MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Black box testing is a software testing methodology in which the tester analyzes the functionality of an application without a thorough knowledge of its internal design. Conversely, in white box testing, the tester is knowledgeable of the internal design of the application and analyzes it during testing.

Detailed explanation-2: -Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.

Detailed explanation-3: -Mainly, there are three types of black-box testing: functional testing, Non-Functional testing, and Regression testing. The types of white box testing are – Path testing, Loop testing, and Condition testing.

Detailed explanation-4: -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-5: -Description: In black box testing, the structure of the program is not taken into consideration. It takes into account functionality of the application only. It is also called functional testing. Tester is mainly concerned with the validation of the output rather than how the output is produced.
