Black box and white box testing are both software testing methodologies that help identify defects in an application or software: Black box testing Tests the system from the user's perspective, without knowledge of the internal implementation. This method is good for identifying interface-level bugs. Black box testing is faster to perform than white box testing and doesn't require knowledge of the application's internal implementation. White box testing Analyzes the system's internal coding to uncover structural problems, hidden errors, and problems with specific components. White box testing can help identify bugs at the design level. White box testing requires knowledge of the application's internal workings. Combining black box and white box testing can provide a more comprehensive inspection of an application. This is known as grey box testing. read less
