Black box testing is also known as behavioral testing and is a kind of software testing method. The tests done are usually functional, but sometimes non-functional. Black box testing the testing of an item without the design/structure/implementation being known to the tester.
According to an example of black box testing given by softwaretestingfundamentals.com,
“A tester, without knowledge of the internal structures of a website, tests the web pages by using a browser; providing inputs (clicks, keystrokes) and verifying the outputs against the expected outcome.”
Black box testing is important because:
• Black box testing helps exposing discrepancies in the specifications as the tests are done from a user’s point of view.
• Since the test does not involve structure or design, the tester need not know programming languages.
• The tests are independent of the developers and hence free of bias.
• The tester only has a goal to accomplish, and no guidelines at all about how the goal has to be accomplished.
• This makes the testing process free of any possible discrepancies and biases.
