What is a primary focus when conducting API testing?

• A. Testing graphical interfaces
• B. Assessing the full functionality of the system
• C. Verifying user interactions with application elements
• D. Testing aesthetic features like fonts and images

Answer: (B)

The primary focus when conducting API testing is to assess the full functionality of the system. API testing is aimed at checking the integration between various software components and ensuring that the application behaves as expected when different inputs and interactions happen through the API. Unlike testing graphical interfaces, which is more concerned with the user interface, API testing evaluates the backend logic and the processing of requests and responses. By focusing on the full functionality of the system, API testing allows testers to verify that all endpoints are functioning correctly, respond with the expected status codes, and return the correct data format. This testing is crucial for identifying issues such as incorrect responses to valid requests, edge cases, and error handling. It ensures that the application can interact with other services, leading to a robust and reliable system. In summary, the emphasis of API testing is on functionality, performance, reliability, and security of the application's interfaces rather than on aesthetic features or user interactions, which are addressed by other forms of testing.
