Coverage Thresholds

| Level | Coverage | Use Case | |-------|----------|----------| | Minimum | 60% | Legacy code | | Standard | 80% | Normal development | | High | 90% | Critical systems | | detailed | 95%+ | Safety-critical |

Quality Metrics

Structure

[ ] Clear test organization
[ ] Meaningful test names
[ ] Proper setup/teardown
[ ] Isolated test cases

Coverage

[ ] Critical paths covered
[ ] Edge cases tested
[ ] Error conditions handled
[ ] Integration points verified

Maintainability

[ ] DRY test code
[ ] Reusable fixtures
[ ] Clear assertions
[ ] Minimal mocking

Reliability

[ ] No flaky tests
[ ] Deterministic execution
[ ] No order dependencies
[ ] Fast feedback loop

Detailed Topics

For implementation patterns and examples:

Anti-Patterns - Common testing mistakes with before/after examples
Best Practices - Core testing principles and exit criteria
Content Assertion Levels - L1/L2/L3 taxonomy for testing LLM-interpreted markdown files

Integration with Plugin Testing

This skill provides foundational standards referenced by:

pensive:test-review - Uses coverage thresholds and quality metrics
parseltongue:python-testing - Uses anti-patterns and best practices
sanctum:test-* - Uses quality checklist and content assertion levels for test validation
imbue:proof-of-work - Uses content assertion levels to enforce Iron Law on execution markdown

Verification: Run pytest -v to verify tests pass.

Troubleshooting

Common Issues

Tests not discovered Ensure test files match pattern test_*.py or *_test.py. Run pytest --collect-only to verify.

Import errors Check that the module being tested is in PYTHONPATH or install with pip install -e .

Async tests failing Install pytest-asyncio and decorate test functions with @pytest.mark.asyncio
