What is User Acceptance Testing ( UAT)? 

User Acceptance Testing (UAT) is a process by which a user verifies that the developed solution performs as per the requirements set out by the stakeholders. In this article, we will look into what is user acceptance testing and its objectives.  UAT is a method for verifying that a software application meets the requirements and expectations of all major stakeholders including end-users, business managers, and other developers. The UAT process involves multiple activities, including reviewing documentation, training users, setting up test infrastructure, implementing test cases, running tests, analyzing results, confirming fixes, and retesting correctly.

Purpose of User Acceptance Testing ( UAT)

The purpose of User Acceptance Testing (UAT) is to ensure that all user requirements are met by the product before it is released for use in the live environment.

A user acceptance testing (UAT) is a part of the software development life cycle that ensures that all business or functional requirements specified in the software functionality or design documents are present in the delivered software product. It is customer acceptance testing performed against generally established criteria, before the live release of the application to the production environment.

Who will perform UAT?

User Acceptance Testing is the final round of testing performed on a product or feature before it is considered completed. The team will hand off code to clients or users for testing. These users have to work with the software in the real world to ensure the feature meets their needs. They also will look for defects in the product or web application.

Need of User Acceptance Testing

UAT is an essential process in which the developed software or application is tested by the end-user or customer. The primary purpose of UAT is to ensure that the developed software meets the needs and expectations of the customer.

The need for UAT stems from the fact that the development team may develop the software completely in compliance with all the specifications given by the customer but there are chances that when this developed software will be used by the actual users, it may not function appropriately. This may happen due to the following reasons:

  • The actual users do not understand how to use the developed software properly.
  • The actual users find some difficulty in using the developed software in certain situations.
  • The problems faced by actual users were not anticipated and hence may not have been addressed by the development team.

Prerequisites for User Acceptance test

  • A working software with all features in place
  • End-user interest
  • Well defined acceptance criteria
  • A representative sample of the audience for this application
  • Test script or functionality that has been specified by the business people.
  • An exhaustive list of cases based on your functional requirements or your test scripts;
  • A member of the development team who is good at explaining things
  • Some kind of recording device (pen and paper, software like.

How to do USAT

One of the last stages in software testing is UAT, where developers and users test software together. It is only performed after the Software Testing has progressed well and the application is stable. UAT tests are performed to ensure that the delivered software meets or exceeds customer expectations.

Analysis of Business Requirements

Business requirements are the plans that are created to define how an organization will achieve its goals. These are the main responsibilities for which you are accountable. Requirements can be broken up into functional requirements, non-functional requirements, and business analysis requirements. The analysis of the business analysis requirements is known as user acceptance testing (UAT).

Creation of UAT Plan

While user acceptance testing (UAT) is a phase of the overall software testing effort, it requires a separate plan of action because of its importance to the acceptance (or rejection) of the end solution. According to ITtoolbox.com, the primary goals of the UAT plan are to ensure that applications are developed comply with requirements and function as advertised; ensure that end-users understand requirements; conduct gap analysis; verify usability; and satisfy regulatory, legal, or contractual compliance.

Identify test scenario and test case

Before you start testing, you need to know what exactly each test case is going to involve. This is going to help you better identify the type of scenarios that a user might go through when using your application or website. It would also help in identifying potential flaws in your application or website.

Preparation of Test Data

Preparation of test data is the first step in UAT. This takes a considerable amount of time and needs to be done ideally well ahead of the testing so that the actual scenario is not lost. The data required for manual testing usually includes predefined sample data, input from representative users, and expected results through each step.

Run and record the test

After bugs are fixed, you need to go through the process again, only with the updated software.

Confirm business objectives met

User Acceptance Testing (UAT) is a process that helps to confirm that a product or application meets business objectives, works as intended, and complies with required policies and processes.

Exit criteria for UAT

  • Test case document under change control.
  • Notes for the test analyst.
  • Viewing UAT test cases.
  • A platform for running test scripts.
  • Defect tracking system.
  • Approving test results.
  • Setting exit criteria.

The skillset of UAT Testers

UAT Testers should be aware of the following qualities:

  • UAT Testers should have good analytical skills so that they can understand the business requirement and ensure that it has been implemented correctly.
  • UAT Testers should have good communication skills so that they can communicate with the subject matter expert (SME) and get their queries resolved easily.
  • UAT Testers should have the expertise to execute the test cases and ensure that they are executed in a proper manner.
  • UAT Testers should be able to re-create defects and validate the fixes through retesting.
  • UAT Testers should be able to present defects and other issues in a structured format.
  • UAT Testers should be able to work in a team, as there are chances where multiple testers would work on the same project.
  • UAT Testers should be flexible to work on shifts if the need arises, as there are chances where multiple shifts may be working simultaneously on the same project.

UAT Tools

UAT is the final stage of the software testing cycle. It is a process that involves users to assess if the delivered application meets their business needs and fulfills their requirements. The main objective of UAT is to check whether or not the application is ready for its intended purpose, i.e., it satisfies all the requirements, performs as per expectations, and works correctly.

UAT Tools are used by software testers to simplify the tasks of UAT execution. They can also be used by QA managers to manage test cases, track defects, conduct meetings with clients, generate reports, etc. Below are some UAT Tools which are available in the market now:

  • Sauce Labs – It allows you to run functional/regression tests with Selenium WebDriver on real browsers with real browser versions on actual mobile devices with iOS or Android operating systems over multiple mobile networks that are connected to real mobile devices via USB or Wi-Fi.   And more than 2000+ real mobile devices are available for testing on-demand via Sauce Connect or Sauce OnDemand service.     
  • SoapUI   – A free open source tool for building, executing, and documenting API tests.   It provides an exhaustive list of features to design and maintain function.

Conclusion

User acceptance testing, or UAT, is a part of the software development process that tests whether the software meets the end user’s standards. This testing is usually performed by the client or customer. The objective of UAT is to check that the system works as intended and meets user needs. The purpose of UAT is to make sure that all delivered features are available and can be used by actual users.

There are three main purposes of performing UAT:

  • To ensure that the application’s user interface conforms to business requirements.
  • To confirm that each feature works correctly.
  • To ensure that the application functions as a whole.
