What does white box testing primarily focus on?

White box testing is a software testing method that emphasizes examining the internal workings of an application. It allows testers to understand the underlying logic and structure of the code. This approach involves testing individual functions, paths, and logic conditions within the codebase to ensure that they behave as expected.

By focusing on the internal logic, white box testing aims to verify the correctness of the implementation and identify issues like logical errors or vulnerabilities that may not be evident through external testing methods. It is often performed by developers who have a deep understanding of the code, which enables them to create test cases that thoroughly cover the code's functionality.

Other options, such as user experience, end-user feedback, and code aesthetics, although important aspects of software development and evaluation, do not pertain to the core focus of white box testing, which is specifically concerned with the code's internal mechanics and how it operates.
