White box testing, also known as clear box testing or structural testing, is a software testing technique that focuses on examining the internal structure and implementation details of a software application. In white box testing, the tester has access to the source code and is aware of the internal workings of the software being tested.
The main objective of white box testing is to ensure that all paths, branches, and conditions within the code are tested thoroughly. It aims to validate the correctness of the code logic, identify any coding errors, and ensure that all statements and functions are executed as intended.
White box testing techniques include statement coverage, branch coverage, path coverage, and condition coverage. These techniques involve designing test cases that exercise different parts of the code, ensuring that all possible scenarios and conditions are tested.
White box testing is typically performed by developers or testers with programming knowledge, as it requires understanding the code structure and implementation details. It is often conducted during the early stages of the software development lifecycle to catch and fix any coding errors or defects before the software is released.
Overall, white box testing plays a crucial role in ensuring the quality and reliability of software applications by thoroughly examining the internal code structure and validating its correctness.
