Errors in requirements specifications have been identified as a major contributor to costly software project failures. It would be highly beneficial if information systems developers could verify requirements by predicting workplace acceptance of a new system based on user evaluations of its specifications measured during the earliest stages of the development project, ideally before building a working prototype.

Acceptance testing

It is performed at client location at developer's site. It is a final test before shipping a product to the customers. Mutant Veggies. Test a system or an application with a real-world scenario and data. Still confused with the way in which? UAT tests usually have the goal to check if the client needs are met with the developed solution. If the customer and the supplier agree on the product, the software development starts.

UAT is done in the final phase of testing after functional, integration and system testing is done. It does not focus on cosmetic errors, spelling mistakes or system testing. User Acceptance Testing is carried out in a separate testing environment with production-like data setup. It is kind of black box testing where two or more end-users will be involved. Who Performs UAT? Developers code software based on requirements document which is their "own" understanding of the requirements and may not actually be what the client needs from the software.

What is User Acceptance Testing (UAT)? with Examples

In engineering and its various subdisciplines , acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests , physical tests , or performance tests. In systems engineering , it may involve black-box testing performed on a system for example: a piece of software , lots of manufactured mechanical parts, or batches of chemical products prior to its delivery. Formal testing with respect to user needs, requirements, and business processes conducted to determine whether a system satisfies the acceptance criteria [2] and to enable the user, customers or other authorized entity to determine whether to accept the system. Acceptance testing is also known as user acceptance testing UAT , end-user testing, operational acceptance testing OAT , acceptance test-driven development ATDD or field acceptance testing.

The user acceptance test UAT is the final stage of testing in application software development. When testing results meet the acceptance criteria, the software system can be released for operational use. This paper first compares the different testing phases of software development i. Then, we describe several approaches for acceptance test, including the behaviour-based approach, the black-box strategy and a new UAT strategy called operation-based testing.
