What is validated through user acceptance testing?

User acceptance testing (UAT) is primarily focused on validating that the system meets the needs and expectations of its end users in real-world scenarios. This type of testing is conducted by the actual users of the system to ensure that the functionality aligns with their daily operational tasks and requirements. During UAT, users assess whether the system works as intended, is user-friendly, and whether it effectively supports their workflows.

When it comes to daily operations, UAT tests specific functions to ensure they perform correctly within the context of everyday use. This includes validating business processes, workflows, and any features or tools that users interact with regularly. Successfully passing UAT means that the system is ready for deployment, as it has demonstrated that it functions correctly in a way that benefits the users’ daily work scenarios.

While the other options involve important aspects of system validation, they are typically addressed through different phases of the deployment process. For example, system upgrade processes, integration of third-party tools, and data migration accuracy are aspects that might be validated through other testing methodologies, such as system testing, integration testing, or specific data validation checks. These processes are essential but do not directly focus on user interaction and usability in the way that UAT does.
