UAT Testing

What is User Acceptance Testing (UAT)? Complete Tutorial

UAT Testing Meaning

User acceptance testing is a last level of the software testing. In UAT testing, customers are involved in this testing to validate final software product against their software requirement specifications. This acceptance testing can be performed at customer’s location.

Acceptance testing can perform after unit testing, integration testing and system testing executed. Acceptance testing has main two types. Alpha testing and Beta testing

UAT testing performed by the customers of a system to verify that system meets their needs and can use in a real-world environment. It is typically the final stage of testing before a system deployed.

During UAT testing, the end-users of the system will perform a variety of tasks and scenarios using the system to ensure that it meets their needs and that they are able to use it effectively. They will also provide feedback on the system’s functionality and usability, which can use to make any necessary improvements before the system deployed.

UAT testing is an important part of the software development process because it helps to ensure that the system meets the needs of the end-users and that it is ready for use in a real-world environment. Its typically performed after system testing and often performed by a group of representative end-users, rather than the entire user base.

UAT Testing

1.Alpha Testing:

Alpha testing mostly done by the development team members. So they perform the alpha testing on the software products. So, they also known as alpha testers.

2. Beta Testing:

Due to Beta testing mostly done by the testers side or end users. They perform the beta testing and collects the feedback from the users. This will be helpful as enhance the software product’s best user experience.

3. Business Acceptance Testing:

In this testing, tester validate that software product developed as per business requirements or not. In BAT (Business Acceptance Testing) main goal is that business profits so sometimes it is quite difficult due to market conditions and latest technologies.

4. Contract Acceptance Testing:

In contract acceptance testing, contract termed as Service Level Agreement (SLA) used when software product goes live for specific time. It should be performed all user acceptance test cases begore go live. In the SLA some of the terms included such as payment will not be made if software product does not meet the all requirements.

5. Regulations Acceptance Testing:

RAT Testing: In this testing, RAT decides the rules and regulations of  the product violates that defined by the government. It will be depends on the government of the country. As it might be negative impact on the software product, first software product has go to RAT(Regulations Acceptance Testing) . If any rules or regulations has found as violated for any region or any country then product will not be eligible for release for specific region.

6. Operational Acceptance Testing:

This testing ensures about testing which are recovery, reliability, compatibility and maintainability. The main focus of this testing is that software application should be stable before it released on the production.

Advantages :

UAT testing involves testing the system with end-users to ensure it meets their needs. This helps the system work effectively in the real world.

Identifies any issues with the system’s usability:

UAT testing allows the end-users to provide feedback on the system’s usability, which can help to identify any issues or problems that may not have identified during other types of testing.

Increases end-user satisfaction:

By involving the end-users in the testing process, UAT testing can increase their satisfaction with the system and their confidence in its functionality.

Reduces the risk of issues being discovered after deployment:

UAT testing can help to identify and fix any issues before the system deploys, which can reduce the risk of problems discovered after the system is in use. This can save time and resources that would be needed to fix issues after deployment.

Helps to ensure the quality of the system:

UAT testing helps to ensure that the system is of high quality and is ready for use in a real-world environment. This can increase customer satisfaction and confidence in the system.



UAT testing can be time-consuming, as it involves testing the system with end-users and gathering their feedback. This can prolong the development process and increase costs.

Requires the involvement of end-users:

UAT testing requires the involvement of the end-users, which can be challenging to coordinate and may require additional resources.

May not identify all issues:

Although UAT testing can help to identify many issues with the system, it may not be able to identify all issues. Some issues may only discovered after the system deployed and in use.

May require specialized testing tools:

Depending on the complexity of the system, specialized testing tools or equipment may required for UAT testing. This can add to the cost of the testing process.

May be disrupted by external factors:

UAT testing typically performed in a real-world environment, which means that external factors such as network issues or hardware failures can disrupt the testing process. This can make it more challenging to obtain accurate and reliable test results.

UAT Testing Example

Let’s say a company is developing a new e-commerce website, and the development team has completed the system testing phase. Before the website launched, the company wants to ensure that it meets the needs of their customers. They will invite a group of customers to test the website and provide feedback on their experience.

During the UAT testing phase, the customers will be asked to perform a series of tasks, such as:

1.Searching for a specific product

2.Adding products to their cart

3.Checking out and making a payment

4.Providing feedback on their experience using the website

The customers will be encouraged to provide feedback on any issues they encounter, such as:

1.Difficulty finding a specific product

2.Problems adding products to their cart

3.Issues with the payment process

4.User interface problems or confusion

The development team will use this feedback to make any necessary changes or improvements to the website before it launched. The goal of UAT testing is to ensure that the website meets the needs of the end-users and provides a positive user experience.


So In this way, UAT (User Acceptance Testing) used in the software testing for improve the quality of the software application and make it defect free product. If you are looking for more testing tutorials then please visit below links:
