White Box Testing
White box testing is a software testing methodology that examines the internal structure, design, and implementation of an application's code. It involves analyzing the logic, data flow, and control flow within the software to ensure that all paths and conditions are tested. This approach requires knowledge of the underlying code and is typically performed by developers or testers with programming expertise.
Developers should learn white box testing to identify hidden errors, optimize code performance, and ensure thorough test coverage, especially for critical or complex systems. It is essential during unit testing, integration testing, and when verifying algorithms, as it helps catch bugs early in the development cycle, reducing long-term maintenance costs.
