White-box Testing vs. Black-box Testing

White-box Testing: White-box testing is a software testing technique that focuses on internal structures and workings of the application code. Testers have access to the source code and design documents, allowing them to design test cases based on the code logic. The main goal of white-box testing is to ensure the reliability and completeness of the software code.

Black-box Testing: Black-box testing, on the other hand, is a software testing technique that focuses on testing the functionality of the software without knowing the internal code structure. Testers do not have access to the source code and design details, and they test the software based on its specifications and requirements. The main goal of black-box testing is to validate the software against its functional requirements and ensure that it behaves as expected.

In summary, the key difference between white-box and black-box testing lies in the level of visibility into the internal structures of the software code. White-box testing is code-oriented, while black-box testing focuses on external behavior. Both testing techniques are essential in ensuring the quality and reliability of software applications.
