White box testing allows testers to investigate and validate the inner workings of a software system, including its code, infrastructure, and connections with external systems.
Effective at detecting faults and problems. Thorough testing necessitates knowledge of the internals of the software under test. Allows the detection of concealed faults.
Black Box testing is performed without knowledge of the internal structure of the program or application, whereas White Box testing is performed with knowledge of the internal structure of the program or application.
Statement, branch, and function coverage are the three basic categories of white box testing approaches and methods related to code coverage.
White box testing is a way of reviewing software that examines the underlying structure, design, coding, and inner-workings of the product. This testing method is used by developers to evaluate the flow of inputs and outputs through the program, hence improving usability and design and boosting security.
