The Benefits of Acceptance Testing
According to the overall software development process model (see Figure below)
acceptance testing is a process of comparing the development product to its requirements specification document and the current needs of its end users.

This is a rather unusual type of testing in the sense that it is performed by the consumer or end user of the program and is not the responsibility of the development company. In the case of a contracted software product, the contracting organization (the user) performs the acceptance testing by comparing the program’s functioning to that specified in the original contract.
As in the case with other testing types this test is best performed using test cases that strive to show that the program does not meet the requirements of the contract. If those tests fail, the development product is accepted. The sensible customer always performs an acceptance testing to make sure that the software product it purchases (for example, the operating system or compiler developed by the computer manufacturer, the database management system developed by the software company) satisfies its needs.
Acceptance testing (UAT) that aims to measure the external quality of the product is, as a rule, a multi-stage process conducted based on acceptance criteria. These criteria are the classification threshold for acceptance requirements to the program with which its quality will be judged at various phases of the project.
The requirements specification’s normative content is defined in various normative and technical specification documents. It is a critical step in developing software product with real business value. It helps to improve software quality and overall acceptance rate of newly implemented solution. This process is particularly time-consuming and complicated as it involves testing the software for ‘real world’ application. For example, UAT usually includes all types of testing that are related to system testing and installation testing, as well as a number of additional tests. UAT can be very costly for the project.
The last testing phase shown in the figure above is installation testing. This process is not associated with any phases of the design process, like all other testing processes. It is an unusual type of verification because its purpose is to find installation errors, not software errors.
During the installation of software systems, the user must select many options, place and upload files and libraries, ensure the correct hardware configuration; while this program should be associated with other programs.
