Black Box Software Testing

Black box testing is the Software testing method which is used to test the software without knowing the internal structure of code or program. Most likely this testing method is what most of tester actual perform and used the majority in the practical life.

Basically software under test is called as "Black-Box", we are treating this as black box & without checking internal structure of software we test the software. All testing is done as customer's point of view and tester is only aware of what is software is supposed to do but how these requests are processing by software is not aware. While testing tester is knowing about the input and expected outputs of the software and they do not aware of how the software or application actually processing the input requests & giving the outputs. Tester only passes valid as well as invalid inputs & determines the correct expected outputs. All the test cases to test using such method are calculated based on requirements & specifications document.

Black box testing is a software testing technique that examines software functionality without peering into its internal structure or coding. An explicit requirement specification provided by the customer serves as the main source of black box testing.

In this method, our team selects a function and provides an input value to examine its functionality, and then determines whether or not the process produces the expected output.

Before moving on to the following function, our test team communicates the results to the development team. The part passes testing if it returns correct results; otherwise, it fails. After testing all aspects, the product is returned to the development team for correction if there are
significant issues.
