Final answer:
The question is about User Acceptance Testing (UAT) in software development, where users test the application based on selected metadata groups, each requiring specific user profiles to conduct the testing effectively.
Step-by-step explanation:
The question pertains to User Acceptance Testing (UAT), which is a phase of software development where the intended users test the software to ensure it can handle required tasks in real-world scenarios, according to the specifications. In this context, different users are supposed to perform manual testing based on the metadata group selected. This implies that there are different groups or categories of metadata that would dictate which users would be suitable for testing specific aspects of the application. The groups mentioned (Promotion Record, Metadata Grid, User Story Selections, Connection Behavior) are likely part of the application's features or data structure that need to be tested. These groups might have different properties or requirements that necessitate distinct user profiles for effective testing.
