- User acceptance testing is a vital step in the software development process that ensures the product is fit for its intended purpose.
- While full automation in UAT is appealing for its efficiency, a combination of automation and human judgement is essential for comprehensive testing.
User acceptance testing is a testing phase where the software is evaluated based on user requirements to ensure it meets the business needs and is acceptable for end-users. Although full automation is not feasible, a balanced approach that combines the power of automation with the perceptiveness of human testers is the key to successful user acceptance testing.
Understanding user acceptance testing
User acceptance testing (UAT) is conducted to confirm that the software’s business functionality is in line with the client’s expectations. It is typically performed by end-users or user representatives and focuses on the “look and feel” of the application, as well as its usability and consistency with the requirements.
UAT is crucial because it helps identify any discrepancies between the developed software and the actual user needs. It ensures that the software is user-friendly and functions as intended in a real-world context.

Advantages of automation in UAT
Automation can bring several benefits to UAT, such as speed, consistency, and the ability to run tests repeatedly without fatigue. Automated tests can cover a wide range of scenarios and can be integrated into continuous integration/continuous deployment (CI/CD) pipelines for ongoing validation.

Challenges of full automation
Complexity of user behaviour: Despite the allure of automation, fully automating UAT faces the formidable challenge of human behaviour’s inherent complexity. Users interact with software in diverse and often unpredictable ways, which can be difficult to anticipate and script within automated tests. The organic nature of decision-making during testing means that some user actions may not align with pre-defined test paths, rendering a purely automated approach insufficient.
Subjective user experience: User experience (UX) is a critical component of UAT that goes beyond functionality. It encompasses the user’s subjective satisfaction, emotional response, and overall engagement with the software. These nuances are challenging for automated tests to capture, as they require a human perspective that understands and interprets the qualitative aspects of interaction.
The need for empathy in testing: Automated tests excel at verifying that features work under specific conditions but may fall short in assessing how users feel about the software. The empathetic understanding of user needs and the ability to perceive the software’s impact on the user’s mood and satisfaction are uniquely human capabilities that are indispensable in the UAT process.
A mixed method of problem solving
Given these challenges, a mixed method often proves most effective. Automation can handle the bulk of regression and functional testing, ensuring that the software meets predefined criteria. Meanwhile, manual testing can address the more subjective and exploratory aspects of UAT, providing insights that automated tests cannot.
While the idea of fully automating UAT is appealing for its efficiency, the reality is that a blend of automation and human judgement is necessary to achieve comprehensive testing. The human element in UAT allows for a deeper understanding of user needs and ensures that the software not only works correctly but also meets the users’ expectations in terms of usability and satisfaction.
