Suppose you are a manufacturer looking to introduce a new electric kettle. Your product team develops it and releases it in the market without checking to make sure it is not faulty. A customer plugs it in and the kettle malfunctions. The complaints pile up. So what do you do? Before re-launching the kettle, you will make sure to \u201ctest\u201d it.<\/span><\/p>\n

In the same way, web and mobile applications<\/a> need to be tested before deployment to make sure they are error-free and work as expected. Black box and white box testing are the two main types of software testing that prove helpful here.<\/span><\/p>\n

Software testing does not have to be an isolated phase of the software development life cycle. It needs to be done at various stages of SDLC. An app can be tested for accuracy and correctness right from the design and prototyping<\/a> stage up until the moment right before launch.<\/span><\/p>\n

What Is Black Box Testing?<\/span><\/h2>\n

Black box testing refers to a type of software testing process that requires the tester to test an application without possessing any knowledge of the application\u2019s internal structure. The application that is being tested can be thought of as a black box that they cannot see inside. However, they do not go in completely blind.<\/span><\/p>\n

Black box testers are informed about the expected behaviour of the software. Instead of worrying about the technologies that have been used to put together and develop the app, the tester focuses on whether or not the app meets all the requirements listed in the Software Requirements Specification (SRS). With the help of a user interface, they can check the various features in the app and see whether each of those features is performing its designated function(s).<\/span><\/p>\n

Testers are supposed to make sure that the app is carrying out all its functions not just correctly but also efficiently. There may be certain non-functional requirements that need to be met, such as data security or the interface\u2019s ease of use.<\/span><\/p>\n

It seems pretty simple, doesn\u2019t it? Well, it is not! The tester needs to know how to carefully determine what test cases to run based on the specified requirements, and then analyse the outcomes obtained.<\/span><\/p>\n
