![]() ![]() Unit testing is often done by developers while they code or immediately after to catch defects, and is typically part of the build process when compiling code. As the name suggests, unit testing involves validating small, separate batches of code. It validates test cases that previously passed and can be automated or manual. Conversely, regression testing is sometimes lower-priority. Retesting is a high-priority task that is part of standard development practices. Retesting ensures that the bug fixes put in place actually worked. QA teams use retesting on test cases that previously failed. Both regression testing and retesting involve re-executing test cases, but they are done with different purposes in mind. Now that we know what regression testing is, let’s explain what regression testing isn’t. To do this, they re-run the existing regression test cases or automated scripts again to make sure they pass or catch defects. DIGITAL REGRESS SOFTWARETesters typically execute these tests at the end of the software iteration, prior to release. ![]() Code changes can include new functionality, fixes to defects or performance issues, and requirements changes. Regression testing often occurs on a new build any time there is a change to either the code or the environment where it will run. Regression testing in software testing reduces the risk of poorly functioning features and helps the new version advance toward a production environment. Software systems are often large and have many components connected via APIs, so it’s easy for a simple change to have an unintended negative effect. Regression testing helps ensure the software unifies, meaning it works together as a whole, rather than just as separate components. While most testing techniques aim to identify bugs in new features, this approach looks to simply confirm that the software is running smoothly and is not experiencing any adverse effects from the update. Through regression testing, QA professionals make sure those previously tested components still function as intended, and weren’t inadvertently broken by the new code. QA teams re-run previously executed test cases, such as unit and integration tests, to make sure they still pass after a code change has been made. Software regression testing is a type of functional, black box testing in which the QA team assesses previously tested application features after system changes or modifications are made by developers. DIGITAL REGRESS HOW TOIn this guide, we’ll explain a number of key points, including what regression testing is, how to do it and some best practices. That’s what regression testing in software testing aims to fix, but it takes a tactful approach to avoid delays in product releases. While incremental delivery has many benefits, application changes can always introduce unintended effects on the software, including features that stop working. New features can address defects in functionality or feature requests from users. The Agile software development method pushed organizations to more incremental delivery of software and applications.
