What is White Box Testing?

White Box Testing, also known as Clear Box Testing or Structural Testing, is a software testing technique that examines the internal structure or workings of an application's code to ensure that all code paths are tested and executed properly. This technique is used to validate the correctness of the code and to ensure that the software performs as expected under various conditions.

In White Box Testing, the tester has access to the application's source code and can use this knowledge to design test cases that exercise specific code segments or code paths. The goal is to achieve maximum code coverage and to ensure that all statements, functions, and branches in the code are executed at least once.

The main objective of White Box Testing is to verify that the code is written correctly and to identify any errors or defects that may be hidden in the code. This technique can also help in improving the maintainability of the code, as it enables the testers to identify any code that is difficult to maintain or modify.

Some of the common techniques used in White Box Testing include statement coverage, branch coverage, path coverage, and decision coverage. These techniques involve executing the code in different ways to ensure that all code paths are tested thoroughly.

White Box Testing is commonly used in conjunction with other testing techniques such as Black Box Testing and Gray Box Testing to provide comprehensive testing coverage for the software application.
