suresh Black box testing and white box testing are two fundamental approaches in functional testing that differ in their testing strategies.
Black box testing examines the functionality of a system without considering its internal code structure or logic. This method focuses on validating the inputs and outputs of the software to ensure that it behaves correctly based on specified requirements.
White box testing, on the other hand, involves testing the internal code structure, logic, and paths within the software. This approach is also known as structural or glass-box testing, as it requires knowledge of the internal workings of the system to design test cases and assess the code's coverage.
In summary, black box testing focuses on external behavior and user perspectives, while white box testing is concerned with the internal code and system structure.
Functional testing teams should carefully consider when to apply black box or white box testing based on the project requirements and goals to ensure comprehensive test coverage and software quality.
