Does this skill provide guidance on what to mock?

Yes, it includes specific strategies for when to mock external APIs and databases versus when to test against real implementations or pure functions.

How does it help with test organization?

It provides a standardized directory structure and clear naming conventions (e.g., test_[action]_[condition]_[result]) to ensure long-term maintainability.

What testing patterns does this skill support?

The skill supports the Arrange-Act-Assert (AAA) pattern for unit testing and Given-When-Then (BDD) syntax for behavior-driven scenarios.

Can it help me identify edge cases?

Absolutely. It features dedicated checklists for input validation, state management, external dependency failures, and time-based edge cases.

安全与测试

Implement robust, comprehensive testing strategies using industry-standard patterns and best practices for high-quality software delivery.

关于

This skill equips Claude with specialized knowledge to architect high-quality test suites across the entire testing pyramid. It provides structured guidance on Arrange-Act-Assert (AAA) and Behavior-Driven Development (BDD) patterns, advanced mocking strategies, and comprehensive edge-case checklists for input validation, state management, and external dependencies. Whether you're setting up unit tests, integration flows, or E2E scenarios, this skill ensures your test code is maintainable, performant, and follows professional naming conventions while avoiding common pitfalls like flakiness or over-mocking.
