Integration Test Design

Q: What is a Claude Code skill and how does the Integration Test Design skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Integration Test Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

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).

What this skill does

Integration Test Design is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/integration-test-design/ and loads when your prompt matches the skill's trigger.
