True or False: In white-box testing, the tester is not concerned about the internal behavior and structure of a program.

1. True

2. False

3. Only in black-box testing

4. Only in system testing

The correct answer is: False

In white-box testing, the tester is indeed concerned about the internal behavior and structure of a program. This testing method involves understanding the internal logic, code structure, and workings of the application being tested. The goal is to ensure that the code behaves as expected, and that all pathways through the code function correctly. By analyzing the source code, the tester can create test cases that specifically target individual functions, branches, and loops to thoroughly check for errors and verify that all parts of the code are executed under various conditions. This level of scrutiny enables the identification of potential issues that could be missed in other testing methods, such as black-box testing, where the focus is solely on the functionality and output of the application without any consideration of its internal mechanisms. Thus, the statement is false; internal concerns are central to white-box testing.
