Regression Testing refers to testing of existing functionality to ensure that recent changes do not adversely affect existing features. For example, when implementing Asset Management, the existing Incident functionality is tested to test use cases such as creating an incident, creating a task, updating incidents, closing tasks, incidents, etc. In addition to UAT Test Scripts, you will want to do a comparison of existing workspaces, existing functionality, and existing features, to ensure existing functionality has not been impacted.
