What comes to your mind when you hear the term Black box, specifically concerning testing? Well, it is something that is not very common to listen to but remains an essential form of software testing. It is a software testing technique to examine the functioning of software from an external outlook without digging deeper into its code. The best thing about Black box testing is that it can be applied to all levels of testing ( Unit, integration, system, and acceptance).
Anybody with minimum or no coding language can perform Black box testing of a software product, software testers with no coding language can also do it.
