Which type of software testing focuses on the internal structure and logic of the code rather than its functionality?

White Box Testing, also known as clear-box or structural testing, assesses the internal workings of an application. 1. Code-Centric Approach: Testers examine source code to identify logical flaws, structural issues, or performance bottlenecks. 2. Techniques: Common methods include statement coverage, branch coverage, and path testing, which ensure all code paths are tested. 3. Developer-Friendly: Typically performed by developers or testers with programming knowledge, White Box Testing complements Black Box Testing by verifying internal code quality. 4. Use Cases: It is particularly useful for detecting hidden errors, optimizing code efficiency, and ensuring compliance with standards. This type of testing ensures the software is robust at the code level, minimizing runtime failures. Why Other Options Are Incorrect: • A) Black Box Testing: Focuses on testing functionality without considering the internal code structure. • B) Regression Testing: Ensures that recent code changes have not adversely affected existing functionality. • C) Unit Testing: Validates individual components but does not necessarily require internal code analysis. • E) User Acceptance Testing (UAT): Validates the software against user expectations, focusing on functionality and usability rather than code structure.
