Describe Black-box testing (pick two)

1. Requires programming and implementation knowledge

2. Exhaustive path testing is one of its type of testing technique

3. Exhaustive input testing is one of its type of testing technique

4. Internal structure or design implementation is not known to the tester

The correct answer is: Exhaustive input testing is one of its type of testing technique

Black-box testing is a software testing method that focuses on examining the functionality of an application without knowledge of its internal workings or code structure. This means that the tester interacts with the software purely from an end-user perspective, validating behaviors against requirements and expected outcomes. One of the aspects that make the selection of exhaustive input testing particularly relevant is that it emphasizes validating a wide range of inputs to ensure that the software can handle various scenarios. Exhaustive input testing involves testing all possible input conditions to ensure that the application behaves as expected under numerous variations, which aligns well with the principles of black-box testing. The selection highlights the user-centric perspective of black-box testing, where the tester does not need to understand the code or implementation details. Instead, they assess whether the software functions correctly based on the inputs provided, which is a key characteristic of this testing methodology. On the other hand, aspects that require a thorough understanding of internal structure or programming knowledge are not applicable to black-box testing; instead, aspects related to internal design or exhaustive path testing require intimate knowledge of the system, which is typically associated with white-box testing.
