| Testing Type | Purpose | Key Benefits |
|---|---|---|
| Integration Testing | Confirms that different modules or external systems work together correctly within the API | Automates tests to ensure internal and external interactions are faultless—crucial for application reliability in systems like microservices architectures |
| End-to-End Testing | Assesses the complete operational flow, imitating real user scenarios | Captures user experience issues not detected at other testing levels, providing a comprehensive check on how the API performs from start to finish |
| Regression Testing | Verifies that new updates or features do not disrupt existing functions | Allows for continuous testing of affected functions after each update, maintaining consistency and reliability throughout development changes |
| Performance Testing | Evaluates how the API copes under stress, checking aspects like response times and resource usage | Helps predict and improve API behavior under peak loads, ensuring performance benchmarks are met |
