Software Quality Assurance Practice Exam

What type of test is classified as a module test?

1. Functionality

2. White-box

3. Regression

4. Black-box

The correct answer is: White-box

Module testing, often referred to as unit testing, focuses on verifying each component or module of the software independently to ensure it functions correctly. It is typically conducted by developers during the development phase and involves testing the internal logic and structure of the code. White-box testing fits this description perfectly, as it requires a detailed knowledge of the internal workings of the module being tested. Testers write test cases based on the code structure, logic, and flow, allowing them to evaluate individual functions or methods. This approach allows for thorough examination of conditions, branches, and paths within the code, making it effective for identifying logical errors and ensuring that the module behaves as intended under various scenarios. On the other hand, black-box testing, functionality testing, and regression testing focus on different aspects of software quality. Black-box testing evaluates the functionality of the system without knowledge of its internal workings, while functionality testing generally assesses whether the software behaves according to requirements, and regression testing ensures that recent changes haven't adversely impacted existing functionalities. While all types of testing are crucial to a comprehensive quality assurance strategy, only white-box testing specifically aligns with the objectives of module testing and the understanding of code structure and logic.
