Run Comprehensive Tests

Run Comprehensive Tests

Purpose

Execute the complete test suite for TypeScript/JavaScript projects, validate results, and provide structured output for workflow decisions.

When to Use

• During Quality Assurance phase of development workflows
• Before creating pull requests
• After implementing new features or bug fixes
• When validating refactoring changes
• As part of CI/CD pipeline validation

Supported Test Frameworks

Works with any test framework:

• Vitest: Modern Vite-based testing
• Jest: Popular React/Node testing
• Mocha/Chai: Traditional Node testing
• Jasmine: Behavior-driven testing
• Detects via package.json scripts or direct commands

Instructions

Step 1: Run Test Suite

# Run all tests with coverage
npm run test

# For CI environments, use CI mode
CI=true npm run test -- --coverage

Step 2: Parse Results

Extract key metrics from test output:

• Total tests: Number of test cases
• Passed: Successfully passing tests
• Failed: Failing tests (with details)
• Coverage: Code coverage percentage
• Duration: Test execution time

Step 3: Analyze Failures (Enhanced)

If tests fail, parse actual error messages from output:

# Extract failure details from test output
# Look for patterns like:
# - "FAIL src/components/Card.test.tsx"
# - "  ● Test suite failed to run"
# - "  Expected: true, Received: false"
# - "    at Object.<anonymous> (src/file.ts:42:15)"

# Parse each failure:
for FAILURE in $(grep -n "FAIL\|●\|Error:" test-output.txt); do
  # Extract file path
  FILE=$(echo "$FAILURE" | grep -oP 'src/[^:]+\.tsx?')

  # Extract error message (not hardcoded "Test failed")
  ERROR_MSG=$(echo "$FAILURE" | grep -oP '(Expected|Error|AssertionError).*' | head -1)

  # Extract line number from stack trace
  LINE=$(echo "$FAILURE" | grep -oP 'at.*:(\d+):' | grep -oP '\d+' | head -1)

  # Store for structured output
done

Categorize failure types:

• Assertion failures: Expected vs Received mismatches
• Type errors: TypeScript type mismatches
• Timeout errors: Test exceeded time limit
• Import errors: Module resolution failures
• Syntax errors: JavaScript/TypeScript syntax issues

Step 4: Return Structured Results

Provide results in this format:

{
  "status": "pass" | "fail",
  "summary": {
    "total": 45,
    "passed": 45,
    "failed": 0,
    "coverage": 87.5,
    "duration": "12.3s"
  },
  "failures": [
    {
      "file": "src/components/CharacterCard.test.tsx",
      "test": "should render character portrait",
      "error": "Expected element to exist",
      "line": 42
    }
  ]
}

Exit Codes

• 0: All tests passed
• 1: One or more tests failed
• 2: Test configuration error

Common Issues

Issue: Tests timeout

Solution: Increase timeout in vite.config.ts:

test: {
  testTimeout: 10000, // 10 seconds
}

Issue: Coverage below threshold

Solution: Check package.json for coverage thresholds and add tests for uncovered code

Issue: Import errors in tests

Solution: Verify test setup in vitest.setup.ts and ensure all mocks are configured

Integration with Conductor Workflow

The Conductor agent uses this skill in Phase 3 (Quality Assurance):

**Phase 3, Step 1**: Run comprehensive tests

Using the `run-comprehensive-tests` skill:
- Execute full test suite
- Validate all tests pass
- Check coverage meets 80% threshold
- If failures: delegate to debugger agent

Related Skills

• validate-coverage - Deep dive into coverage metrics
• debug-test-failures - Systematic test failure debugging
• quality-gate - Complete quality validation workflow

Best Practices

1. Always run tests before committing - Prevents broken builds
2. Fix tests immediately - Don't accumulate test debt
3. Monitor coverage trends - Aim for increasing coverage over time
4. Categorize failures - Helps route to appropriate debugging approach
