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

The selection that states test cases for component testing are derived from component specifications, while those for system testing come from requirement specifications is accurate because it highlights the distinct sources of information used to create test cases in both types of testing. In component testing, which focuses on individual software modules or components, the test cases are created based on the specifications that define the behavior and expected outputs of these components. This ensures that the module performs as intended and meets the specified criteria.

On the other hand, system testing is conducted on the entire system as a whole, assessing its compliance with the overarching requirements. Therefore, the test cases for system testing stem from requirement specifications, which outline what the software needs to achieve and include functional and non-functional requirements. By deriving test cases from requirement specifications, system testing is able to ensure that the system meets all user needs, expectations, and performance criteria as a fully integrated product.

This distinction explains the importance of accurate requirements and specifications in guiding the testing process for both components and the complete system, thereby ensuring comprehensive quality assurance.
