What is User Acceptance Testing(UAT)

 

UAT is a testing procedure which involves clients/end users to validate the business workflow from start to finish. Clients/end users affirm the item against their needs and problems.

UAT procedure includes, extensive preparation and evaluation to calculate anticipated dangers and make an informed choice. Quality is not an crash, it's the outcome of thorough testing. For sure some compromises about quality are inevitable, due to time and resource constraints.

Currently a note on UAT or Beta testing.

Just as I'm concerned User Acceptance Testing will be the same as proper Beta Testing. Both imply: showing a potentially finished merchandise to real life users and getting their answer.

The distinction is: UAT tends to take place in business environments where customers work for the organization and will need to use the program. Beta testing tends to happen in applications vendor environments also it means showing the applications, even giving it to, potential users away from the business.

UAT and Beta testing can only truly be carried out by USERS (yes I am shouting). If you have professional testers performing it then it's in effect a kind of System Testing.

This means UAT/Beta cannot be automated since it is all about getting real lifestyle users into consumer the applications and get their feedback. If users assign the job to a device then it's some other kind of testing.

And with users play with software means they are not doing their true job so UAT is very expensive: pricey since it's manual and pricey because something else isn't being performed. Given this price it is reasonable to reevaluate UAT when possible.

In my experience most UAT stages (although not beta periods ) are in effect an extra form of System Test and are frequently performed by Professional Testers. The fact that these skilled testers do UAT is that the give away. Professional Testers are not Users, they're Professional Testers.

(Another give away is that Professional Testers doing UAT are often compensated for by some group besides the IT department, i.e.. IT test isn't reliable, perhaps for good reason.)

More than once I have observed System Test / Acceptance Test cycles that are either completely absent or very badly done. This necessities the need for a second round. Which is named UAT (possibly to conceal the true problem?)

I also see scenarios were Unit Evaluation is badly done or totally omitted.

If the reduced levels of this triangle have been done well - and - standard built in - then UAT ought to be reduced to some ) real consumers ( b) as near as you can a formality.

UAT is a very costly way to find bugs, in addition, it demonstrates that some thing was missing in the evolution process. Either in programming or before that in understanding the users. It also, perhaps more worryinglythat shows a failing from the prior test measures.
