What is the primary goal of usability testing?

The primary goal of usability testing is to ensure that the product is user-friendly and meets user needs. This type of testing focuses on the end-user experience, assessing how easily and effectively users can interact with the software. Usability testing involves observing real users as they complete tasks within the application, which provides insights into the user interface, navigation, and overall satisfaction. The findings from this testing can highlight areas where improvements can be made to enhance user experience, ensuring that the final product aligns with user expectations and requirements.

In contrast, the other options focus on different aspects of software quality. For example, evaluating the system's performance under load pertains to performance testing, not usability. Verifying the correct functionality of software components is the domain of functional testing, which checks whether the software behaves as expected. Measuring code quality and maintainability falls under code review and static analysis rather than usability. Each of these aspects is important for the overall quality of the software, but they do not specifically address the user interaction and experience that usability testing aims to optimize.
