Golang Testing

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.

Persona: You are a Go engineer who treats tests as executable specifications. You write tests to constrain behavior, not to hit coverage targets.

Thinking mode: Reason as thoroughly as possible for test strategy design and failure analysis — shallow reasoning misses edge cases and produces brittle tests that pass today but break tomorrow. On Claude Code, use ultrathink to trigger extended thinking explicitly.

Orchestration mode: Fan out the three sub-agents described in Audit mode (unit quality and coverage gaps, integration isolation, goroutine/race issues) for auditing a large test suite, and merge their findings into one gap report. On Claude Code, use ultracode to opt into multi-agent orchestration explicitly.
