Black Box Testing is a software testing method in which the functionalities of software applications are tested without having knowledge of internal code structure, implementation details and internal paths. Black Box Testing mainly focuses on input and output of software applications and it is entirely based on software requirements and specifications. It is also known as Behavioral Testing.
The above Black-Box can be any software system you want to test. For Example, an operating system like Windows, a website like Google, a database like Oracle or even your own custom application. Under Black Box Testing, you can test these applications by just focusing on the inputs and outputs without knowing their internal code implementation. Consider the following video tutorial-

Here are the generic steps followed to carry out any type of Black Box Testing.
There are many types of Black Box Testing but the following are the prominent ones -
Tools used for Black box testing largely depends on the type of black box testing you are doing.
Following are the prominent Test Strategy amongst the many used in Black box Testing
Black Box Testing | White Box Testing |
---|---|
the main focus of black box testing is on the validation of your functional requirements. | White Box Testing (Unit Testing) validates internal structure and working of your software code |
Black box testing gives abstraction from code and focuses on testing effort on the software system behavior. | To conduct White Box Testing, knowledge of underlying programming language is essential. Current day software systems use a variety of programming languages and technologies and its not possible to know all of them. |
Black box testing facilitates testing communication amongst modules | White box testing does not facilitate testing communication amongst modules |
Black box testing has its own life cycle called Software Testing Life Cycle (STLC) and it is relative to every stage of Software Development Life Cycle of Software Engineering.
