The testing process can also be done by making it available for free trial over the internet. It is done with the motive to get any feedback from the user to make further improvements and adjustments before it can be commercialized.
This is known as UAT or User Acceptance Testing, which is also known as beta testing, end user testing or application testing. Testing is done on real-life scenarios and all possible combinations are tested and the functionality is evaluated in terms of efficiency, output, time saved etc.
The entire procedure of UAT begins with planning the UAT, designing it, selecting the team, documenting, bug fixing and then signing off on complete approval.
