Certified Associate in Software Testing (CAST) Practice Test

What type of testing validates the internal logic of a system to develop test cases?

1. Structural Testing

2. Functional Testing

3. Non-Functional Testing

4. Compliance Testing

The correct answer is: Structural Testing

Structural testing, also known as white-box testing, focuses on validating the internal logic and structure of the software system. This type of testing involves examining the code, algorithms, and internal workflows that drive the software's functionalities. By having insight into the internal workings, testers can create test cases that ensure each part of the application operates as intended. This approach allows testers to identify potential weaknesses within the code, ensuring that the logic, data flow, and control flow are functioning correctly. Testers can create exhaustive test cases based on decision paths, loops, and branches in the code. This level of detail is crucial for uncovering hidden errors that may not be obvious through external testing approaches. Functional testing, on the other hand, revolves around validating the software against requirements, ensuring it behaves as expected from the user's perspective without involving internal code structures. Non-functional testing assesses aspects like performance and usability rather than internal logic. Compliance testing checks adherence to standards and policies, rather than focusing on the internal workings of the software.
