Question

In which of the following tests does the tester not need to have prior knowledge of the system's internal design or features?

a) Red box testing
b) White box testing
c) Black box testing
d) Gray box testing

Answer 1

Black box testing is the method in which the tester does not need prior knowledge of the system’s internal design or features. It assesses the functionality of an application based on specifications and requirements.

Step-by-step explanation:

In the context of software testing, the tester does not need to have prior knowledge of the system's internal design or features during Black box testing. This type of testing focuses on examining the functionality of an application without peering into its internal structures or workings. Test cases are built around specifications and requirements, stating what the system does, not how it does it.

On the other hand, White box testing requires knowledge of the internal workings of the application, as it tests the code directly. Gray box testing is somewhat in between, where testers have partial knowledge of internal structures, typically used in penetration testing and security audits. There is no widely recognized technique called Red box testing in the software testing framework.
