Testing Philosophy

This project follows a testing pyramid approach:

• Many unit tests (fast, isolated)
• Fewer integration tests (verify component interaction)
• Few E2E tests (critical user paths only)

Test Types

Unit Tests

Location: tests/unit/ Purpose: Test individual functions and components in isolation Run: npm test or pytest tests/unit

What to test:

• Pure functions (utils, helpers)
• Component rendering
• State management logic
• Data transformations

Integration Tests

Location: tests/integration/ Purpose: Test API endpoints and component interactions Run: npm test tests/integration or pytest tests/integration

What to test:

• API endpoint responses
• Database operations
• Authentication flows
• Multi-component interactions

E2E Tests (Optional)

Location: tests/e2e/ Purpose: Test complete user flows Run: npm run test:e2e

What to test:

• Critical user journeys
• Happy path flows
• Authentication end-to-end

Test Commands

Coverage Goals

Current: {current}% Target: 70-80% for critical paths

Focus coverage on:

• Business logic
• API endpoints
• Authentication
• Data validation

Writing New Tests

Naming Convention

• Test files: *.test.ts or *.spec.ts
• Test descriptions: "should [expected behavior] when [condition]"

Test Structure

Copydescribe('ComponentName', () => {
  describe('method or behavior', () => {
    it('should do something when condition', () => {
      // Arrange
      // Act
      // Assert
    })
  })
})

Best Practices

1. One assertion per test (when practical)
2. Test behavior, not implementation
3. Use descriptive test names
4. Keep tests independent
5. Mock external dependencies

CI Integration

Tests run automatically on:

• Every push to main and dev branches
• Every pull request

See .github/workflows/ci.yml for configuration.

Resources

• Testing Library Docs
• Vitest Docs
• Pytest Docs

## Test Infrastructure Setup Complete

**Project:** {project_name}
**Framework:** {test_framework}

---

### Files Created

- {config_file} - Test framework configuration
- tests/setup.{ext} - Test setup and global mocks
- tests/unit/example.test.{ext} - Example unit test
- tests/integration/api.test.{ext} - Example integration test
- .docs/test-strategy.md - Testing strategy documentation

---

### Test Commands

```bash
# Run all tests
{run_command}

# Run tests in watch mode
{watch_command}

# Run with coverage
{coverage_command}

---

What's Next

Your testing infrastructure is set up. Here's how to proceed:

1. Run the example tests to verify setup:

   Copy{run_command}
   

2. Write tests as you build features:

   • Write tests before or alongside new code
   • Focus on critical business logic first
   • Use example tests as templates

3. Maintain test health:

   • Keep tests passing
   • Review coverage periodically
   • Update tests when behavior changes

---

Educational Notes

Testing Pyramid:

• Unit tests are fast and numerous - test small pieces in isolation
• Integration tests verify components work together
• E2E tests are slow but valuable for critical paths

When to write tests:

• Before implementing (TDD) - helps design better code
• After implementing - validates behavior
• When fixing bugs - prevent regression

Test-Driven Development (TDD) cycle:

1. Write a failing test
2. Write minimum code to pass
3. Refactor while keeping tests green

---

Workflow Status

This is an optional phase in the Skills workflow.

Previous: Phase 3 (project-spinup) - Project foundation Current: Phase 4 (test-orchestrator) - Test infrastructure Next: Phase 5 (deploy-guide) - Deploy your application

You can continue building features and write tests as you go. When ready to deploy, use the deploy-guide skill.

---

Status: Phase 0: Project Brief (project-brief-writer) Phase 1: Tech Stack (tech-stack-advisor) Phase 2: Deployment Strategy (deployment-advisor) Phase 3: Project Foundation (project-spinup) <- TERMINATION POINT (localhost) Phase 4: Test Strategy (you are here) - optional Phase 5: Deployment (deploy-guide) <- TERMINATION POINT (manual deploy) Phase 6: CI/CD (ci-cd-implement) <- TERMINATION POINT (full automation)
