Test Automation Project

A comprehensive test automation solution featuring a React TypeScript frontend and Node.js backend with full test coverage and modern CI/CD practices.

🚀 Quick Setup (1-2 minutes)

Prerequisites

• Node.js 18+ and npm (or yarn)

⚡ One-Command Setup (Recommended)

# Clone and setup everything in one go
git clone <repository-url>
cd remtest
npm run setup

🔧 Manual Setup (Alternative)

# 1. Install dependencies
npm run install:all

# 2. Setup Playwright browsers
cd client && npx playwright install --with-deps

# 3. Start both servers
npm run dev

🎯 What You Get

• Frontend: React app running on http://localhost:3000
• Backend: API server running on http://localhost:3001
• Tests: Ready to run with full coverage
• Login: Use admin / password

🧪 Testing

🔄 CI/CD Pipeline

Main CI Workflow (main.yml)

• Triggers: Pull requests and pushes to main/master
• Purpose: Full CI pipeline with linting, testing, and building
• Steps:
  1. Lint code with ESLint
  2. Run API tests with Jest
  3. Build React client
  4. Run E2E tests with Playwright

Pipeline Features

• Parallel Execution: API and UI tests run simultaneously
• Coverage Reporting: Integrated with Codecov
• Test Artifacts: Screenshots and reports on failures
• Health Checks: Reliable server startup validation
• Dependency Caching: Optimized for fast builds

Code Quality Workflows

• Lint Workflow: ESLint checks on both API and client
• Auto-Fix Workflow: Automated code formatting and commits

🛠️ Application Features

Authentication System

• JWT-based authentication with bcrypt password hashing
• Session persistence using localStorage
• Default credentials: admin / password
• Comprehensive error handling and validation

Todo Management

• CRUD Operations: Create, Read, Update, Delete todos
• Fields: Title (required), description (optional), completion status
• Features: Edit in-place, bulk operations, creation timestamps
• User Isolation: Todos are user-specific and secure

Technical Stack

• Frontend: React 18, TypeScript, CSS
• Backend: Node.js, Express, JWT, bcrypt, UUID
• Testing: Playwright, Jest, Supertest
• Quality: ESLint, TypeScript compiler
• CI/CD: GitHub Actions, npm scripts

📊 Test Coverage Details

API Coverage (85.36%)

• Authentication: Login, logout, token validation
• Todo CRUD: All endpoints with error scenarios
• Security: JWT middleware, user isolation
• Error Handling: Invalid requests, unauthorized access

UI Coverage (18/18 tests)

• Authentication: Login/logout workflows
• Todo Management: Full CRUD operations
• User Experience: Form validation, state management
• Edge Cases: Empty states, error handling

🚨 Known Issues & Limitations

Current Limitations

• Data Persistence: In-memory storage (resets on server restart)
• Single User: Designed for single-user scenarios
• No Real Database: Uses in-memory arrays
• No Concurrent Support: Single-user application design

Technical Constraints

• No real database integration
• No concurrent user support
• No offline functionality
• No file upload capabilities
