If you ask experienced product designers to give you just one single piece of advice on how to design products, most probably you’ll hear ‘Test early, test often.’ Testing is an activity that defines product success. By its nature, all design decisions are hypothesis. Even when designers put a ton of effort into designing a product, what they come up with is still need to be tested.

1. . Contract and regulation acceptance testing In contract acceptance testing, a system is tested against acceptance criteria as documented in a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards.
2. User Acceptance Testing – UAT is a type of testing performed by the Client to certify the system with respect to the requirements that was agreed upon.This testing happens in the final phase of testing before moving the software application to Market or Production environment.

During product development cycle, a product undergoes through various types of testing. But there’s one particular type of testing that is carried out at the end of the testing cycle — user acceptance testing.

Manual Testing is the process of testing software manually for issues that may impact on an end users’ ability to utilise the software for its intended purpose. The bulk of testing is still done manually. It’s not surprising then, that organisations have low levels of test coverage and throughput.

In this article, I’ll explain user acceptance testing in details.

What is user acceptance testing

User acceptance testing (UAT) is a process of verifying that a product works for its target audience - meets both the requirements and expectations of product’s users. UAT is one of the final product development procedures that occur before newly developed software is rolled out to the market.

Who performs UAT?

Unlike many other types of testing, UAT isn’t performed by professional testers. Product’s end-users are people who take part in this activity.

Notice: It’s extremely important to avoid conducting UAT with product team members as test subjects. People who are familiar with a product might become a victim of tunnel vision. Tunnel vision is bad for two reasons:

First, team members may skip some steps of a journey or use workarounds over some known issues. As a result, it becomes harder to identify any flaws in user flows.

Second, testing with team members won’t reflect the real user reaction on the system (e.g., it won’t be possible to tell whether or not users are interested in a product in the first place).

Why UAT is important

Companies who suffered significant losses due to post-release issues know why it’s important to conduct proper user acceptance test. The cost of fixing defects after a product released on the market is much higher than fixing it before.

By verifying that a product works as intended for its users, product team reduces the likelihood of issues being raised when the product will be released on the market.

7 Tips To Conducting Great UAT

Now when you know the benefits and necessity of UAT it’s time to describe the factors that should be taken into account while planning and conducting UAT:

1. Set clear expectations

Set clear expectations around the desired outcome for UAT. Both team members and test participants should understand why you conduct UAT in the first place. When people understand the value of the activity, they are more happy to participate in it.

2. UAT should occur early and often

In traditional waterfall model of creating products, UAT doesn’t occur until later in the cycle closer to the delivery date. Even in the modern Agile world, many companies still follow this practice. The risk with this approach is simple: waiting until the product release to discover that a product team misunderstood some requirements make the costs for fixing much higher. That’s why regardless of product development process, UAT as a planned activity needs to be scheduled across the life of the project.

3. Find relevant test participants

It’s extremely important to find the right test participants. People who will test your product should be the people who will use it on a regular basis.

Here are a few things to remember:

Stays away from professional testers. Professional testers are people who earn money by testing different products. While professional testers can be good for any other types of testing, it’s vital to avoid them during UAT. Why? Because they don’t represent real users.

Practice beta-testing. Making a beta-version of your product available for your existing users and tracking feedback from them might help you gather valuable insights.

4. Prepare test assignments

Since the goal of UAT is to assess if the product can support day-to-day operations, all tasks and assignments for UAT should be created based on the real-world scenarios. Test scenarios should be a good representation of a user journey.

Here are a few tips for designing test assignments:

• Test scenarios should be created with respect to high-level business requirements. You can use user stories as a foundation for acceptance testing scenarios. Each test assignment should cover a specific usage scenario of the product.

• Create test scenarios with clear test steps. Stay away from business-oriented language when writing test assignments. Use the language of your users to describe the tasks.

• Focus on quality not quantity of assignments. Remember the Pareto principle and strive to create the most focused testing assignments. Your test plan might be created around the top three most common tasks, or the top three most difficult tasks.

• Test your test assignments. Make a trial run of testing before conducting actual test session with real users. This trial run will prevent you from creating bumpy test assignments.

• Try to reuse test cases. Design your test cases in a way that allows utilizing them during each future UAT iteration.

• Last but not least, you can start working on test assignments way before you have a final version of your product. It’s possible to use an interactive prototype to verify key assignments. Creating the one using Mockplus is easy.

Mockplus allows you to create an interactive prototype and test it with your users.

5. Don’t focus on finding defects

Remember that UAT is not performed with the aim of finding maximum defects. All defects should be found during the previous phases of testing. If the users find a bug that wasn’t reported by quality assurance department – it is very bad news for the quality assurance department. UAT should be focused on tracking user responses on interaction with a product.

6. Clarify all findings

After completion of UAT, test participants might report some issues, change requests or new functionalities. Since actual users, not professional testers perform UAT, it would be unfair to expect them to report the findings like professional testers. Thus, it’s essential to spend some time clarifying the findings. In some cases, it worth conducting a quick after-testing interview with test participant.

7. Communicate feedback

As a person responsible for a test session, you need to take action for the following user feedbacks. The results of testing sessions in a format of test reports should be forwarded to the product team who will be responsible for analyzing and making appropriate changes. Reports should encapsulates and communicates the degree to which users expectations were met.

Conclusion

UAT helps product team set expectations on what’s about to happen when a product will be released on the market. Adequately conducted UAT will give product team confidence. I hope the tips mentioned in this article will help you overcome various challenges and execute a successful user acceptance testing.

Stands for 'User Acceptance Testing.' UAT is a process designed to help ensure products will meet user expectations when they are released. It involves running a product through a series of specific tests that help indicate whether or not the product will meet the needs of its users. While the user acceptance testing process can be applied to any type of product, in the computer industry, it is most often associated with software programs.

Software applications typically go through multiple development stages before being released to the general public. These stages include the initial development process, the alpha testing stage, the beta testing stage, the release candidate stage, and the public release of the software. Not every software program goes through each one of these stages, but most software programs are tested by multiple users before they are released.

The primary UAT stages of software development include the alpha and beta testing stages. In the alpha testing stage, a limited number of users within (and possibly outside) a company test an early version of software for bugs and user interface issues. In the beta testing stage, a larger group of users (usually outside the company) test the software and provide feedback, including bug reports and usability issues. This feedback lets the software company know if the product is meeting user expectations and enables the development team to make the necessary revisions before the official release.

Because software is relatively easy to modify and update (unlike hardware products), user acceptance testing may continue even after a software program is released. Many programs now include feedback and bug submission forms directly within the software, which allow users to provide feedback as they use the software.
