Walkthrough

This PR implements a complete Python-based AquaSec Scan Results GitHub Action with authentication, input validation, and structured logging. It introduces an AquaSecAuthenticator class for API token generation, ActionInputs class for input validation, and a refactored action.yml to orchestrate the setup and execution flow.

Changes

Cohort / File(s) Summary
Documentation & Configuration
action.yml, .github/copilot-instructions.md, DEVELOPER.md, README.md, .gitignore
Adds comprehensive project documentation, contributor guidelines, and Python-specific tooling configurations; replaces simple echo step in action.yml with full Python setup, dependency installation, and action execution.
Core Application Logic
main.py
Implements run() entrypoint with logging setup, ActionInputs validation, AquaSecAuthenticator invocation, error handling with system exit codes, and structured logging around script lifecycle.
Input Handling & Validation
src/action_inputs.py

@copilot review

Code review completed. Fixed critical bug where bearer token was not being set as GitHub Actions output.

Changes made (commit f7e6000):

  • Added set_action_output() function to src/utils/utils.py
  • Updated main.py to call set_action_output("bearer-token", bearer_token)
  • Added comprehensive tests for the new function

Quality checks - all passing:

  • ✅ Pylint: 10.0/10
  • ✅ Test coverage: 99.14% (21/21 tests passing)
  • ✅ Black: code formatting correct
  • ✅ Mypy: no type errors

The action now properly outputs the bearer token for use in downstream workflow steps.

🤖 Fix all issues with AI agents
In `@action.yml`:
- Around line 28-33: The "Prepare environment variables" step currently echoes
raw inputs (INPUT_AQUA_KEY, INPUT_AQUA_SECRET, INPUT_VERBOSE_LOGGING) into
$GITHUB_ENV which can leak secrets into logs; before writing each sensitive
input (at least inputs.aqua-key and inputs.aqua-secret) call the GitHub Actions
masking command (::add-mask::${{ inputs.aqua-key }} and ::add-mask::${{
inputs.aqua-secret }}) so the values are redacted in logs, then write them to
$GITHUB_ENV as before; update the step named "Prepare environment variables" to
emit the add-mask lines for the two secrets prior to echoing into $GITHUB_ENV.

In `@main.py`:
- Around line 44-48: The bearer_token returned by
AquaSecAuthenticator().authenticate() is never written to GitHub Actions
outputs; after successful assignment to bearer_token in the try block, write the
token to GITHUB_OUTPUT (append a line like "bearer-token=<token>" to the file at
os.environ['GITHUB_OUTPUT']) so it is available as
steps.auth.outputs.bearer-token, and in the except block replace logger.error
with logger.exception to log the stack trace when catching (ValueError,
RequestException) as e; reference AquaSecAuthenticator.authenticate, the
bearer_token variable, and the except block surrounding the authenticate call
when making these changes.

In `@src/model/authenticator.py`:
- Around line 98-104: Wrap the call to response.json() in a try/except to catch
JSON parsing errors and unexpected response shape: call response.json() inside a
try block, catch json.JSONDecodeError (or ValueError for compatibility) and
raise a clear ValueError including response.status_code and response.text; then
validate the parsed payload contains the expected "data" key and non-empty
bearer_token (the variable bearer_token) and raise a ValueError with context if
missing. This change should be applied around the existing response.json() usage
(where bearer_token is assigned) to ensure malformed JSON or missing keys are
handled gracefully.

In `@tests/utils/test_logging_config.py`:
- Around line 60-75: The tests test_setup_logging_verbose_logging_enabled and
test_setup_logging_debug_mode_enabled_by_ci set environment variables but do not
restore them; update these tests to use pytest's monkeypatch fixture (e.g.,
monkeypatch.setenv("INPUT_VERBOSE_LOGGING", "true") and
monkeypatch.setenv("RUNNER_DEBUG", "1")) or explicitly save and restore
os.environ around the calls to setup_logging so environment state is isolated;
keep the rest of the test logic (caplog, setup_logging, validate_logging_config,
mock_logging_setup) unchanged.
🧹 Nitpick comments (7)
.github/copilot-instructions.md (1)

33-33: Assert pattern differs from common pytest convention.

The documented pattern assert expected == actual reverses the typical pytest convention of assert actual == expected. While functionally equivalent, the conventional order improves assertion error readability (e.g., "AssertionError: assert 5 == 10" reads as "actual was 5, expected 10").

Consider aligning with the common convention or explicitly noting this is a project-specific choice.

src/utils/utils.py (1)

24-24: Unused logger import.

The logger is initialized but not used anywhere in this module. Consider removing it to keep the code clean, or add a comment if it's intended for future use.

♻️ Suggested fix
-import logging
 import os
-
-logger = logging.getLogger(__name__)
tests/test_main.py (1)

30-36: Consider adding assertions for the successful path.

The test verifies that run() completes without raising an exception, but doesn't assert that the expected methods were called or that the token was processed. Adding assertions would make the test more robust.

♻️ Suggested improvement
 def test_run_successful(mocker):
     mocker.patch("main.setup_logging")
-    mocker.patch("main.ActionInputs.validate", return_value=True)
-    mocker.patch("main.AquaSecAuthenticator.authenticate", return_value="test_token")
+    mock_validate = mocker.patch("main.ActionInputs.validate", return_value=True)
+    mock_authenticate = mocker.patch("main.AquaSecAuthenticator.authenticate", return_value="test_token")
 
     run()
+
+    mock_validate.assert_called_once()
+    mock_authenticate.assert_called_once()
tests/model/test_authenticator.py (1)

29-36: Consider adding a deterministic signature verification test.

The current test only verifies the output is a 64-character hex string. Adding a test with known input/output would verify the HMAC-SHA256 implementation correctness.

♻️ Suggested additional test
def test_generate_signature_returns_correct_hmac():
    import hmac
    import hashlib

    authenticator = AquaSecAuthenticator()
    authenticator.api_secret = "known_secret"
    test_input = "known_input"

    actual = authenticator._generate_signature(test_input)

    expected = hmac.new(
        b"known_secret", b"known_input", hashlib.sha256
    ).hexdigest()
    assert actual == expected

Regarding the static analysis hint (S105): This is a false positive—using a hardcoded test secret in unit tests is appropriate and expected.

tests/utils/test_utils.py (1)

36-42: Consider adding a test for the default value parameter.

The get_action_input function accepts a default parameter that isn't explicitly tested here.

♻️ Suggested additional test
def test_get_input_returns_default_when_env_var_not_set(mocker):
    mocker.patch("os.getenv", return_value=None)

    actual = get_action_input("missing-input", default="fallback_value")

    assert actual is None  # os.getenv returns None, not the default


def test_get_input_uses_custom_default(mocker):
    mock_getenv = mocker.patch("os.getenv", return_value="custom_default")

    actual = get_action_input("some-input", default="custom_default")

    mock_getenv.assert_called_with("INPUT_SOME_INPUT", default="custom_default")
    assert "custom_default" == actual
src/action_inputs.py (1)

56-80: Consider adding secret masking for GitHub Actions logs.

The PR description mentions "automatic secret masking via ::add-mask::" but this isn't implemented in the validate method. Without masking, if secrets are accidentally logged elsewhere, they could be exposed in the workflow logs.

Proposed addition for secret masking
     def validate(self):
         """
         Validates the action inputs.

         Returns:
             True if all required inputs are valid, False otherwise.
         """
         logger.info("AquaSec Scan Results - Input validation starting.")
         error_count: int = 0
         aquasec_key: str = self.get_aquasec_key()
         aquasec_secret: str = self.get_aquasec_secret()

+        # Mask secrets in GitHub Actions logs
+        if aquasec_key:
+            print(f"::add-mask::{aquasec_key}")
+        if aquasec_secret:
+            print(f"::add-mask::{aquasec_secret}")
+
         if not aquasec_key or not isinstance(aquasec_key, str):
             logger.error("AQUASEC_KEY: str - not provided.")
             error_count += 1
src/model/authenticator.py (1)

73-84: Consider reusing ActionInputs for credential retrieval.

The credentials are fetched directly via get_action_input() here, duplicating the logic in ActionInputs.get_aquasec_key() and get_aquasec_secret(). Consider using ActionInputs for consistency, though this is a minor organizational concern.
