What does UAT stand for?
UAT stands for user acceptance testing. It is the phase where the people who will actually use the software check that it does what they need, before it goes live.
It sits after the technical testing. QA has already checked the code does what the specification says. UAT checks whether the specification was right.
Who runs UAT
Not the development team. UAT is run by the people who will use the software day to day, or by the client who commissioned it. That is the whole point. A developer testing their own work checks that it behaves as designed. A user checks whether the design was correct.
In practice that means business users, subject matter experts, sometimes a customer’s own staff. They test against real tasks rather than test cases.
UAT vs QA testing
QA asks “does this work as specified?” and is run by testers against defined cases. It catches defects.
UAT asks “does this solve the problem we had?” and is run by users against real work. It catches misunderstandings, which are more expensive and usually surface later.
Software can pass every QA test and fail UAT completely, because passing QA means the team built what was written down and UAT is where you find out whether what was written down was what the business needed.
The UAT process
- Define what acceptance means. Which tasks must be completable, by whom, without help. Vague criteria produce a sign-off nobody trusts.
- Recruit real users. People who do the job, not people who understand the software.
- Give them tasks, not scripts. “Process a refund for an order placed last month” tells you more than a numbered click sequence.
- Capture what they hit, in context. Screenshot, browser, what they were doing. A report that says “it didn’t work” costs a day to reproduce.
- Decide and sign off. Which issues block release and which are logged for later.
Where UAT usually goes wrong
The most common failure is the report format. Testers who are not technical describe what happened in their own words, and the development team cannot reproduce it. Half the UAT cycle then goes on clarifying rather than fixing.
The second is treating sign-off as the end. UAT catches what a small group notices in a short window under artificial conditions. Real users find different things, at volume, once the software is doing actual work. Teams that close the feedback channel at go-live lose exactly the information that was hardest to get.
The better pattern is to keep the same channel open after release, so acceptance testing becomes the first round of continuous feedback rather than a one-off gate.
How Usersnap supports UAT
Testers report without leaving the software. They point at what is wrong, annotate a screenshot, and Usersnap attaches the browser, operating system, screen size and console errors automatically, so the report arrives reproducible instead of described. Screen recordings cover anything a screenshot cannot show.
Reports land in one place with statuses and assignment, and push to Jira, Linear or Azure DevOps so they enter the workflow the team already uses. The same widget stays in place after go-live, which is what turns a testing round into an ongoing channel.
UAT FAQ
What does UAT stand for in software?
User acceptance testing. The final testing phase, run by the people who will use the software, checking it meets their needs before release.
What does UAT stand for in project management?
The same thing. In project management it is usually the gate before go-live, where the client or business owner formally accepts the delivery.
What is the difference between UAT and QA?
QA verifies the software matches the specification. UAT verifies the specification matched the need. QA finds defects, UAT finds misunderstandings.
Who performs UAT?
End users, business stakeholders or the client. Not the developers who built it, and usually not the QA team who tested it.
