In White Box Testing, what is the primary emphasis?

Testing outputs without knowledge of code
Ensuring user interfaces are intuitive
Examining each line of code
Focusing on the final product's usability

The correct answer is: Examining each line of code

In White Box Testing, the primary emphasis is on examining each line of code. This testing technique involves a comprehensive understanding of the internal workings of the application, allowing testers to verify the logic, control flow, and structure of the code. Testers can create test cases based on specific paths, conditions, and branches within the code, ensuring that all code paths are tested for correctness. By focusing on the internal structure, White Box Testing helps in identifying hidden errors, optimizing the code, and ensuring that all possible execution paths are validated. This level of scrutiny is essential for achieving high code quality and reliability, which is particularly crucial in complex software systems where even minor defects can lead to significant issues.
