Black-box testing focuses on testing the functionality of a program without knowledge of its internal code structure. Testers only interact with the program's inputs and outputs to verify if it behaves as expected. On the other hand, white-box testing involves testing the internal logic and structure of the program. Testers have access to the code and use this knowledge to design test cases that ensure all paths and conditions within the code are tested. In summary, black-box testing is more focused on the external behavior of the program, while white-box testing is focused on the internal implementation details. **
