What does API testing primarily assess?

• A. Security of the application only
• B. Functionality, reliability, performance, and security
• C. Only the performance of the application
• D. User interface consistency

Answer: (B)

API testing primarily assesses the functionality, reliability, performance, and security of an application. This multifaceted approach ensures that the various components of the API are working as intended across different scenarios and workloads. Functionality testing verifies that the API responds correctly to various requests, including how it handles valid and invalid inputs. Reliability testing ensures that the API can consistently deliver the expected outcomes over time. Performance testing evaluates how the API behaves under different loads and stress conditions, measuring response times and throughput. Lastly, security testing looks for vulnerabilities and checks that data protection measures are in place to guard against unauthorized access. The comprehensive nature of B captures the essential aspects of what API testing entails, making it the most accurate answer. Other choices focus too narrowly on only one aspect, like security or performance, while API testing encompasses a broader range of criteria.
