Testing Deliverables

Unit Tests

// Backend: Service layer tests
describe('UserService', () => {
  it('should create user with hashed password', async () => {
    const user = await userService.create({
      email: 'test@example.com',
      password: 'SecurePass123!',
    });
    expect(user.password).not.toBe('SecurePass123!');
    expect(user.email).toBe('test@example.com');
  });
});

// Frontend: Component tests
describe('UserForm', () => {
  it('should validate email format', async () => {
    render(<UserForm onSubmit={jest.fn()} />);
    await userEvent.type(screen.getByLabelText('Email'), 'invalid');
    await userEvent.click(screen.getByText('Submit'));
    expect(screen.getByText(/invalid email/i)).toBeInTheDocument();
  });
});

Integration Tests

// API endpoint tests
describe('POST /api/users', () => {
  it('should create user and return 201', async () => {
    const response = await request(app)
      .post('/api/users')
      .send({ email: 'new@example.com', password: 'Pass123!' });

    expect(response.status).toBe(201);
    expect(response.body).toHaveProperty('id');
    expect(response.body.email).toBe('new@example.com');
  });

  it('should return 422 for duplicate email', async () => {
    await createUser({ email: 'existing@example.com' });

    const response = await request(app)
      .post('/api/users')
      .send({ email: 'existing@example.com', password: 'Pass123!' });

    expect(response.status).toBe(422);
    expect(response.body.error.code).toBe('DUPLICATE_EMAIL');
  });
});

E2E Tests

// Playwright test
test('complete user registration flow', async ({ page }) => {
  await page.goto('/register');
  await page.fill('[name="email"]', 'newuser@example.com');
  await page.fill('[name="password"]', 'SecurePass123!');
  await page.click('button[type="submit"]');

  await expect(page).toHaveURL('/dashboard');
  await expect(page.locator('[data-testid="welcome-message"]'))
    .toContainText('Welcome');
});

Test Coverage Requirements

• Unit tests: >80% coverage
• Integration tests: All critical paths
• E2E tests: Main user journeys
• Performance tests: Load/stress scenarios

# Feature: User Management API

## Overview
Complete CRUD API for user management with authentication and authorization.

## Endpoints

### Create User
POST /api/v1/users

Request:
{
  "email": "user@example.com",
  "name": "John Doe",
  "password": "SecurePass123!"
}

Response (201):
{
  "id": "usr_abc123",
  "email": "user@example.com",
  "name": "John Doe",
  "createdAt": "2025-01-15T10:00:00Z"
}

### Authentication
All endpoints except POST /users require Bearer token:
Authorization: Bearer <jwt_token>

### Error Responses
422 Validation Error:
{
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Invalid input",
    "details": { "email": ["Must be valid email"] }
  }
}

Component Documentation

/**
 * UserProfileForm - Editable user profile form with validation
 *
 * @example
 * <UserProfileForm
 *   initialData={currentUser}
 *   onSubmit={handleUpdate}
 *   onCancel={() => router.back()}
 * />
 *
 * @param initialData - User data to pre-populate form
 * @param onSubmit - Callback when form is submitted with valid data
 * @param onCancel - Optional callback when user cancels editing
 */

  initialData,
  onSubmit,
  onCancel
