Automated regression testing - what does it mean?

In the modern development world, the fast pace of work and the need for frequent launches require us to be precise, fast, and most importantly, confident in the quality of our software. One of the most important methods for maintaining a high level of quality over time is performing automated regression tests. In this article, we will delve into the meaning of the term, how these tests are performed, and the clear advantages they offer over manual tests.

What are automated regression tests?

Regression testing is designed to ensure that changes to the code, such as bug fixes, upgrades, or new developments, have not broken the functionality of existing parts of the software. In other words, it checks whether “something broke” after we made a change. When we talk about automated regression testing, we mean that this process is carried out mechanically – by code, not by a human tester.

We at VeriSoft Ltd. specialize in developing automated testing systems that perform these tests consistently, quickly, and without human error. Every change to the code – no matter how small – goes through our testing system to ensure that everything works properly, even after the changes.

Why is it important to perform regression testing?

Software development is a dynamic process. With each upgraded version, we add features, fix bugs, and sometimes make changes to the code structure. Without regression testing, we have no way to know whether a small action we took caused an unexpected violation elsewhere in the system.

This means that without regression testing, the risk of bugs in new versions increases significantly. Such bugs can lead to a loss of user experience, a decrease in customer trust, and even financial losses. The tests solve this problem effectively – they are performed quickly and frequently, and alert you to bugs immediately.

Benefits of automation in regression testing

The move to automation in regression testing gives us enormous advantages:

• Saving time and resources - Instead of testing each version manually, we run all tests with the click of a button.

• High accuracy and reliability - Automated systems are not affected by fatigue, lack of concentration, or human misinterpretation.

• Broad coverage of scenarios - Many scenarios can be tested simultaneously, even those that were difficult to test manually.

• Frequent testing as part of DevOps - Integrating testing as part of the CI/CD process allows problems to be identified in the early stages of development.

We at VeriSoft Ltd. build customized automation infrastructure for each client, including all relevant regression scenarios, and enable ongoing monitoring of system performance after each code change.

How are automated regression tests implemented in practice?

In the first step, we identify the critical parts of the system – those that should not be affected by any update. Then, we write automated scripts for them that simulate user actions and ensure that the final result is correct. For example, if it is a shopping site, we would want to make sure that the processes of adding to cart, paying, and selecting shipping work properly even after new products are added or the management system is changed.

Automated regression tests are written using advanced tools such as Selenium, Appium, and Cypress, and integrated with CI/CD platforms such as Jenkins and GitHub Actions. Any change to the code automatically triggers the tests, and the system alerts if a fault occurs.

In conclusion

Automated regression testing is a cornerstone of any organization's testing strategy aimed at developing high-quality products and releasing versions quickly and confidently. It allows us to identify bugs before they affect users, save time and resources, and ensure that every code change is thoroughly vetted.
