Which of the following is true regarding the logic analysis of a module?

1. White-box methods are used for logic analysis

2. Black-box methods are sufficient for logic analysis

3. Only heuristics should be used in module logic analysis

4. Logic analysis does not require any specific testing methods

The correct answer is: White-box methods are used for logic analysis

The statement that white-box methods are used for logic analysis is true because white-box testing focuses on the internal workings of a system. In the context of logic analysis, this approach allows testers to examine the code, control flow, and the logical structure of the module being tested. By using white-box techniques, testers can ensure that all paths through the logic are executed and that the module behaves as intended under different conditions. White-box methods provide insights into the interactions between different components of the module and help identify logical errors that may not be evident from an external viewpoint. These methods typically include code reviews, static analysis, and testing techniques like path, branch, and statement coverage. They allow for a more thorough examination of the module's logic, ensuring that the implementation adheres to the specified requirements and handles edge cases properly. In contrast, relying solely on black-box methods would limit the analysis to the module's inputs and outputs without examining its internal structure, which may lead to undetected logical issues. Furthermore, while heuristics can aid in analyzing logic, they should not be the only method applied in a comprehensive analysis. Lastly, suggesting that logic analysis does not require specific testing methods overlooks the fact that various methods, particularly white-box testing methods, are crucial
