What is White Box Testing?

White Box Testing is a method where the tester knows the internal structure, design, and code of the software, also known as Glass Box Testing or Clear Box Testing. This allows designing test cases based on this understanding, focusing on individual units in unit testing to ensure code functions correctly.

This method is essential for identifying hidden errors, broken paths, or missing functionalities in the software code by examining its internal structure. Integration Testing checks how individual units work together, ensuring the software functions correctly under various conditions.

White Box Testing verifies the software's correctness, completeness, and reliability by evaluating its internal structure, making it an indispensable testing technique in software development.
