Run Tests

--- description: Runs project tests intelligently. Identifies tests affected by changes and runs them first, followed by the full suite. --- # Run Tests Run tests efficiently using a tiered approach: affected tests first, followed by the full suite. ## Phase 1: Detect Test Framework Identify the testing setup: ``bash # Node.js cat package.json | grep -E '"(jest|vitest|mocha|ava|tap)"' # Python ls pytest.ini pyproject.toml setup.cfg 2>/dev/null | head -1 # Go ls *_test.go 2>/dev/null | head -1 # Rust ls Cargo.toml 2>/dev/null ## Phase 2: Identify Affected Tests Based on git diff, find related tests: bash # Get changed files git diff --name-only HEAD~1 # Find corresponding test files # Convention: foo.ts -> foo.test.ts or foo.spec.ts ## Phase 3: Run Tests (Tiered Approach) ### Tier 1: Affected Tests Only (Fast) bash # Node.js with Jest/Vitest npm test -- --findRelatedTests [changed files] npx vitest run --changed # Python with pytest pytest [specific test files] -x --tb=short # Go go test -run [TestName] ./... ### Tier 2: Full Unit Test Suite If Tier 1 passes: bash npm test pytest tests/unit/ go test ./... cargo test ### Tier 3: Integration Tests If Tier 2 passes: bash npm run test:integration pytest tests/integration/ go test -tags=integration ./... ## Phase 4: Analyze Failures For each failure: 1. Parse error message 2. Identify failing assertion 3. Trace to source code 4. Suggest fix ## Output Format ## Test Results: [PASS/FAIL] ### Summary - Total: X tests - Passed: Y - Failed: Z - Skipped: W - Duration: [time] ### Failed Tests 1. **test_name** - file:line - Expected: [value] - Actual: [value] - Likely cause: [analysis] - Suggested fix: [fix] ### Flaky Test Detection - [Any tests that passed on retry] ### Coverage (if available) - Lines: X% - Branches: Y% - Functions: Z% ### Recommendation [SAFE TO COMMIT / FIX REQUIRED / INVESTIGATE FLAKY] ## Continue Until Green If tests fail: 1. Report the failure clearly 2. Attempt to fix the failing code (not just the test) 3. Re-run tests 4. Repeat until green or max 3 attempts ## Usage This command ships with the project-starter plugin. Invoke with: /project-starter:run-tests
