Which of the following comparisons of component testing and system testing are TRUE?

The correct response accurately compares the methodologies behind component testing and system testing in terms of their sources for test case development. In component testing, test cases are indeed derived from component specifications, which detail the expected behavior and functionalities of individual software modules or components. This testing is focused primarily on verifying that these components work as intended in isolation, ensuring that they meet their design specifications.

In contrast, for system testing, test cases are created based on requirement specifications, which outline the overall expected behavior of the system as a whole, including both system functionalities and performance criteria. This comprehensive approach ensures that all aspects of the system work together correctly and meet user expectations.

Understanding the difference between the inputs for test case development in each type of testing helps highlight their distinct purposes: component testing ensures that individual parts function correctly, while system testing ensures that the integrated system fulfills broader requirements. This fundamental distinction is key to grasping the roles that both types of testing play in ensuring software quality.
