What is Software Regression Testing?

When developing software, code changes happen frequently. Your team will add new code as your project evolves and program changes occur alongside bug fixes. Any seasoned engineer will tell you that all it takes is one bad line of code to throw off your entire project. So how do you prevent simple changes from turning your work into an inoperable mess?

That's where regression testing comes in.

The Basics of Regression Testing

This testing is about ensuring that recent changes don't affect existing features. It tests that old code still works fine despite the additions or changes made. Regression testing is a critical development task that you must perform regularly. Without it, you can cause irreparable damage to existing code, forcing you to go back to square one.

Regression testing is part of the quality assurance (QA) process. However, many development teams perform it whenever changes and additions occur. It's a safety net that can avoid massive reworks and ongoing headaches in the future.

How Does Regression Testing Work?

There are a few different types of regression testing techniques. A solid software alternative to Selenium can help you dictate the parameters of the test in plain English, making it more approachable to manual QA testers, managers, and more.

The first technique is to "Retest All." With this method, you re-execute all tests in the testing suite. It's time-consuming but may be necessary if the code has the potential for widespread influence.

The next technique is "Regression Test Selection." This option is more selective, re-executing tests on only relevant tests in the test suite.

Finally, there is "Prioritization of Test Cases." With this type of regression testing, the selection of cases comes down to business impact, influence on critically used software functions, etc.

Regression Testing Made Easy

Regression testing can be a headache, but the right tools make it much more manageable. A software testing alternative to Selenium takes the guesswork out of this much-needed QA process. Automating the process eliminates manual work, leading to more efficiency and better testing insights.
