Welcome back to our MakeAnApp, where we regularly post technology or programming updates. Today we will learn about What is user acceptance testing and how we can perform perfect user acceptance testing in software engineering.

So it’s when we are talking about this software testing at the end of the development and testing phases UAT plays a very important role for applications going to be live for those looking to understand each and every aspect of the UAT; please read it carefully.

What are the user acceptance tests?

So let’s begin with the user acceptance testing. User acceptance testing is the last phase of this software testing process. During UAT, the actual software user tests software to ensure it can handle all the tasks in real-world scenarios.

User Acceptance Tests (UAT) are essential for the successful launch and maintenance of any online platform. Whether a mobile application or an e-commerce site, user acceptance ensures that your site or mobile application works as intended and determines whether the user accepts them.

User acceptance is carried out when other tests, such as functional tests, solution, performance, and robustness, have already been carried out. It represents the last step in the testing process before a product is put into production.

User acceptance tests demonstrate that the required functions of a test object work in a way adapted to real-world use. Therefore, user acceptance tests concern both software performance and human behavior.

It is essential that the features of the test software and the intuition of the end user are in harmony. In practice, testers observe and document what happens when they try to perform tasks such as placing an item in a shopping cart or logging in to a customer account.

According to specification, the owner already defines that, or we can see the end user who will deploy in production. UAT is one of the final, most critical software project procedures that must occur before newly developed software is rolled out to the market

According to a computer recipe book, the user acceptance test is important because it helps demonstrate that the test software works in a way adapted to the real world. If the expected result is not achieved during testing, the item will be documented and returned to the developers for optimization.

This process serves as a final verification to ensure that the product is well developed for users. But make no mistake, it is not because the user acceptance test is the final test carried out before production that no bugs are discovered! These bugs can ruin the user experience and even make the software unusable.

Because of these issues, the benefits of uat service are significantly greater than costs. User acceptance tests usually take only 5 to 10% of the project time, but they can save nearly 30% of total costs (compared to not performing tests at all). This is a good way to ensure a good return on investment of projects.

Each anomaly, or bug, is synonymous with user dissatisfaction and loss of income for the brand. Users should not be the ones who discover software bugs! There are several ways to conduct these tests: you can launch a campaign in the laboratory or by crowd testing. In any case, many humans must do these tests versus automated ones.

Enterprise Application Testing Methodology?

What are the 5 types of user acceptance testing?

There are the major 5 types of UAT testing in software engineering.

  1. Alpha & Beta Testing.
  2. Contract Acceptance Testing.
  3. Regulation Acceptance Testing.
  4. Operational Acceptance testing.
  5. Black Box Testing

Why don’t developers do the UAT tests?

Of course, developers ensure that the code they have written does not contain bugs. However, functional but also user tests should be carried out by an independent body.

Judge and party?

Outsourcing of these tests ensures that the test results are objective. Quality assurance professionals bring an essential and new perspective to the software.

Failure to perform user acceptance tests creates avoidable work for developers and generates high hidden costs. Most developers are already working with reduced deadlines and are very busy. They don’t have time to test their work effectively.

Focus your resources on their added value

In other words, developers should develop project managers, manage current projects and entrust the test to quality assurance professionals. In addition, if developers test their own work, they increase the risk of biased results.

Post-production patches also take much longer to resolve and can impose an unnecessary burden on developers. In addition, it has been proven that software is often more likely to go into production with bugs when tested by developers.

With exploratory tests, independent testers discover the product for the first time and, therefore, they discover the bugs that developers may miss. In short, a software testing company is much more effective than developers in finding bugs during user acceptance tests.

In which phase of SDLC is the user acceptance testing started?

User acceptance testing starts in the final phase of testing just before the launch and after functional, integration and system testing is done. So after completing the development and the testing phases, UAT introduce at the end of all testings.

What are the examples of user acceptance testing?

User acceptance test example for financial application.
1. Test new user should not able to transaction.
2. Maximum 10k can transfer per day.
3. App should not login on public network.

How many types of UAT are there?

There are 5 types of User Acceptance Testing Exists in the software development life cycle
1. Alpha & Beta Testing
2. Contract Acceptance Testing
3. Regulation Acceptance Testing
4. Operational Acceptance Testing
5. Black Box Testing

Who performs User Acceptance Testing?

1. Product Managers/business analysts/Client
2. End users.

What is the difference between functional testing and UAT?

User Acceptance Tests consist 5 types of test that is alpha test, contract test, regulation test, operation test, black test which verify that whole application is bug-free. On the other hand Functional testing confirms that particular functions is working fine in the whole application. Suppose its Youtube, Signup function is working fine but uploading video feature has bug.

What are the best tools for software UAT Testing?

Top popular tools for UAT testing management.
1. Tricentis qTest Platform
2. Rally Software
3. Zephar Application
4. Atlassian Jira Software
5. TruRT

The key points for UAT Testing Process

The value of acceptance tests is immense for any test project because the tests serve as a final control to ensure that the product is bug-free and whose ergonomics are experienced as imagined. The final control that acceptance tests provide offers a significant return on investment.

Developers should not perform user acceptance tests because they do not have time. The use of developers carries the risk of biased test results.

Independent tests carried out by quality assurance professionals have been proven to be more effective than tests carried out by product developers.
