What is White Box Testing?

White box testing also known as transparent box testing, clear box testing, glass box testing, or structural testing, is a software testing method in which the internal structure and implementation of the software being tested are known and used as the basis for designing the test cases. It involves testing the software at the code level and requires a deep understanding of the code and the design of the software.

In white-box testing, the tester is able to see the internal workings of the software and has access to the source code, so they can design test cases that thoroughly test the different code paths and ensure that the software is working correctly. This type of testing is typically done by developers during the development process to ensure that the code is functioning as intended, but it can also be done by independent testers as part of the quality assurance process.

White-box testing is an important part of the software testing process because it helps to uncover defects and vulnerabilities that may not be discovered through other types of testing. It is particularly useful for identifying issues with code logic, error handling, and security vulnerabilities.

However, it is important to note that white box testing is only one aspect of the testing process and should be used in conjunction with other types of testing, such as black box testing and integration testing, to provide a comprehensive assessment of the software's quality and reliability.
