What is Acceptance testing or User Acceptance Testing (UAT)?




After the machine test has corrected all or most flaws, the machine will be sent to the user or client for Acceptance Testing or User Acceptance Testing (UAT).

·         Acceptance testing is essentially done by the user or customer although other stakeholders may be involved also.

·         The objective of approval testing would be to build confidence in the system.
·         Acceptance testing may occur at more than just one level, such as:
·         A Commercial Off the shelf (COTS) software product could be acceptance tested when it's installed or integrated.
·         Acceptance testing of the usability of the component might be done during part testing.

The types of acceptance testing are:

The User Acceptance test: focuses primarily on the performance thereby validating the fitness-for-use of the system by the company user. The consumer acceptance test is done by the consumers and application managers.

The Operational Acceptance evaluation: also called Production approval test ascertain if the system meets the prerequisites for operation. In the majority of the business the operational acceptance test is done by the system administration before the machine is released. The operational approval test could include analyzing of backup/restore, disaster restoration, maintenance tasks and periodic check of safety vulnerabilities.

Contract Acceptance testing: This is performed against the contract's approval criteria for generating custom developed applications. Acceptance should be officially defined when the contract has been agreed.

Compliance approval testing: it's also called regulation acceptance testing is performed contrary to the regulations which must be adhered to, such as governmental, safety or legal regulations.

User Acceptance Testing Is Critical To Successful Software

Image
For companies that deal with generating applications, one of the most critical stages is user acceptance testing (UAT). This is the stage where the bugs have been identified and worked out before it's really released to the public. It's actually existed for the last twenty years or so, but has been known by many distinct titles and was frequently conducted in-house. Today Internet companies specialize in this kind of test for new software in order to ensure that they work before they're released. Although not as thorough as integration and systems testing, this evaluation continues to be rigorous by business standards. To start, company stakeholders need to establish the criteria by which the software is going to be contrasted. As a result, they work collaboratively in the design and preparation of UAT processes, as well as when establishing the standards by which it will be measured. Throughout the procedure, these individuals come to advocate for its usa...

UAT Test Plan

Image
In our series on Testing concepts and fundamentals, this blog post is going to tackle a significant testing practice known as User Acceptance Testing and the UAT evaluation plan. User Acceptance Testing or UAT Testing is an intrinsic part of all Software Testing -- irrespective of methodology. Whether you are using Agile development methodologies or sticking it out with Waterfall, any software product that you construct needs to undergo User Acceptance.  Therefore, UAT is ran following all development and functional testing (read Procedure Testing) is finished, and just before the product is pushed forward to the release or implementation phase. I am sure that you know all this. What is User Acceptance Testing? On the uninitiated, UAT represents essentially the last frontier for Testing to capture any unseemly bugs prior to a product launch to customers. The idea is you won't have the chance to fix any glaring flaws with your product beyond this phase in th...

User Acceptance Testing: Things to Test

  User Acceptance Test (UAT) programs have traditionally been areas of contention between IT and the Business. IT teams get critical systems readied through development and testing, while Business teams verify that these systems meet their requirements.  UAT is one of the final product development procedures that occur before newly developed software is rolled out to the market. What's User Acceptance Testing? User Acceptance Testing is most frequently the final step before rolling out the application. Usually the ending users that will use the software test the application form before'accepting' this application form. Such a testing provides the clients the confidence which the application being delivered to them matches their own requirements. This testing also helps pinpoint bugs related to usability of the application form. Before an individual Acceptance testing could be done the application is fully developed. Different levels of testing (Unit, Integrati...
