What does white box testing primarily address?

White box testing primarily focuses on the internal workings of a system. This approach allows testers to delve into the code structure, algorithms, and logic used within the system rather than examining the external outputs or behavior. By analyzing the internal components, testers can verify the correctness of the code, uncover hidden errors, and ensure that the logic is functioning as intended.

Moreover, white box testing enables a thorough examination of specific code paths and conditions, which can lead to identifying potential vulnerabilities or inefficiencies within the code. Consequently, this method is essential for ensuring that the software operates correctly at a fundamental level, which contributes to overall system reliability and performance.

Understanding white box testing's emphasis on the internal logic elucidates its role in software development and quality assurance. This is distinct from other testing methodologies, like black box testing, which examines functionality without regard to the underlying code.
