Non-Functional Testing: A Complete Handbook for Developers
Non-functional tests assess usability, performance, scalability, and security - all of which determine the success of an application.
This article will discuss this question and the impact of user acceptance testing as part of the software testing life cycle.
User acceptance testing (UAT) determines if a system satisfies its users’ needs and fits the business requirements. Thus, UAT is also known as end-user acceptance testing.
UAT is a process that verifies that the functions of an application work as expected. This means that, unlike other software testing methodologies, end-user tests are conducted at the end of the development cycle to verify how the application functions in real-world conditions.
Furthermore, UAT also serves as an opportunity for the client to consider if the delivered system meets their expectations and specification.
User Acceptance Testing (UAT) is crucial because it helps ensure that the app functions correctly in real-world conditions. It also allows for any errors or bugs to be identified and fixed before releasing the app to end-users.
In addition, earlier attention given to negative user feedback during UAT reduces the number of problems experienced by users after the system is deployed. And because of this, UAT helps to save time and cost in fixing errors after launch.
Other than that, another important reason is that UAT tests can also be used as documentation. This means that the test results of a system’s features and functions will be documented, allowing for future reference without requiring manual testing.
End-user testing is designed to ensure the final product fulfills all user requirements. The actual users of the software do this type of testing to ensure maximum accuracy and usability. The users are testing the software with user profiles that simulate real-world usage. The key benefits of end-user testing are:
What is a UAT session, you may ask? A UAT session is a meeting in which the client and engineers participate. At this stage, software testers communicate with users and technical staff to determine if all project requirements have been met.
UAT sessions are attended by end-users, client representatives, and development team members. The UAT team represents the group that will use the application, while others in attendance can help to determine whether or not an application is ready for live deployment.
The end-users, the actual software users, are to conduct tests of the application in real-world conditions. The client representative ensures that the app meets their expectations. Developers may be present in UAT sessions to ensure no issues with back-end functions or server-side processes.
UAT sessions may vary. However, in general, software testers will begin by explaining the testing process and tools used. Then they typically demonstrate the basic functions of the application. After this brief presentation, it is up to the end-users to test the system themselves under real-world conditions.
After users have tested certain features, the UAT team discusses their findings, often informal. This is usually where any bugs or problems are identified. Only if all features have been tested and no issues have been found will testers proceed with the final testing phase known as System Acceptance Testing (SAT).
The length of a UAT session depends on the project. However, it is typically between one and two weeks.
First, UAT provides an opportunity for developers to understand how the application will be used in real-world conditions. This reduces back-end issues that may arise when the system is live.
Also, UAT sessions allow users and clients to determine if a project meets their specifications. Finally, a UAT session provides an opportunity to identify problems or issues with the app before it is available for use.
Likewise, end-users can provide feedback about the application’s usability. Again, this data can be used to improve future projects.
The art of writing good test cases is essential. They are the foundation of every UAT session.
A test objective gives you direction on what to accomplish. To define a test objective, you must determine what you want to test. What are you looking for? What should be tested in the app?
List the factors that may affect the outcome and how they may do so. For instance, “What controls are in Play?” or “What browser does the user have?”
Next, you’ll need to create the test case. Then, with your objectives in mind, list out specific, step-by-step instructions that end-users can follow.
Finally, before the UAT sessions, create a list of items recorded during testing time. This list should consist of screenshots and any other data the client or engineers may need to identify problems in the system.
Here are some guidelines and tips to keep in mind when developing your UAT Test cases:
In addition to these guidelines, some common usability principles should be applied to every application during testing:
The User Acceptance Testing process is an integral part of the overall testing process, but there are many development stages where it can take place. To best prepare for UAT testing, steps should be taken during each stage to make sure everything is working as expected. Here’s a list of common testing stages with pointers on how to handle UAT throughout the process:
Deliverables could vary depending on the nature of the project. However, a basic list of deliverables could include:
When done correctly, UAT provides valuable insight into user behavior and how they use the application. It can help identify usability problems and offer guidance for making the app more intuitive and easy to use.
UAT testing has a lot to offer from launch validation to checking user behavior and making sure all feedback is heard. In addition, through real-world testing in actual working conditions, you can gain valuable insights into how the application performs.
When it comes to UAT, there are certain criteria that participants should meet for this testing round to be considered successful. Here is a list of core acceptance criteria for user acceptance testing:
While both UAT and beta testing involve external users, the two processes are still different. With beta testing, the main goal is to find bugs with the software’s release candidate. Their primary focus is on stress-testing the product and seeing how it holds up against heavy loads before finalizing or releasing it out into the market. UAT allows end-users to test the product and find problems with actual use. On the other hand, businesses want to know if their customers are satisfied with what they offer.
The two testing procedures are different with varying objectives and goals, but they are both useful in their ways. For example, while it’s important to capture user feedback for launch validation or product improvement purposes, thorough User Acceptance Testing can save time and money when it comes to fixing any bugs before the final launch.
UAT is also different from functional testing, which is done with development teams in mind. While UAT focuses on how actual users will use the application, functional tests are conducted internally to identify issues that could impact the product’s functionality. Both parties need to work together to meet their specific goals and plan accordingly.
User acceptance testing is valuable for companies who want to improve their products and services. It provides an in-depth look into end-user behavior and how they use the product, leading to future improvements and help guide development teams. In addition, UAT can help identify usability problems and offer guidance for making the app more intuitive and easy to use.
With a focus on user satisfaction, UAT testing is a great way to incorporate customer feedback into future product iterations. It also helps with UX testing and launch validation, so you know your users are fully satisfied, and the product will be successful when it reaches the market.
