The difference between white box and black box testing lies in their approach: - White box testing involves testing the internal workings of an application, including code structure, logic, and algorithms. Testers have knowledge of the code and design test cases accordingly. - Black box testing, on the other hand, focuses on testing the software's functionality without any knowledge of the internal code. Testers evaluate inputs and outputs based on requirements. As for which is better, it depends on the context. White box testing is beneficial for identifying logical errors and ensuring code quality, while black box testing is essential for validating user requirements and overall functionality. A combination of both is often the most effective approach to ensure comprehensive testing. read less

What is the disadvantage of black box testing?
Without clear functional specifications, test cases are difficult to implement. It is difficult to execute the test cases because of complex inputs at different stages of testing. Sometimes, the reason for the test failure cannot be detected.
