What is black-box testing in software engineering?
a) Testing without knowledge of the internal code structure
b) Testing the performance of the software
c) Testing individual components of the system
d) Testing the security of the system
Answer:
a) Testing without knowledge of the internal code structure
Explanation:
Black-box testing is a software testing method where the tester evaluates the system’s functionality without having knowledge of its internal code structure. The tester interacts with the system from the user’s perspective, focusing on inputs and expected outputs.
This type of testing is used to validate whether the software meets its functional requirements and behaves as expected under various conditions. It is commonly used for system testing, acceptance testing, and usability testing.
Since the tester does not need to understand the internal workings of the software, black-box testing is often used to simulate how end-users will interact with the system.
