White Box Testing
In this tutorial, let’s learn about White box testing. White box testing is a software testing technique that examines the internal structure, source code, program logic, and workings of an application or system. White-box testing is a dynamic testing technique. Dynamic testing involves executing the Application Under Test. (AUT) The other names of white box testing are as follows:
- Glass box testing
- Clear box testing
- Open box testing
- Path driven testing
- Logic driven testing
- Structural testing
White Box Testing
White Box testing is based on the inner working of an application.
In most organizations, developers or testers with programming knowledge usually perform this type of testing. The tester has access to the source code of the software application and has knowledge of its internal workings. The tester uses this knowledge to design white box test cases that will exercise specific paths or conditions within the code to ensure that it is functioning as intended.

Advantages of White Box Testing:
Some advantages of white box testing are as follows:
- Forces test developers to reason carefully about implementation.
- Reveal errors in “hidden” code.
- Spots the dead code or other issues with respect to best programming practices.
Disadvantages of White Box Testing:
Some disadvantages of White box testing are as follows:
- White box testing is expensive as one has to spend both time and money to perform it.
- The testing team should have in-depth knowledge of the programming language necessary to perform white box testing.
White box testing is useful for detecting defects such as coding errors, logical errors, and security vulnerabilities that may be missed by other testing techniques.
