Why does this skill prefer integration tests over unit tests?

Integration tests verify how components work together in real scenarios, catching the edge cases and communication bugs that unit tests often miss due to over-mocking.

Will these tests slow down my CI/CD pipeline?

No, the skill is designed with a speed budget in mind, aiming for individual integration tests under 500ms and keeping the full suite execution under one minute whenever possible.

Can I still use this for complex algorithms?

Yes. While the skill prefers integration tests for general flows, it specifically recommends unit tests for pure functions with complex logic, such as sorting, parsing, or heavy calculations.

How does this skill handle mocking?

It recommends mocking only external services, time-dependent behavior, and non-deterministic operations, while favoring real databases and internal services for more accurate results.

安全与测试

Generates high-quality integration and unit tests that focus on real-world behavior while maintaining a fast and maintainable test suite.

The Pragmatic Test Writer skill empowers Claude to author robust test suites by prioritizing integration tests over isolated unit tests, ensuring that code behaves as expected in real-world scenarios. It follows a strict philosophy that tests should reflect actual usage patterns, avoid excessive mocking of internal dependencies, and remain lightning-fast to ensure developer productivity. By focusing on critical business logic, security-sensitive paths, and component integration points, this skill helps developers build reliable software without the maintenance burden of fragile, implementation-heavy tests.
