What does white box testing allow the tester to do?

White box testing allows the tester to understand and evaluate the internal mechanisms of the software being tested. This approach provides insight into the internal structure, design, and implementation of the code, enabling the tester to verify that the internal operations work as intended. By having access to the code, the tester can create test cases that specifically target various paths and logic conditions, ensuring that all components function correctly and that any potential flaws are identified. This method contrasts with black box testing, where the tester focuses solely on inputs and outputs without any knowledge of the internal workings.
