Use when designing tests that verify the interaction between two or more units of a system — modules, services, layers, processes: the scope-and-boundary primitives that distinguish integration from unit and e2e tests, the test-pyramid (Cohn 2009) and test-trophy (Dodds) frameworks for how much integration testing belongs in the suite, the real-vs-faked-collaborator decision per dependency, the test-data lifecycle (per-test setup, transaction rollback, container reset), the difference between sociable-unit tests, integration tests, and contract tests, and the failure modes (over-broad scope that mimics e2e, over-narrow scope that mimics unit, shared mutable state that produces flakes). Do NOT use for testing one unit in isolation (use testing-strategy + test-doubles-design), full user-journey testing (use e2e-test-design), consumer-driven contract verification (use contract-testing), or test-suite quality measurement (use mutation-testing).

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
