A comprehensive testing companion that covers the full spectrum of Go test patterns, from table-driven unit tests to integration test isolation, goroutine leak detection with goleak, and the new synctest for deterministic concurrency testing. It scaffolds tests using gotests, enforces best practices like t.Parallel() and build tags, and includes audit mode for spotting flakiness and order dependencies in existing suites. The skill pushes hard on testing behavior over coverage targets and treats tests as executable specifications. If you're writing Go tests beyond the basics or reviewing test PRs, this gives you the patterns and guardrails to keep them fast, reliable, and maintainable.
