Explain User Acceptance Testing (UAT) Process

In this blog post, we’ll gain a thorough understanding of the concept of user acceptance testing, commonly known as UAT testing, the complete process of UAT testing, the main reasons behind performing user acceptance testing, the different tools used to perform UAT Testing, and the benefits as well as drawbacks of performing UAT Testing for any software product or application. 

What is UAT Testing? 

• Before deploying the software application to the production environment, the end user or client performs a type of software testing known as user acceptance testing or UAT testing. 

• User Acceptance Testing or UAT testing is the fourth and final phase of software testing that is done after performing unit testing, integration testing and system testing. 

• The system’s acceptability level is tested in UAT testing with the requisite number of users in a manner similar to black box testing. 

• The user generally performs this type of software testing to guarantee client satisfaction and in order to determine whether the application is performing in accordance with real-world business scenarios. 

UAT Testing Processes 

The processes that the testers should follow to perform UAT testing of a software application are as follows:

• Analysis of Requirements – The testing team analyses the requirements document in this stage to determine the goal of the programmer that has been produced. The project charter, process flow diagrams, system requirements specifications, business use cases, business requirements documents is important and necessary in preparing the test plans. 

• Creation of Test Plans – The entire testing approach is outlined in the process of test plan creation. With this method, it is possible to confirm whether or not the software complies with the requirements. 

• Designing of Test Cases – The development of test cases based on test plan papers is a part of this process. The majority of the acceptance testing scenario should be covered by test cases. 

• Execution of Test Cases – The execution of test cases using proper input values is referred to as test case execution. The testing team gathers input data from the end user before doing each test case with the user to ensure that the software functions properly in the real-world setting. 

• Confirmation of Objectives – The testing team verifies that the software application is bug-free and ready to be provided to the client once all testing procedures have been successfully completed. 

Reasons Behind UAT Testing 

Even though acceptance testing may seem unnecessary once the product has through unit, integration, and system testing, it is necessary for the reasons listed below:

• If requirements change while a project is being developed, it may not be adequately conveyed to the development team. 

• Developers create functions based on their own interpretation of the requirement document, and they might not be aware of the client’s true needs. 

• Acceptance testing is crucial to detect these tiny defects since there may be some that can only be found when the system is actually employed by the end user. 

UAT Testing Tools 

The following collection of tools, which are some of the many available on the market for user acceptability testing:

• Watir : Automated browser-based test cases are run using this tool during user acceptance testing. The Watir UAT tool supports the use of Ruby programming language. 

• Fitness Tool : By entering input data, this tool will automatically generate test cases. The tool requires input from the user in order to run test cases and provide output. For inter-process communication, Java language is used. Using this tool, creating test cases and storing them as tables is simple. 

Benefits of UAT Testing 

Following are some of the benefits that testers usually gain after performing UAT testing:

• Customers are more satisfied since they can test the application themselves. 

• Early definition of the software’s quality requirements allows the tester to choose the testing points in advance. 

• Stakeholders utilize the data from acceptability testing to better understand the demands of the intended audience. 

• As the customer verifies the requirements according to his demands, the requirement definition is improved. 

Drawbacks of UAT Testing 

Although there are a lot of benefits for testers to perform UAT testing, as we have stated above, but there are also some drawbacks:

• Customers are not willing to articulate requirements in their own terms & independently as required by the testing strategy, which negates the purpose of user acceptance testing or UAT testing. 

• If test cases are prepared by another person, the customer cannot comprehend them, forcing the tester to do the inspections alone. 

• Hence, the concept of user acceptance testing or UAT testing fails to exist if the procedure as mentioned above is carried out in this way. 

Conclusion

As a result, from the above discussion, we can conclude to say, one of the several testing types that have developed during the past 25 years is UAT testing. The customer may know exactly “What to anticipate” from the product thanks to user acceptance testing rather than assuming it will be what it is.
