MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -White box testing is a technique that uses a program’s internal or source code to design different test cases to check the quality of the program. In this technique, the internal structure and implementation of how an application works are known to the tester. You may understand this by a simple example.

Detailed explanation-2: -White-box testing is the detailed investigation of internal logic and structure of the code. White-box testing is also called glass testing or open-box testing. In order to perform white-box testing on an application, a tester needs to know the internal workings of the code.

Detailed explanation-3: -White box testing is an approach that allows testers to inspect and verify the inner workings of a software system-its code, infrastructure, and integrations with external systems.

Detailed explanation-4: -The difference between white box testing and source code review is that you do not channelize knowledge of availability of a vulnerability after reviewing the code in source code review, but in a white box testing you use this knowledge to create a working POC (Proof of Concept).

Detailed explanation-5: -White-box testing can be applied at the unit, integration and system levels of the software testing process. Although traditional testers tended to think of white-box testing as being done at the unit level, it is used for integration and system testing more frequently today.
