How the author describes it

Go testing patterns for production-grade code: subtests, test helpers, fixtures, golden files, httptest, testcontainers, fuzz testing, and testing/synctest. Covers mocking strategies, test isolation, coverage analysis, and test design philosophy. Use when writing tests, improving coverage, reviewing test quality, setting up test infrastructure, or choosing a testing approach. Trigger examples: "add tests", "improve coverage", "write tests for this", "test helpers", "mock this dependency", "integration test", "fuzz test", "flaky test", "synctest", "goroutine leak in tests". Not for: benchmarking methodology (go-performance-review), security testing (go-security-audit), table-driven patterns (go-test-table-driven).
