🧪 RBAC Project Testing Guide

This guide will help you test the complete functionality of the RBAC project, including the new refresh token mechanism.

📋 Prerequisites

1. Install Dependencies

   npm install

2. Set up Environment Variables
   Create a .env file in the root directory:

   PORT=5000
   MONGO_URI=mongodb://localhost:27017/rbac
   JWT_SECRET=your-super-secret-jwt-key-here
   JWT_EXPIRY=1d
   REFRESH_TOKEN_SECRET=your-super-secret-refresh-token-key-here
   REFRESH_TOKEN_EXPIRY=7d
   CORS_URL=http://localhost:3000

3. Start MongoDB
   Make sure MongoDB is running on your system.

🚀 Step-by-Step Testing

Step 1: Start the Server

npm run dev

You should see: Server is running at port : 5000

Step 2: Seed the Database

node src/seed/seedRoles.js

You should see:

Connected to MongoDB
Created permission: User Actions
Created permission: Manage Users
Created permission: Manage Roles
Created role: Admin
Created role: User
Seeding completed!

Step 3: Test the API Endpoints

3.1 Test Server Health

curl http://localhost:5000/

Expected response: RBAC is running...

3.2 Test User Registration

curl -X POST http://localhost:5000/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{
    "username": "testuser",
    "email": "[email protected]",
    "fullname": "Test User",
    "password": "password123"
  }'

Expected response:

{
  "success": true,
  "message": "User registered successfully",
  "user": {
    "id": "user_id",
    "username": "testuser",
    "email": "[email protected]",
    "role": "User"
  }
}

3.3 Test User Login (with Refresh Token)

curl -X POST http://localhost:5000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "email": "[email protected]",
    "password": "password123"
  }'

Expected response:

{
  "success": true,
  "message": "Login successful",
  "accessToken": "jwt_token_here",
  "refreshToken": "refresh_token_here",
  "user": {
    "id": "user_id",
    "username": "testuser",
    "email": "[email protected]",
    "fullname": "Test User",
    "role": "User"
  }
}

Save the tokens for next steps!

3.4 Test Protected Endpoint

curl -X GET http://localhost:5000/api/rbac-test/user-only \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

Expected response:

{
  "message": "Welcome, User"
}

3.5 Test Token Refresh

curl -X POST http://localhost:5000/api/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{
    "refreshToken": "YOUR_REFRESH_TOKEN"
  }'

Expected response:

{
  "success": true,
  "message": "Token refreshed successfully",
  "accessToken": "new_jwt_token_here",
  "user": {
    "id": "user_id",
    "username": "testuser",
    "email": "[email protected]",
    "fullname": "Test User",
    "role": "User"
  }
}

3.6 Test Logout

curl -X POST http://localhost:5000/api/auth/logout \
  -H "Content-Type: application/json" \
  -d '{
    "refreshToken": "YOUR_REFRESH_TOKEN"
  }'

Expected response:

{
  "success": true,
  "message": "Logged out successfully"
}

3.7 Test Refresh After Logout (Should Fail)

curl -X POST http://localhost:5000/api/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{
    "refreshToken": "YOUR_REFRESH_TOKEN"
  }'

Expected response:

{
  "success": false,
  "message": "Invalid refresh token"
}

🔧 Using Postman/Insomnia

Collection Setup

1. Create a new collection called "RBAC API"
2. Set base URL: http://localhost:5000/api

Request Examples

1. Register User

• Method: POST
• URL: {{base_url}}/auth/register
• Body (JSON):

{
  "username": "testuser",
  "email": "[email protected]",
  "fullname": "Test User",
  "password": "password123"
}

2. Login User

• Method: POST
• URL: {{base_url}}/auth/login
• Body (JSON):

{
  "email": "[email protected]",
  "password": "password123"
}

3. Test Protected Route

• Method: GET
• URL: {{base_url}}/rbac-test/user-only
• Headers:
  • Authorization: Bearer {{accessToken}}

4. Refresh Token

• Method: POST
• URL: {{base_url}}/auth/refresh
• Body (JSON):

{
  "refreshToken": "{{refreshToken}}"
}

5. Logout

• Method: POST
• URL: {{base_url}}/auth/logout
• Body (JSON):

{
  "refreshToken": "{{refreshToken}}"
}

🧪 Automated Testing Script

Create a test script to verify all functionality:

// test-api.js
const BASE_URL = 'http://localhost:5000/api';

async function testAPI() {
  console.log('🧪 Starting API Tests...\n');
  
  // Test 1: Health Check
  console.log('1️⃣ Testing server health...');
  const health = await fetch('http://localhost:5000/');
  console.log('✅ Server is running:', await health.text());
  
  // Test 2: Register User
  console.log('\n2️⃣ Testing user registration...');
  const registerResponse = await fetch(`${BASE_URL}/auth/register`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      username: 'testuser',
      email: '[email protected]',
      fullname: 'Test User',
      password: 'password123'
    })
  });
  
  if (registerResponse.ok) {
    console.log('✅ User registration successful');
  } else {
    console.log('⚠️ User might already exist');
  }
  
  // Test 3: Login
  console.log('\n3️⃣ Testing user login...');
  const loginResponse = await fetch(`${BASE_URL}/auth/login`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      email: '[email protected]',
      password: 'password123'
    })
  });
  
  const loginData = await loginResponse.json();
  if (loginData.success) {
    console.log('✅ Login successful');
    console.log('📝 Access Token:', loginData.accessToken.substring(0, 30) + '...');
    console.log('🔄 Refresh Token:', loginData.refreshToken.substring(0, 30) + '...');
    
    // Test 4: Protected Route
    console.log('\n4️⃣ Testing protected route...');
    const protectedResponse = await fetch(`${BASE_URL}/rbac-test/user-only`, {
      headers: { 'Authorization': `Bearer ${loginData.accessToken}` }
    });
    
    if (protectedResponse.ok) {
      const protectedData = await protectedResponse.json();
      console.log('✅ Protected route accessed:', protectedData.message);
    }
    
    // Test 5: Token Refresh
    console.log('\n5️⃣ Testing token refresh...');
    const refreshResponse = await fetch(`${BASE_URL}/auth/refresh`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ refreshToken: loginData.refreshToken })
    });
    
    if (refreshResponse.ok) {
      const refreshData = await refreshResponse.json();
      console.log('✅ Token refresh successful');
      console.log('📝 New Access Token:', refreshData.accessToken.substring(0, 30) + '...');
    }
    
    // Test 6: Logout
    console.log('\n6️⃣ Testing logout...');
    const logoutResponse = await fetch(`${BASE_URL}/auth/logout`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ refreshToken: loginData.refreshToken })
    });
    
    if (logoutResponse.ok) {
      console.log('✅ Logout successful');
    }
    
    console.log('\n🎉 All tests completed successfully!');
  } else {
    console.log('❌ Login failed:', loginData.message);
  }
}

testAPI().catch(console.error);

🐛 Troubleshooting

Common Issues:

1. MongoDB Connection Error

   • Ensure MongoDB is running
   • Check MONGO_URI in .env file

2. JWT Secret Error

   • Ensure JWT_SECRET and REFRESH_TOKEN_SECRET are set in .env

3. Port Already in Use

   • Change PORT in .env file
   • Kill existing process: lsof -ti:5000 | xargs kill -9

4. Token Validation Errors

   • Check if tokens are properly formatted
   • Ensure Authorization header includes "Bearer " prefix

Debug Mode:

Add this to your .env file for detailed logging:

NODE_ENV=development
DEBUG=true

📊 Expected Results

✅ All endpoints should return proper responses
✅ Authentication flow should work seamlessly
✅ Refresh token mechanism should function correctly
✅ Logout should invalidate tokens
✅ Protected routes should require valid tokens
✅ Role-based access should work as expected

🎯 Success Criteria

• Server starts without errors
• Database seeding completes successfully
• User registration works
• Login returns both access and refresh tokens
• Protected routes require authentication
• Token refresh works correctly
• Logout invalidates refresh token
• All error cases are handled properly

Happy Testing! 🚀
