Developers need to make changes at various scales to keep an existing program in line with rapidly evolving business needs. But without proper control from testers, even minor corrections can cause the entire service to function poorly. Such program failures are tracked through the use of regression testing.
Some experts underestimate the importance of executing such tests. They equate them with repeated tests, giving an idea only about a piece of code and no opportunity to evaluate the program’s work as a whole. In this article, we will try to exhaustively answer the question, what is the essence of automatic regression testing. Also, list ten of its tools that, according to Zapple Tech, are the most common in 2022.

What is Automated Regression Testing
Regression test execution is a comprehensive evaluation of the entire system after any amendment to the code, which includes functional and non-functional tests. Such testing is a highly resource-intensive procedure. It significantly slows down the process of creating software, making it more costly. It is impossible to do without regression tests; there is a known case when low-quality programs caused losses of about 3 trillion dollars. And that’s just in the US.
It means that the problems of time and cost must be somehow solved. Many testers have found that the only way out is to automate regression testing. The advantage is that the procedure will take place with almost no human involvement, provide accurate results, and high speed of testing.
Even though regression testing automation requires the presence of highly qualified testers in the company, its implementation pays for itself 100%.
When are Automated Regression Testing Tools Needed?
Some QA teams still perform manual regression tests. This approach does not justify itself by any parameter – it requires too many human, time, and financial resources. If you’re wondering if it is worth automating, ask yourself these 2 questions:
Why is regression testing a great candidate for automation?
Why is automated regression testing right for you?
The answer to the first question is obvious; in the case of regression testing, its regularity speaks in favor of automation.
As for the second, let us consider which companies are interested in automating regression tests in the first place.
Companies with regularly updated software. Manual testing in such companies would take up most of the time of QA teams. As a result, the software life cycle could not fit into the financial and time frame.
Organizations that emphasize correct test results. Firstly, automated regression testing does not require the intervention of a QA engineer, so it can be conducted non-stop at any time of the day and show a more reliable result. Secondly, the human factor is eliminated in the automated process.
Companies whose projects are limited in time and have a clearly defined budget. The coverage of automated tests significantly exceeds that of manual testing. Thus, more tests can be performed in a given period, the product’s quality can be improved, and it can be brought to the market on time and without additional costs.
Do you recognize yourself in at least one of these points? Then it’s time to think about using regression test automation tools. Zapple Tech will help you decide which ones are worthy of your attention.
Most Popular Codeless Testing Tools in 2023
We have already mentioned that the transition to automatic regression testing, or any other testing, requires the presence of QA engineers with excellent automation skills on the company’s staff. The use of codeless regression testing tools can simplify this process. Consider the most popular of them.
The Subject7 solution is implemented in the cloud and is a platform for any type of testing: desktop, mobile, and web apps.
