Black Box Testing is a software testing method which tests the functionality of a software component or software without examine the internal structure or internal coding of the software.

The testers think the software component as a black box and they only concentrate on the system functionalities. Testers will only focus on the relationship between the inputs and the corresponding outputs.

During this process, finding of any difference between the expected outputs (The output should be produced by the software) and the outputs produced during the block box testing will consider as a problem with the software being developed.

Black-box testing also termed as Functional Testing and Behavioral Testing. It’s also capable of applying to every level of software testing such as Unit, Integration, System and Acceptance Testing.

Advantages of black box testing

The testers do not need to have the knowledge in internal application structure and programming

This method is also reliable when we need to test a large software component or software

Since the black box testing method does not involve any technical or programming knowledge, end users can also participate in the software testing process and it will help them to be familiar with the software at the earliest.
