When do we use White Box Testing & Black Box Testing?

White-box testing is a method of testing in which the internal structure of the software being tested is known to the tester and is used to design the test cases. It is used to test the internal structure and logic of a program, and it is typically done by developers as part of the testing process.

White-box testing is typically used during the development process, as it can be done early on and can help identify and fix issues before the software is released. It can also be used to test specific components or functions of a program to ensure that they are working correctly.

On the other hand, Black box testing is a method of testing in which the internal structure of the software is not known to the tester, and test cases are designed based on the functionality of the software as specified in the requirement documents. It is typically done by testers who do not have access to the source code of the software being tested.

Black-box testing is typically used later in the development process, after the software has been implemented and is ready for testing. It is often used in combination with other testing methods, such as white box testing, to provide a comprehensive testing approach.

Both white-box testing and black-box testing are important methods of testing that can be used to ensure the quality and reliability of software. They are often used in combination to provide a comprehensive testing approach.
