Can this help with CI/CD optimization?

Yes, by emphasizing FIRST principles (Fast, Isolated, Repeatable, Self-validating, Timely), it ensures your test suite is optimized for rapid CI/CD execution.

Does it support property-based testing?

Yes, the strategy includes guidance and examples for using property-based testing to verify invariants with randomly generated inputs, useful for parsers and mathematical logic.

How does this skill handle mocking?

It provides specific guidelines on when to mock (e.g., external APIs, time, random generators) and when NOT to mock (e.g., the module under test, standard libraries) to avoid brittle tests.

What is the recommended test ratio for this skill?

The skill follows a 70/20/10 split: 70% Unit tests, 20% Integration tests, and 10% End-to-End (E2E) tests to ensure a fast and stable feedback loop.

セキュリティとテスト

Implements a robust test pyramid and standardized testing best practices to ensure code quality across unit, integration, and E2E layers.

The Testing Strategy skill provides Claude with a comprehensive framework for planning and evaluating software tests. It enforces the classic test pyramid (70% unit, 20% integration, 10% E2E), applies FIRST principles for unit tests, and provides clear guidance on mocking, property-based testing, and coverage metrics. This skill is ideal for developers who want to maintain high-quality codebases with deterministic, fast-running test suites while avoiding common anti-patterns like over-mocking or testing implementation details.
