Running Tests

All Tests

pytest                          # Using pytest directly
python scripts/run_tests.py     # Using test runner

By Category

pytest tests/unit/
pytest tests/integration/
pytest tests/backtest/
pytest -m unit                  # Using markers
pytest -m "integration and not slow"

Specific Tests

pytest tests/unit/test_strategies.py
pytest tests/unit/test_strategies.py::TestDualOutcomeArbitrage
pytest tests/unit/test_strategies.py::TestDualOutcomeArbitrage::test_detect_arbitrage_opportunity
pytest -k "arbitrage"           # Tests matching pattern

With Coverage

# Install pytest-cov first

Test Coverage

Current test coverage by module:

Overall target: >80% code coverage

Key Features

1. Comprehensive Fixtures

• Pre-configured test data for all components
• Easy to use and compose
• Isolated and independent

2. Test Isolation

• Each test runs independently
• No shared state between tests
• Fresh fixtures for each test

3. Clear Test Structure

• Arrange-Act-Assert pattern
• Descriptive test names
• One assertion per test (mostly)

4. Error Cases

• Tests for edge cases
• Error handling validation
• Boundary conditions

5. Integration Coverage

• End-to-end flows
• Multi-component interactions
• Real-world scenarios

Documentation

/Users/rodneymiranda/Documents/Consulting/TailwindTech/polymarket/tests/README.md

Comprehensive testing guide including: - Test structure and organization - Running tests (all options) - Writing new tests - Using fixtures - Best practices - Troubleshooting - CI/CD integration

Next Steps

1. Install Coverage Tools (Optional)

pip install pytest-cov

Then uncomment coverage flags in pytest.ini or use:

pytest --cov=src --cov-report=term-missing

2. Run Initial Test Suite

# Run all tests to verify setup
python scripts/run_tests.py

# Expected: 116 tests collected, all passing

3. Add Tests for New Features

When adding new strategies or features: 1. Add unit tests in tests/unit/ 2. Add integration tests if needed 3. Update fixtures in conftest.py if needed 4. Run tests: pytest -k "your_feature"

4. Set Up CI/CD (Optional)

Example GitHub Actions workflow:

name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-python@v2
        with:
          python-version: '3.10'
      - run: pip install -r requirements.txt
      - run: pytest --cov=src --cov-report=xml
      - uses: codecov/codecov-action@v2

5. Monitor Test Performance

# Show slowest tests
pytest --durations=10

# Profile tests
pytest --profile

Best Practices

1. Run tests before committing bash python scripts/run_tests.py --fast

2. Run full test suite before pushing bash python scripts/run_tests.py --coverage

3. Add tests for bug fixes

4. Write test that reproduces bug
5. Fix bug

6. Verify test passes

7. Keep tests fast

8. Use mocks for external services
9. Use in-memory databases

10. Mark slow tests with @pytest.mark.slow

11. Update tests when refactoring

12. Tests should reflect current behavior
13. Update fixtures if interfaces change
14. Maintain coverage levels

Test Markers

Use markers to categorize tests:

@pytest.mark.unit
def test_unit_functionality():
    """Unit test."""
    pass

@pytest.mark.integration
def test_integration():
    """Integration test."""
    pass

@pytest.mark.slow
def test_long_operation():
    """Slow test."""
    pass

@pytest.mark.requires_db
def test_database():
    """Requires database."""
    pass

Run by marker:

pytest -m unit
pytest -m "not slow"
pytest -m "integration and not requires_db"

Troubleshooting

Tests Not Found

• Ensure you're in project root
• Check file names start with test_
• Check class names start with Test
• Check function names start with test_

Import Errors

• Ensure src/ is in Python path
• Run from project root
• Check all __init__.py files exist

Fixture Not Found

• Check fixture name spelling
• Ensure conftest.py is in correct location
• Check fixture scope

Async Test Issues

@pytest.mark.asyncio
async def test_async():
    result = await async_function()
    assert result is not None
