How does this skill help with flaky tests?

It enforces condition-based waiting patterns using a polling mechanism instead of arbitrary timeouts, ensuring tests only proceed when the required state is actually met.

When should I use mocking according to this skill?

Mocks should be used strategically for unmanaged external dependencies like third-party APIs or SMTP servers, while managed dependencies like your own database should ideally use real instances.

Does this skill support property-based testing?

Yes, it includes specific quality gates and use-case identification for property-based testing, particularly for pure functions, validators, and serialization.

What is the core testing philosophy used?

The skill follows the philosophy of 'Write tests. Not too many. Mostly integration,' focusing on verifying real-world behavior rather than internal implementation details.

보안 및 테스팅

Implements a robust testing philosophy focused on integration patterns, condition-based waiting, and strategic mocking.

This skill equips Claude with a specialized framework for authoring and reviewing high-quality software tests. It prioritizes testing behavior over implementation details, favoring integration tests that provide the highest confidence-to-cost ratio. By enforcing standards like condition-based waiting (instead of flaky timeouts), strategic mocking of unmanaged dependencies, and strict test isolation, this skill helps developers build resilient test suites that survive refactoring and minimize CI/CD failures.
