+# GitHub Actions Setup Guide for Splitwiser Backend Tests
+
+This guide covers everything you need to set up to run the backend tests successfully in GitHub Actions.
+
+## 🔧 Required Setup
+
+### 1. **MongoDB Configuration**
+**Current Status**: ✅ **Already Handled**
+- Tests use `mongomock` (in-memory MongoDB simulation)
+- No real MongoDB connection needed for tests
+- No additional setup required
+
+### 2. **Firebase Credentials** 
+**Status**: ✅ **Already Handled**
+- Firebase is mocked in tests using `@pytest.fixture`
+- No real Firebase credentials needed for tests
+- Tests will run without Firebase configuration
+
+### 3. **Environment Variables**
+**Status**: ✅ **Configured**
+- Environment variables are set in the GitHub workflow
+- Default test values provided for missing secrets
+
+## 🚀 Setup Instructions
+
+### Step 1: GitHub Repository Secrets (OPTIONAL)
+
+You can add these secrets to your GitHub repository for production-like testing:
+`Settings` → `Secrets and variables` → `Actions`
+
+#### Optional Secrets (Tests will work without these):
+```bash
+# JWT Configuration (optional - defaults provided)
+SECRET_KEY=your-super-secret-jwt-key-for-testing-32chars-min
+
+# Firebase (optional - mocked in tests)
+FIREBASE_PROJECT_ID=your-project-id
+FIREBASE_TYPE=service_account
+FIREBASE_PRIVATE_KEY_ID=your-private-key-id
+FIREBASE_PRIVATE_KEY=your-private-key
+FIREBASE_CLIENT_EMAIL=your-client-email
+FIREBASE_CLIENT_ID=your-client-id
+FIREBASE_AUTH_URI=https://accounts.google.com/o/oauth2/auth
+FIREBASE_TOKEN_URI=https://oauth2.googleapis.com/token
+FIREBASE_AUTH_PROVIDER_X509_CERT_URL=https://www.googleapis.com/oauth2/v1/certs
+FIREBASE_CLIENT_X509_CERT_URL=your-client-cert-url
+```
+
+### Step 2: Workflow Configuration ✅ DONE
+
+The GitHub workflow has been updated to:
+- Set required environment variables with defaults
+- Configure proper Python path
+- Run tests with verbose output
+- Handle missing secrets gracefully
+
+### Step 3: Test Configuration ✅ DONE
+
+The following files have been configured:
+
+#### `pytest.ini`
+- Set up test discovery paths
+- Configure test markers
+- Set up environment file loading
+
+#### `tests/.env.test`
+- Default test environment variables
+- Mock Firebase credentials
+- Test database configuration
+
+#### `tests/conftest.py`
+- Firebase mocking fixtures
+- Environment variable setup
+- Database mocking with mongomock
+
+## 🏃‍♂️ Running Tests
+
+### Locally
+```bash
+# Navigate to backend directory
+cd backend
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Run all tests
+pytest
+
+# Run auth tests only
+pytest tests/auth/ -v
+
+# Run with coverage
+pytest tests/auth/ --cov=app.auth
+```
+
+### In GitHub Actions
+Tests will run automatically when:
+- You push to `main` branch
+- You create a pull request to `main` or `feature/auth-service-workflow`
+- You modify files in `backend/` directory
+
+## 🔍 What's Tested
+
+### ✅ Mock Dependencies
+- **MongoDB**: Uses `mongomock` for in-memory database
+- **Firebase**: Mocked using pytest fixtures
+- **JWT**: Uses test secret keys
+- **External APIs**: All mocked
+
+### ✅ Test Coverage
+- All 7 auth endpoints
+- Service layer methods
+- Error handling
+- Security validations
+- Integration flows
+
+## 🚨 Troubleshooting
+
+### Common Issues and Solutions:
+
+#### 1. **Import Errors**
+```bash
+ModuleNotFoundError: No module named 'app'
+```
+**Solution**: ✅ Fixed with proper `PYTHONPATH` configuration
+
+#### 2. **Firebase Initialization Errors**
+```bash
+Firebase app initialization failed
+```
+**Solution**: ✅ Fixed with Firebase mocking fixtures
+
+#### 3. **Database Connection Errors**
+```bash
+pymongo.errors.ServerSelectionTimeoutError
+```
+**Solution**: ✅ Fixed with mongomock usage
+
+#### 4. **Environment Variable Errors**
+```bash
+KeyError: 'SECRET_KEY'
+```
+**Solution**: ✅ Fixed with default values in workflow
+
+## 📊 Test Results
+
+When tests run successfully, you'll see:
+- ✅ All test files discovered
+- ✅ All auth endpoints tested
+- ✅ Service methods validated
+- ✅ Edge cases covered
+- ✅ Security tests passed
+
+Example output:
+```
+tests/auth/test_auth_routes.py::test_signup_with_email_success PASSED
+tests/auth/test_auth_routes.py::test_login_with_email_success PASSED
+tests/auth/test_auth_routes.py::test_refresh_token_success PASSED
+... (all tests)
+
+====== 50+ tests passed ======
+```
+
+## 🎯 Next Steps
+
+### For Production Deployment:
+1. **Set up real MongoDB** connection
+2. **Configure Firebase** with production credentials
+3. **Set production JWT secrets**
+4. **Configure CORS** for your frontend domain
+5. **Set up monitoring** and logging
+
+### For Development:
+1. **Run tests locally** to verify setup
+2. **Add new test cases** as you develop features
+3. **Monitor test coverage** with coverage reports
+4. **Keep dependencies updated**
+
+## 📝 Summary
+
+**Status**: ✅ **READY TO RUN**
+
+Your tests are now configured to run in GitHub Actions without requiring any additional setup. The workflow will:
+
+1. ✅ Install Python and dependencies
+2. ✅ Set up test environment with defaults
+3. ✅ Mock external dependencies (Firebase, MongoDB)
+4. ✅ Run comprehensive test suite
+5. ✅ Report results and failures
+
+**No additional secrets or external services required!**
