User Acceptance Testing is abbreviated as UAT. Here, the user is the client who has hired you to create software for them or customers to whom you will be selling your product. And, acceptance means approval or agreement. Software testing is performed by the client or user to see if the software is approved for release or not. In short, the main purpose of user acceptance testing is to verify that your software meets user needs and business requirements.
Developers are inclined to create a tunnel vision while working on the same apps for longer periods. Everything cannot be evaluated and assessed, particularly the front-facing side of the software. Bad user experience (UX), errors and post-release bugs are some other problems solved by the UAT. Perhaps, these bugs cannot be detected by the other testing methodologies. However, they become prominent in features flow and app design. Resolving these defects before app release will decrease primary negative reviews and impressions of your software.
