npx claudepluginhub sethdford/claude-skills --plugin engineer-testingCreate test pyramid and coverage strategy for new feature.
Full integration test plan for multi-component systems.
Check code coverage and use mutation testing to verify test quality.
Design and write unit tests using TDD workflow (Red-Green-Refactor).
Testing multiple components together; contract verification; real I/O (database, HTTP). Use when testing component interactions.
Measuring test quality by mutating code and checking if tests catch mutations.
Load testing, profiling, SLA verification, bottleneck identification.
Generative testing with QuickCheck/Hypothesis; testing properties that should hold for all inputs.
Red-Green-Refactor cycle for test-first development. Write failing test, implement minimal code, refactor safely. Use when developing new features or fixing bugs in test-driven projects.
