Software Testing And Quality Assurance Questions
Black box testing and white box testing are two different approaches to software testing.
Black box testing is a testing technique where the tester does not have any knowledge of the internal structure or implementation details of the software being tested. The tester focuses on the functionality and behavior of the software from an end-user perspective. It involves testing the software by providing inputs and observing the outputs, without considering the internal code or logic. Black box testing is primarily used to validate the software against specified requirements and to identify any functional defects or inconsistencies.
On the other hand, white box testing, also known as clear box testing or structural testing, is a testing technique where the tester has complete knowledge of the internal structure, design, and implementation details of the software being tested. The tester examines the internal code, logic, and data flow to ensure that the software functions correctly at a granular level. White box testing focuses on testing individual components, modules, or units of the software to identify any defects or errors in the code. It is primarily used to validate the internal structure and design of the software, ensuring that it meets the required standards and guidelines.
In summary, the main difference between black box testing and white box testing lies in the level of knowledge and focus. Black box testing is performed without any knowledge of the internal structure, while white box testing is performed with complete knowledge of the internal structure. Black box testing focuses on the functionality and behavior of the software, while white box testing focuses on the internal code and logic.
