How Regression Testing Enhances User Experience
The significance of a smooth user experience cannot be underestimated, as it often determines whether users will continue using an application or abandon it. For instance, in the case of mobile apps, reports suggest that 90% of users will leave if the user experience and performance do not meet their expectations. Although employees required to use software implemented at their workplaces are unlikely to abandon it, in such cases, entire organizations may be at risk of disruptions due to hindered staff productivity. Implementing regular regression testing can be a fundamental step to improved user experience. Read this article to learn how regression testing can help.

Delivering bug-free software

The primary focus of regression testing is to catch regression defects or bugs that occur after code modifications, which can result from application upgrades, improvements, or fixing technical issues. Conducting regular regression testing from the early stages of development helps detect and resolve bugs early, preventing them from reaching end-users. The absence of bugs that disrupt interactions with an application is crucial for a smooth user experience.

Maintaining stable functionality

One unfortunate scenario in the world of software development is when users abandon an app they once loved because a recent update broke the software’s functionality. Regression testing helps development teams ensure that the desired functionality is preserved across different software versions, minimizing the chances of unexpected breakdowns in the user workflow.

Increased usability

With the rise of automated testing, many teams tend to focus on regression testing types such as functional regression testing, performance regression testing, or compatibility regression testing, which do not require excessive manual work. However, it is essential to remember many other types of regression testing tailored to enhancing user experience, including UI regression tests, usability regression tests, and accessibility regression testing. Although they may rely more on human supervision, they facilitate an understanding of user experience and its weaknesses.

Performance optimization

Performance is another crucial component of user experience, and it is necessary to ensure that any software updates do not affect application responsiveness and reliability.

Regression performance testing, particularly automated, is a powerful way to assess software behavior under load conditions, its response to stress levels exceeding normal operation, and its ability to scale after the introduction of code changes.

Elevated security

Code modifications can also result in security vulnerabilities, which can threaten a smooth user experience as they can lead to unauthorized access, data breaches, and fund theft. Just like in the case of regular bugs, regression testing is also capable of identifying potential vulnerabilities, allowing the development team to address them before user accounts are compromised.

Regression testing for improved user experience – best practices

To fully harness the potential of regression testing for enhancing user experience, it is highly recommended to adopt some of the following best practices into your testing routine.

1. Leverage automation

Regression testing can be a resource-intensive process, especially with the increasing complexity of software and the frequency of updates. Manual regression testing is often impractical for most applications. Even basic automation allows teams to execute test scripts without human intervention, significantly expanding test coverage.

Advanced tools, such as Executive Automats, also automate other tasks like test report generation, offering a user-friendly no-code interface that facilitates faster script creation.

2. Perform necessary manual tests

Not all aspects of user experience can be adequately tested without human involvement. Manual regression tests such as UI tests and usability tests mentioned earlier should not be overlooked. While conducted by human testers, these tests effectively simulate real-world interactions with software and play a critical role in enhancing user experience.

3. Prioritize test cases

Even with automated regression testing in place, it is crucial to prioritize certain tests due to the impossibility of achieving complete test coverage. Adopting a risk-based regression testing approach can be sensible as it directs regression testing efforts towards application areas with the highest potential risks or the greatest impact on critical user workflows.

4. Conduct regression performance and security testing

Regression performance testing can be complex to perform manually, and many automated regression testing tools lack this functionality. Nevertheless, it is highly recommended to ensure that performance testing is conducted alongside other regression tests. This helps developers assess whether applications meet user expectations in terms of software responsiveness.

Regression testing focused on software security is essential for ensuring a robust user experience. Security vulnerabilities can greatly impact user trust and satisfaction, while regression testing for security aspects helps identify and mitigate potential risks before they compromise the integrity and safety of the application.

5. Use representative data sets for testing

The value of regression testing can be compromised if it lacks realism and accuracy. To obtain accurate testing results, it is essential to ensure that regression testing reflects real-world scenarios of user interaction with the tested software.

Bottom line

Regression testing plays a vital role in ensuring that software updates or modifications do not compromise user experience. To fully leverage the benefits of regression testing for improved user experience, it is essential to adopt best practices such as leveraging automation, performing necessary manual tests, prioritizing test cases, conducting regression performance testing, and using representative data sets for testing.
