What is the main objective of system testing?

The main objective of system testing is to ensure the system works correctly in the intended environments. This involves comprehensive evaluation of the entire system’s functionality, performance, security, and compatibility, verifying that it meets specified requirements under various conditions before it is deployed or used by the end-users. This rigorous testing phase aims to identify any defects or issues so they can be resolved, ensuring a smooth operation in real-world scenarios.

A focus on this objective helps instill confidence that the system will perform as expected in its future operational environment, fulfilling both business and user expectations effectively.
