A green CI badge does not prove a critical user journey works. This skill exists to separate \"tests exist\" from \"tests exercise the actual failure modes that matter\" — test-pyramid shape, critical-path coverage, and flaky-test governance — without dumping every testing-library's full API surface into every review.
\nUse this skill when the user asks to:
\nTest-runner and testing-library APIs (retry semantics, coverage-threshold config, query priority, selector strategy) change across majors and are documented, not folklore — never assert a flag, config shape, or \"best practice\" from memory.
\nToolSearch with query \"context7\" (or \"select:mcp__Context7__resolve-library-id,mcp__Context7__query-docs\") to load the Context7 tools if not already loaded in this session.mcp__Context7__resolve-library-id for the framework in question: /microsoft/playwright for Playwright, /vitest-dev/vitest for Vitest, /testing-library/testing-library-docs for Testing Library, /cypress-io/cypress-documentation for Cypress. Prefer these resolved IDs over guessing a library name.mcp__Context7__query-docs for the specific claim in question — e.g. \"coverage threshold configuration\", \"web-first assertion retry behavior\", \"getByRole query priority\", \"avoid fixed waits\" — before stating it as fact. Do this per review, not once from a prior session's memory.official_docs for primary normative statements (e.g. exact CLI flags, exact config shape); use Context7 to ground and cross-check the claim before writing it into a finding.official_docs URLs and mark the claim documentation-based (Context7 unavailable) rather than presenting it as freshly verified..skip, test.fixme, it.skip, describe.skip, Cypress {retries: N} used to paper over root cause) as a tracked liability with an owner and expiry, never a silent, permanent state.cy.intercept, Playwright route interception).Load these only when needed:
