UAT vs Regression Testing?
UAT is the acceptance test. It is performed from the perspective of users. So the focus of UAT is that whether the software product meet the requirements of the users, or the business requirement document. This is important so that we will know that we are delivering a right product for our customers. E.G. Facebook. Whether the “like” function is working as expected.
Regression testing is always conducted after a new features has been deployed. We need to check if the existing functions have been effected or not because of the new features. E.G. Facebook. Previously we have the “Like” function, but after that the developers has deployed a new function, say “dislike”. We need to check after the “dislike” function has been applied, whether the old “like” function is still working properly.
