Standardizes unit and component testing practices using modern tools like Vitest, MSW, and Testing Library.
This skill provides Claude with domain-specific patterns and best practices for implementing high-quality unit and component tests. It focuses on modern testing stacks involving Vitest and Testing Library, emphasizing behavior-driven testing over implementation details. By providing structured guidance on MSW for network mocking, Arrange-Act-Assert patterns, and async testing strategies, it ensures that your test suites are resilient, maintainable, and highly effective at catching regressions.
