What are the prerequisites of Acceptance testing?

There are few basic prerequisites that should be in place before starting Acceptance testing:

As acceptance testing environment is different from Component, integration or system testing so the UAT environment should be ready. Also, all the above-mentioned testing should be completed before starting UAT testing.

Defects with high/medium severity or showstopper bugs shouldn’t exist in the application.

Regression of the application should be completed, this should not result in any major bug, at max cosmetic bugs can be ignored at this level.
