Test Executor Skill
Execute tests, analyze results, and report coverage. Primarily for Go projects.
Activation Triggers
- After code implementation/modification (automatic)
- "test coverage", explicit test requests (manual)
- Before commit or PR creation
Workflow
Phase 1: Determine Test Scope
- Identify target packages from project structure
- Check for Makefile or custom test commands
- Coverage threshold: follow project settings (default 80%)
Phase 2: Execute
# Tests + coverage
go test ./internal/... -coverprofile=coverage.out -covermode=atomic
go tool cover -func=coverage.out
# Benchmarks (on request only)
go test -bench=. -benchmem ./...
Phase 3: Report Results
## Test Results
### Summary
- Tests run: X
- Passed: Y ✅ / Failed: Z ❌
- Coverage: W% (threshold: N%)
- Verdict: [✅ All passing / ⚠️ Issues found / ❌ Critical failures]
### Package Coverage
[package-by-package breakdown]
### Issues
[items needing attention]
### Recommended Actions
[specific next steps]
Failure Analysis
- Identify root cause, not just surface-level error message
- Suggest specific fixes
- Recommend adding tests for the failure scenario
Edge Cases
- No tests found → suggest creating test files
- coverage.out generation failure → troubleshoot
- Flaky test → re-run to confirm
- Build error → distinguish compilation errors from test failures
