Black Box Testing


In this tutorial, we will learn about the black box testing. This testing type is named so because the software program, from the eyes of the tester, is like a black box, inside which the tester cannot see anything. It is also known as Opaque Testing or Behavioral Testing.

Black Box Testing

Black box testing is a software testing technique or method in which the testers do not know the internal working details like structure, design, and implementation code of the tested system.

Given that the internal workings of the software are not visible or opaque to the tester, the term Opaque Testing is sometimes used for this testing.

It is called Behavioral Testing because the focus is on the external behavior of the software rather than the internal logic or structure. Testers check whether the software behaves as expected based on specified requirements.

In this testing, the tester interacts with the software as an end-user, providing the test inputs and observing the test outputs without knowing how the software works internally. The tester only knows what the software should do, not how it does it.

Black Box Testing Disadvantages

Some of the disadvantages of Black box testing are as follows:

Black box testing is essential in software testing, as it helps to ensure that the software product meets the end user’s needs and expectations. By performing this testing, testers can identify and report any functional or non-functional issues in the software before they affect the end users.
