Issue #50 Implementation Summary

Objective

Restructure tests into unit/integration/e2e directories for better organization and test categorization.

Changes Implemented

Phase 1: Create E2E Directory Structure ✅

• Created tests/e2e/ directory
• Created tests/e2e/__init__.py with package documentation
• Created tests/e2e/conftest.py with placeholder fixtures
• Created tests/e2e/README.md explaining e2e test purpose and guidelines

Phase 2: Move Unit Test Files ✅

Moved 5 files to tests/unit/ (using git mv to preserve history):

1. test_exceptions.py → tests/unit/test_exceptions.py
2. test_logging_config.py → tests/unit/test_logging_config.py
3. test_report_exporter.py → tests/unit/test_report_exporter.py
4. test_documentation_structure.py → tests/unit/test_documentation_structure.py
5. test_conftest_hierarchy.py → tests/unit/test_conftest_hierarchy.py

Added pytestmark = pytest.mark.unit to all unit test files.

Phase 3: Move Integration Test Files ✅

Moved 3 files to tests/integration/ (using git mv to preserve history):

1. test_openrouter.py → tests/integration/test_openrouter.py
2. test_akshare.py → tests/integration/test_akshare.py
3. test_cli_error_handling.py → tests/integration/test_cli_error_handling.py

Added pytestmark = pytest.mark.integration to all integration test files.

Phase 4: Update pytest.ini ✅

Updated pytest.ini to include test subdirectories with explanatory comments:

# Test paths - Structured by test type
# tests/unit/         - Fast, isolated unit tests
# tests/integration/  - Component interaction tests
# tests/e2e/          - End-to-end workflow tests
testpaths =
    tests
    tests/unit
    tests/integration
    tests/e2e

Test Markers Working

• Unit marker: pytest -m unit collects 218 tests
• Integration marker: pytest -m integration collects 33 tests
• Tests run successfully after migration

Git History Preserved

All file moves used git mv to preserve Git history for easier blame/tracking.

Files Modified

1. pytest.ini - Updated testpaths and added comments
2. All moved test files - Added pytestmark declarations
3. New files created in tests/e2e/

Next Steps

The test structure is now ready for:

• Adding new unit tests to tests/unit/
• Adding new integration tests to tests/integration/
• Adding new e2e tests to tests/e2e/
• Running tests by category using markers

Running Tests by Category

# Run only unit tests
pytest -m unit

# Run only integration tests
pytest -m integration

# Run only e2e tests (when they exist)
pytest -m e2e

# Run unit and integration tests
pytest -m "unit or integration"

# Run all tests in a specific directory
pytest tests/unit/
pytest tests/integration/
pytest tests/e2e/
