What is User Acceptance Testing (UAT)? with Examples
What exactly is UAT?
In software development, User Acceptance Testing (UAT) is a type of testing that is carried out by an end-user or a client to verify and accept a software system before deploying the software application in a production environment. UAT is performed at the end of the testing process after all functional, integration, and system testing has been completed.
Purpose of UAT
The primary goal of user acceptance testing (UAT) is to validate end-to-end business flow. It does not pay attention to grammatical errors, spelling mistakes, or computer system testing. User Acceptance Testing (UAT) is performed in a separate testing environment with data that is similar to that used in production. It will be a type of black-box testing in which two or more end-users will be involved in the process.
Who is responsible for UAT?
UAT image testing is carried out by the client’s end users.
The Importance of User Acceptance Testing
As a result of the need for User Acceptance Testing after the software has gone through the Unit, Integration, and System testing phases, because developers may have built software based on requirements documents based on their understanding, and further required changes during development may not have been effectively communicated to them, it is necessary to conduct User Acceptance Testing to determine whether the final product is accepted by the client or end-user.
What is User Acceptance Testing (UAT) and why is it important?
Developers code software in response to a requirements document that represents their “own” understanding of the requirements and which may or may not correspond to what the client requires from the software.
It is possible that requirements changes will not be communicated effectively to the developers during the project.
Acceptance Testing as well as the V-Model
When modeled as a phase of the Software Development Life Cycle, user acceptance testing corresponds to the requirement phase (SDLC).
Acceptance Testing and V-Model
User Acceptance Testing is predicated on the following conditions:
The following are the eligibility requirements for User Acceptance Testing:
Prerequisites of User Acceptance Testing:
The application code should be completed in its entirety.
Unit testing, integration testing, and system testing should all be carried out at this point.
There are no show-stoppers. The presence of high and medium defects during the System Integration Test Phase –
Only cosmetic errors are acceptable before UAT Regression Testing is completed, and no major defects should be discovered.
Ensure that all of the reported defects have been fixed and tested before completing the UAT Traceability matrix for all of the testings.
It is necessary to have a UAT environment ready.
The System Testing Team’s signature on a mail or communication indicates that the system is ready for user acceptance testing (UAT).
How to Perform User Acceptance Testing (UAT) UAT is performed by the people who will be using the system or software. Beta Testing is a type of Software Testing that takes place at the client’s location, and it is referred to as such. As soon as the entry criteria for UAT are met, the following tasks must be carried out by the UAT testers:
How to do UAT Testing
Process Analysis of Business Requirements Using User Acceptance Testing
Developing a plan for user acceptance testing (UAT)
Determine the Test Scenarios
Create User Acceptance Testing (UAT) Cases
Preparation of Test Data for Analysis (Production like Data)
Carry out the Test cases.
Keep a record of the outcomes
Confirm the company’s goals and objectives.
Step 1) Analysis of Business Requirements
The identification and development of test scenarios are one of the most important activities in the UAT. Following are the documents that have been used to develop these test scenarios:
Business Use Cases for the Project Charter
Process Flow Diagrams are a type of diagram that shows how a process works.
System Requirements Specification (SRS) and Business Requirements Document (BRD) (SRS)
Step 2) Creation of UAT Plan:
In the User Acceptance Testing plan, the strategy that will be used to verify and ensure that an application meets its business requirements is laid out. It outlines the entry and exit criteria for user acceptance testing, as well as the approach to testing scenarios and test cases and the timelines for testing.
Step 3) Identify Test Scenarios and Test Cases:
Identify the test scenarios concerning the high-level business process and create test cases that include clear test steps to verify the scenarios. The majority of the UAT scenarios should be adequately covered by the test cases. The Business Use Cases are used as input for the development of the test cases.
Step 4) Preparation of Test Data:
It is recommended that live data be used for user acceptance testing. For reasons of privacy and security, data should be scrambled before being used. Testing should be done by someone familiar with the database flow.
Step 5) Run and record the results:
Test cases should be executed and any bugs should be reported. Once the bugs have been fixed, retest them. Execution can be accomplished through the use of Test Management tools.
Step 6) Confirm Business Objectives met:
After completing the UAT testing, Business Analysts or UAT Testers are required to send a sign-off email. Following approval, the product is ready to be put into production. Test Plan, UAT Scenarios and Test Cases, Test Results, and Defect Log are the deliverables for user acceptance testing.
Exit criteria for UAT:
Before going into production, the following points should be taken into consideration:
Qualities of UAT Testers:
UAT’s business process is up and running satisfactorily. Meeting with all stakeholders to conclude the project
UAT testers should have the following characteristics:
What is User Acceptance Testing (UAT) and why is it important?
A good understanding of the business is required of the UAT Tester. He should be self-sufficient and think as if he were an unknown user of the system. To ensure the success of the UAT, the tester should be an analytical and lateral thinker who can combine all types of data.
Testers, Business Analysts, and Subject Matter Experts who are familiar with business requirements or flow diagrams can prepare tests and data that are realistic for the business environment.
The following factors must be considered for UAT to be a success:
Prepare a user acceptance testing plan early in the project life cycle.
Prepare a Checklist before the User Acceptance Testing (UAT) begins.
Pre-UAT sessions should be conducted during the System Testing phase itself.
Set clear expectations for UAT and define the scope of the project.
Test the business flow from beginning to end and avoid system tests.
Real-world scenarios and data should be used to evaluate the system or application.
Consider the perspective of a new user to the system.
Usability testing should be carried out.
Conduct Before moving on to production UAT Tools, a feedback session and meeting should be held.
There are several tools available on the market that are used for User Acceptance Testing, and the following are some examples:
It is a Java tool that is used as a testing engine for the fitness tool. It is simple to create tests and record the results in a table using this program. Users of the tool enter the formatted input, and tests are generated automatically as a result of their actions. The tests are then carried out, and the results are returned to the user as a result.
It is a toolkit that is used to automate browser-based tests during User Acceptance Testing (UAT), according to the developer. Rust is the programming language that is used for inter-process communication between the ruby and the Internet Explorer applications.
Some Examples of UAT Policies and Procedures
The majority of the time, in regular software development scenarios, user acceptance testing (UAT) is performed in the QA environment. Even if there is no staging or UAT environment, UAT is classified into Beta and Alpha testing. However, when software is developed for a service-based industry, this classification is not as important.
When the customer is involved to a greater extent, user acceptance testing makes more sense.
User Acceptance Testing (UAT) is the full form of User Acceptance Testing (UAT) in software engineering.
In the last twenty-five years, there has been a plethora of different types of testing that have emerged.
Instead of assuming, the client can be certain of “What to expect” from the product thanks to user acceptance testing.
The advantage of using user acceptance testing is that there will be no surprises when the product is launched onto the market.
