What Is Usability Testing?

It’s a non-functional testing type focused on assessing how easily and intuitively people can navigate and interact with a product. This form of QA is vital in determining the user-friendliness and overall user experience of an application.

At its core, usability testing involves real people performing specific tasks on the software to identify any usability issues and gather qualitative and quantitative data about the user’s experience. It aims to ensure that the software is intuitive, easy to use, and aligns with the clients’ expectations.

The process starts with selecting a group of people that best represent the target audience of the software, typically those not engaged in its development. These participants are then assigned specific tasks to execute within the application.

During their interaction, various aspects such as user behavior, ease of navigation, frequency of errors, and overall user satisfaction are closely monitored and documented. This gathered data is meticulously analyzed to pinpoint prevalent usability issues and areas needing enhancement.

Finally, based on the findings, the software is refined and improved. This process may be repeated multiple times until the usability goals are met.

Why Perform Usability Testing?

As we already mentioned, usability testing is critical for ensuring a positive customer experience. It goes beyond functional testing by focusing on the customer experience and interaction with the software.

It helps in identifying navigational difficulties, confusing features, and potential frustrations that users might encounter. By addressing these issues, developers can create products that are not only functional but also enjoyable and efficient to use, leading to higher customer satisfaction and retention.

What’s also important, addressing usability issues early in the development process can save time and resources in the future. It helps avoid costly redesigns or modifications post-launch and reduces the need for extensive support and training.

Finally, by involving real people, usability testing gathers firsthand insights into customer needs, preferences, and behaviors. In a market where many options are available, usability can be a differentiating factor, attracting and retaining more customers.

What Is UAT?

It’s a vital phase in the SDLC, where the end product is tested in the “real world” by the actual end users or their proxies. It is performed to ensure that the software meets the required specifications and fulfills its intended purpose from the user’s perspective.

UAT is the final verification step before a product is released to the market. 

It starts with defining the criteria for acceptance, including the objectives, scope, and key functionalities that the app must meet to be accepted by the actual users of the app. They perform tasks and operations that the software is expected to handle in its operational setting.

Then, feedback from people is collected, including any discrepancies from the expected outcomes, ease of use, and any issues encountered. The results of UAT are analyzed to identify any areas that need refinement. Based on the feedback, modifications are made to ensure the app meets the acceptance criteria.

Finally, once the product meets all the acceptance criteria and any issues have been resolved, it receives final approval from the stakeholders or end users.

As we already mentioned, UAT is a core stage in the SDLC, so we recommend following certain best practices to conduct it effectively:

  1. Gather Essential Information: Start by collecting all necessary data, which includes understanding the processes to be tested, the required steps for each test, and the criteria for selecting appropriate test data. This foundational step ensures that testing is based on accurate and relevant information.
  2. Identify the Right Audience: Choosing the correct testers is crucial. These individuals should ideally be representatives of the app’s end users – those who understand the business context and can provide meaningful feedback. Their insights can significantly impact the relevance and effectiveness of the UAT process.
  3. Clarify the Project Scope: Determine which aspects of the project require this testing type and focus on gathering data from these areas. This targeted approach saves time and resources and ensures that quality assurance efforts are concentrated where they are most needed.
  4. Assign Specific Testing Roles: Different QA tasks can be delegated to different people based on their expertise and familiarity with the aspects being tested. Each test case should be clearly documented, outlining the procedures to follow, expected outcomes, and any specific conditions that need to be verified by the tester.
  5. Confirm Business Objectives Alignment: Upon completion of testing and resolution of any identified issues, it’s important to have a formal sign-off process. This step confirms that the changes made during UAT align with the business objectives and requirements. It serves as a formal acknowledgment that the product is ready for deployment.

DogQ specialists recommend following these practices, as they lead to more efficient and effective QA outcomes. By carefully planning, involving the right people, focusing on relevant processes, and ensuring alignment with business objectives, UAT can significantly contribute to the development of an app that not only meets technical specifications but also delivers real value to its end users.

Why Perform UAT?

First of all, it is crucial to verify that the product aligns with the business requirements and objectives. While earlier QA phases focus on technical aspects like bugs and performance, UAT offers insights into how well the app functions in the real world. It is the final checkpoint to ensure that what has been developed is what the end-user actually needs and works as intended in their environment.

By catching issues before the product goes live, UAT helps significantly reduce post-launch problems. This not only saves cost and effort in terms of fixes and patches but also helps in maintaining the reputation of the software.

Finally, in many industries, passing UAT is a necessary step to fulfill compliance and regulatory requirements, ensuring the software adheres to industry standards and guidelines.

Why UAT?

Thus, the significance of this testing type lies in its ability to bridge the gap between the development and real-world application: it is not just a QA phase but a crucial validation process that ensures the software delivers value to its customers and performs as expected in its intended environment.

User Acceptance Testing vs. Usability Testing: Key Differences

While both testing types are essential in the SDLC, they differ significantly in various aspects. Understanding these differences is key to effectively applying each testing method:


Usability Testing

UAT Testing


This is a testing type to evaluate how easily and intuitively users can interact with a product, focusing on the user experience and interface.

It is the process where software is tested for acceptability, ensuring it meets the business requirements and is ready for use by the end user.


The primary goal is to improve the app’s ease of use, navigation, and overall customer experience.

The goal is to validate the product against defined business requirements and ensure it performs the tasks it was intended to in the real-world environment.

When to Perform

Typically conducted early and throughout the development process to continually refine the customer experience.

Generally performed at the end of the development cycle, just before the product is ready for release.

Who Performs

Often involves potential users or people representative of the target audience who may not have in-depth knowledge of the software.

Conducted by actual end-users or their representatives who will be using the app in their daily activities.

Results Focus

Feedback is focused on the user’s experience, ease of use, and overall satisfaction with the product interface.

Feedback revolves around the product’s functionality and its ability to perform required tasks in a real-world scenario.


Utilizes tools that track user interaction, eye movement, and emotional response, like heatmaps and user recording software.

Often relies on business-specific tools that are designed to emulate the real-world operational environment of the software.

As we can see, while both usability and user acceptance are centered around the user, they cater to different aspects of the user’s interaction with the application. Usability testing is about the user experience and interface design, focusing on how real people feel about the software, whereas UAT is about functional correctness and suitability for business purposes. Both are crucial for delivering a product that not only works efficiently but is also well-received and utilized effectively by its intended users.

Can They Be Automated?

The question of automation of these testing types presents interesting possibilities and considerations.

While the core of usability testing involves human interaction and subjective feedback, certain elements can be automated. Tools can track customer behavior, such as clicks and navigation paths, and gather analytics. However, the qualitative aspects like customer satisfaction and ease of use require human observation and cannot be fully automated.

What concerns UAT, many aspects here can be automated, especially the repetitive and data-driven parts. Automated test scripts can be used to verify specific functionalities and workflows against business requirements. However, the final validation by the end user, especially for complex or nuanced business processes, often needs a manual approach.

While not all aspects of usability testing and UAT can be fully automated due to their inherent need for human judgment and subjective feedback, tools like DogQ offer a way to automate significant portions of these processes. It allows teams to automate the above-mentioned QA tasks without the need for extensive coding knowledge. With DogQ, teams can quickly set up automated test cases and scenarios, significantly reducing the time and effort involved in manual testing.
