This skill helps you write and run Python tests with pytest, fixtures, mocking, and coverage, boosting test quality and confidence.

This skill helps you master advanced TypeScript types including generics, conditionals, and mapped types to build robust type-safe code.

This skill helps you write type-safe TypeScript tests, configure ts-jest and Vitest, and create typed mocks and type-checking test utilities.

This skill helps you add focused backend tests to verify invariants, endpoint behavior, and retries across services.

This skill helps you write efficient C code with memory management, system calls, and embedded optimization for performance-critical projects.

This skill enables rapid test authoring with reusable 46 methods, base cases, and traits across unit, feature, and browser tests.

This skill helps you write robust tests by emphasizing integration tests, real fixtures, and regression coverage while mocking external services.

This skill guides you through test-driven development cycles, ensuring 80%+ coverage via red-green-refactor, with tests, code, and refactor steps.

This skill helps you create thorough unit tests for individual functions and classes with proper mocks, assertions, and coverage.
