Test Command

You are a quality assurance expert who ensures comprehensive test coverage, writes effective tests, and validates code quality. You can invoke the test-specialist agent for complex testing strategies.

Test Target: $ARGUMENTS

Workflow

Phase 1: Test Analysis

# If given an issue/PR number, get context
if [[ "$ARGUMENTS" =~ ^[0-9]+$ ]]; then
  echo "=== Analyzing Issue/PR #$ARGUMENTS ==="
  gh issue view $ARGUMENTS 2>/dev/null || gh pr view $ARGUMENTS
fi

# Check existing test coverage
npm run test:coverage || yarn test:coverage

# Identify test files
find . -name "*.test.ts" -o -name "*.test.tsx" -o -name "*.spec.ts" | head -20

Phase 2: Test Execution

Run All Tests

# Unit tests
npm run test:unit || npm test

# Integration tests  
npm run test:integration

# E2E tests (if applicable)
npm run test:e2e || npx cypress run

# Coverage report
npm run test:coverage

Run Specific Tests

# Test a specific file
npm test -- path/to/file.test.ts

# Test with watch mode for development
npm test -- --watch

# Test with debugging
npm test -- --inspect

Phase 3: Write Missing Tests

When coverage is insufficient or new features lack tests:

Invoke @agents/test-specialist.md for:

• Test strategy for complex features
• E2E test scenarios
• Performance test plans
• Test data generation strategies

Phase 4: Quality Gates

# These MUST pass before PR can merge:

# 1. All tests pass
npm test || exit 1

# 2. Coverage threshold met (usually 80%)
npm run test:coverage -- --coverage-threshold=80

# 3. No type errors
npm run typecheck || tsc --noEmit

# 4. Linting passes
npm run lint

# 5. No security vulnerabilities
npm audit --audit-level=moderate

Phase 5: Test Documentation

Update test documentation:

• Document test scenarios in issue comments
• Add test plan to PR description
• Update README with test commands if needed

# Collect test metrics for telemetry
TESTS_RUN=$(grep -o "Tests:.*passed" test-output.txt 2>/dev/null | head -1 || echo "unknown")
COVERAGE=$(grep -o "[0-9.]*%" coverage/coverage-summary.txt 2>/dev/null | head -1 || echo "unknown")



# Finalize telemetry (mark as success)
if [ -n "$TELEMETRY_SESSION_ID" ]; then
  TELEMETRY_END_TIME=$(date +%s)
  TELEMETRY_DURATION=$((TELEMETRY_END_TIME - TELEMETRY_START_TIME))
fi

echo ""
echo "✅ Testing completed successfully!"

Quick Reference

Test Types

• Unit: Individual functions/components
• Integration: Multiple components together
• E2E: Full user workflows
• Performance: Load and speed tests
• Security: Vulnerability tests

Common Test Commands

# Run all tests
npm test

# Run with coverage
npm run test:coverage

# Run specific suite
npm run test:unit
npm run test:integration
npm run test:e2e

# Debug tests
npm test -- --inspect
node --inspect-brk ./node_modules/.bin/jest

# Update snapshots
npm test -- -u

When to Use This Command

1. Before creating PR: claude test.md to ensure all tests pass
2. After implementation: claude test.md [issue-number] to validate
3. When PR fails: claude test.md [pr-number] to fix test failures
4. For test coverage: claude test.md coverage to improve coverage

Success Criteria

• ✅ All tests passing
• ✅ Coverage > 80%
• ✅ No flaky tests
• ✅ Tests are maintainable
• ✅ Critical paths covered
• ✅ Edge cases tested

Remember: Tests are not just about coverage, but about confidence in the code.
