What is system testing primarily concerned with?

System testing is primarily concerned with evaluating the complete system as a unified entity. This phase of testing aims to ensure that the integrated components of the software work together as intended, highlighting the collective behavior of the application. It verifies that all functional and non-functional requirements are met when the system operates as a whole, addressing interactions between subsystems and ensuring overall system stability and performance.

By focusing on the complete system, testers can identify issues that may not be apparent when examining individual units or subsystems in isolation. This collaborative evaluation is critical for understanding how the different parts of the system interact and for ensuring that the final product is robust and capable of handling real-world scenarios.

In contrast, testing individual subsystems separately would fall under unit testing or integration testing rather than system testing, while performing data entry procedures and conducting user experience surveys are more related to usability testing and validation of workflows within the application.
