What is "system integration testing"?

• A. Testing that evaluates individual components separately
• B. Testing that ensures multiple components function together as intended
• C. Testing that focuses on user interface elements only
• D. Testing conducted exclusively by developers

Answer: (B)

System integration testing is focused on ensuring that multiple components or subsystems of a system work together as intended. This type of testing assesses the interactions and data flow between integrated parts, verifying that they operate correctly when combined. The aim is to identify any issues that arise from the interactions of components, which may not be apparent when testing components in isolation. By conducting system integration testing, teams can confirm that the overall system meets its requirements and functions cohesively, which is critical for the success of complex projects. In contrast, the other options describe different aspects of testing that do not capture the essence of system integration testing. For instance, testing individual components separately would not address how those components interact in a larger system. Focusing solely on user interface elements neglects the backend interactions that can affect overall system functionality. Lastly, conducting testing exclusively by developers doesn't encompass the collaborative aspect of integration testing, which often involves various stakeholders to ensure that all integrated components perform well together.
