This directory contains tests for the Blueprint project.

• conftest.py: Contains pytest fixtures and shared test configuration.
• unit/: Contains unit tests for specific modules.

Run all tests using pytest:

# From project root
pytest

# Run with verbose output
pytest -v

# Run specific test file
pytest tests/unit/test_commit_generator.py

The conftest.py file provides several fixtures that are useful for testing:

• sample_git_diff: A sample git diff for testing diff parsing functionality.
• sample_ai_response: A sample AI service response for testing commit message generation.

When adding new tests:

1. Use the pytest fixture system where appropriate.
2. Mock all external dependencies (subprocess, network calls, etc.).
3. Follow the Arrange-Act-Assert (AAA) pattern in test methods.
4. Add docstrings to test functions that explain what's being tested.

To generate a test coverage report:

# From project root
pytest --cov=blueprint tests/

# Generate HTML report
pytest --cov=blueprint --cov-report=html tests/

• Use unittest.mock.patch to mock dependencies like subprocess calls and AIService.
• When testing functions that call git commands, mock subprocess functions.
• For AI service interactions, mock the AIService class and its methods.
