What is "system integration testing" aimed at?

• B. Ensuring various system components work together seamlessly
• C. Evaluating the usability of the system by end-users
• D. Conducting market research on system features

Answer: (B)

System integration testing is specifically aimed at ensuring that various system components work together seamlessly. This involves verifying that the interactions and interfaces between different subsystems or components function correctly as intended. The purpose is to identify any issues that may arise when different parts of the system are combined, which might not be detectable when testing the individual components separately.

This type of testing is critical because a system often consists of multiple integrated parts that need to collaborate to deliver the desired functionality. If integration issues are present, they can lead to system failures, which may not become apparent until the pieces are put together in a real-world scenario. Thus, integrating and validating functionality across components is essential for reliability and performance.

Focusing on the other options, verifying the performance of individual components pertains more to component or unit testing rather than integration testing. Evaluating usability by end-users is related to user acceptance testing, not integration testing. Conducting market research on system features does not directly relate to testing but instead focuses on understanding user needs and market demand.
