White Box Testing, also known as clear box or structural testing, is a software testing method where the tester has complete knowledge of the internal workings of the application. This approach involves examining the code, architecture, and design to validate the functionality and ensure all internal operations align with the intended behavior. Unlike black box testing, which focuses on inputs and outputs, white box testing dives into the logic, decision-making, and flow of the code. It is used to identify vulnerabilities, optimize code paths, and ensure thorough coverage of all code branches. Typically, developers perform this testing during unit and integration testing phases.
