Sprint Challenge - Authentication & Testing

Authentication

Implement secure user authentication using both session-based and JWT approaches.

API Development

Build a RESTful API with proper error handling and data validation.

Testing

Create comprehensive test suites covering unit tests, integration tests, and API endpoints.

Authentication Features

• User Registration: Implement secure password hashing with bcrypt
• Login/Logout: Create secure login endpoints with JWT generation
• Password Security: Apply proper password validation and storage
• JWT Implementation: Use JWTs with appropriate payload structure and expiration
• Protected Routes: Create middleware to verify tokens and protect resources

API Endpoints

• User Management: CRUD operations for user resources
• Protected Routes: Implement token-based access control
• Error Handling: Comprehensive error handling with appropriate status codes
• Data Validation: Validate incoming data before processing
• Response Format: Consistent API response structure

Testing Requirements

• Unit Tests: Test individual functions and components
• Integration Tests: Test interactions between modules
• API Tests: Test API endpoints using Supertest
• Authentication Tests: Verify security measures work as expected
• Test Coverage: Achieve high test coverage across the codebase

Authentication Implementation

Implement a secure authentication system with the following features:

• User registration with password hashing
• Login endpoint that generates JWT tokens
• JWT middleware to protect routes
• Secure password storage and validation
• Proper error handling for auth failures

Testing Requirements

Create comprehensive test suites to verify your implementation:

• API endpoint tests for auth routes
• Unit tests for auth middleware
• Tests for protected routes
• Database operation tests
• Token verification tests

API Documentation

Document your API endpoints with:

• Endpoint descriptions
• Request/response formats
• Authentication requirements
• Error responses
• Example usage with cURL or Postman

Project Guidelines

• RESTful API: Follow RESTful design principles for your endpoints
• Error Handling: Implement comprehensive error handling with appropriate HTTP status codes
• Code Organization: Keep your code modular and well-organized
• Documentation: Write clear documentation for your API endpoints
• Testing: Aim for high test coverage and well-structured tests
