Testing Unit Tests

Unit tests isolate individual functions or methods by mocking external dependencies and verifying behavior in controlled conditions. This Skill guides you to structure tests with clear setup, execution, and assertion phases, ensuring each test validates a single component without side effects or integration dependencies.

Unit tests follow naming conventions that clearly describe what they test, organized by the component under test. This Skill enforces standards for test naming, file structure, and grouping so tests remain maintainable, discoverable, and aligned with your codebase's coding standards.

Test-driven development writes tests before implementation, forcing you to design cleaner interfaces and reduce post-release bugs. This Skill supports TDD workflows by helping Claude generate comprehensive test suites covering edge cases and public methods upfront.

Yes. This Skill generates unit tests compatible with continuous integration pipelines and automated test runners. It ensures tests follow CI workflow standards so they integrate seamlessly into build systems and validation gates.

Mocking isolates units under test by replacing external dependencies with controlled substitutes. This Skill defines mocking policies and isolation techniques so your tests validate component logic independently without hitting real databases, APIs, or file systems.

Assertions verify expected behavior with clear, readable syntax aligned to your coding standards. This Skill enforces assertion style consistency and test structure patterns so your suite remains maintainable and communicates intent clearly to other developers.
