search_processor.get_available_domains()
    # Ready to use, no setup needed

Mock API Response Fixtures

# Mock chat response with proper structure
def test_chat(mock_chat_response):
    assert "message" in mock_chat_response
    assert "citations" in mock_chat_response

# Mock context response
def test_context(mock_context_response):
    assert "chunks" in mock_context_response

# Fully configured mock client
def test_client_operation(mock_assistant_client):
    response = mock_assistant_client.chat(params)
    # Client already configured with standard responses

Benefits:

✅ No duplicate fixture code across test files
✅ Consistent test data throughout suite
✅ Automatic secure storage mocking (no manual setup)
✅ Easy to extend for new tests
✅ Comprehensive documentation for each fixture

See tests/conftest.py for complete fixture documentation with usage examples.

Adding New Tests

Choose appropriate test file:
- test_basic.py - Core functionality, validation
- test_integration.py - Tool integration, workflows
- test_resilience.py - Fault tolerance patterns
- test_security.py - Security, API key validation, secure storage
- test_unified_credential.py - Credential architecture constants and behavior
- test_entropy_security.py - DPAPI encryption, entropy format, tamper detection
- test_security_audit.py - Static codebase scans, file permissions
- test_monitoring.py - Health checks, metrics, observability

Follow naming conventions:

class TestFeatureName:
    def test_specific_behavior(self):
        """Test specific behavior with clear expectations"""

Use shared fixtures from conftest.py:

# Use existing shared fixtures (preferred)
def test_with_shared_fixtures(self, mock_settings, mock_chat_response):
    # Fixtures automatically available from conftest.py
    assert mock_settings.pinecone_assistant_api_key.startswith('pcsk_')
    assert "message" in mock_chat_response

# Only create new fixtures if needed for specific tests
@pytest.fixture
def custom_test_data(self):
    return {"special": "data"}

Mock external dependencies:

@patch('src.assistant_client.Pinecone')
def test_client_functionality(self, mock_pinecone):
    # Mock setup
    # Test implementation

Best Practices

Independent tests: Each test should be self-contained
Clear assertions: Use descriptive assertion messages
Mock external calls: Don't make real API calls in unit tests
Test edge cases: Include boundary conditions and error scenarios
Document purpose: Add docstrings explaining test objectives
Use parametrization: Test multiple inputs efficiently

Example Test Template

"""
Test module for <feature>

Tests cover:
- Success scenarios
- Error handling
- Edge cases
- Integration points
"""

import pytest
from unittest.mock import Mock, patch
from src.config import Settings


class TestFeatureName:
    """Test class for specific feature."""

    @pytest.fixture
    def setup_environment(self):
        """Fixture to set up test environment"""
        # Setup code
        yield environment
        # Cleanup code

    def test_feature_success(self, setup_environment):
        """Test successful feature operation."""
        # Arrange
        environment = setup_environment
        
        # Act
        result = feature_function(environment)
        
        # Assert
        assert result is not None
        assert result.status == "success"

    def test_feature_error_handling(self):
        """Test feature handles errors gracefully."""
        with pytest.raises(ValueError, match="Expected error message"):
            feature_function(invalid_input)
