Integration Testing

Integration Testing

Tests how multiple components work together.

Instructions

When creating integration tests:

1. Identify integration points

   • API endpoints
   • Database interactions
   • Service communication
   • External dependencies

2. Set up test environment

   • Use test databases
   • Mock external services
   • Clean state between tests

3. Write test scenarios

   #[tokio::test]
   async fn test_user_registration_flow() {
       // Setup
       let app = spawn_app().await;
       
       // Act
       let response = app.post_register(json!({
           "email": "test@example.com",
           "password": "password123"
       })).await;
       
       // Assert
       assert!(response.status().is_success());
   }
   

Best Practices

• Test realistic user scenarios
• Use actual databases when possible
• Clean up resources after tests
• Run in isolated environments
