What type of test evaluates how user-friendly the interface and features are?

The correct choice focuses on assessing how effectively users can interact with a system, which is precisely the aim of a usability test. This type of test is designed to evaluate the user interface and features of a software application to ensure that they are intuitive, easy to navigate, and conducive to a positive user experience. During usability testing, real users perform specific tasks while observers note any difficulties or challenges encountered, providing valuable insights into how to improve the overall user experience.

In contrast, the other types of tests have different objectives. Performance tests are concerned with measuring how well a system operates under various conditions, often focusing on speed, responsiveness, and stability. Compatibility tests check whether software can run on different devices or operating systems, ensuring that it functions as intended across various environments. Integration tests evaluate how well different components of a system work together, ensuring that combined parts of the software function seamlessly. These distinct aims highlight why usability testing is the most relevant choice for evaluating user-friendliness.
