Regression testing is an important practice in software development. It tests to ensure your application remains stable and reliable even as changes and updates are introduced. Each new change introduces a risk of breaking existing functionalities, potentially causing shipping delays or launch postponements. Evaluating your application against a full suite of tests helps find and fix unexpected software bugs or errors.

QA engineers and developers constantly worry that new updates will hinder the functionality of their applications. Regression testing tools prevent this and ensure that applications run smoothly after a code update. Most QA teams use automated regression testing software to save time and money while speeding up the release cycle. However, these benefits only apply when you use a web testing tool that suits your use cases.

In today's dynamic software landscape, teams struggle with where to invest their time: new feature testing or regression testing. Obviously, ensuring the reliability and stability of applications is paramount so that the end-user experience is not impacted. However, teams must also ensure that new features and capabilities that will propel the company's business to the next level are also properly tested and ready to be put in the hands of the end users.

Here at SmartBear, our motto is that quality isn’t just the goal, it’s the whole point. The software development process is intricate and dynamic, with constant changes being made to meet evolving user requirements and address defects. However, with these changes come potential risks. One of the most significant challenges in software development is ensuring that making modifications to an application does not inadvertently break existing functionality.

Adding new features or enhancements to an app is a good thing – unless the changes trigger an unexpected problem. To protect against this risk, QA teams and developers can leverage automated regression testing, which offers a fast and efficient means of confirming that software upgrades or changes don't introduce bugs into applications.

Regression testing is a must-have testing activity. A quite common best practice is to build a regression test suite consisting of many related test cases for a particular feature. This test suite is scheduled to run automatically after a code update to check if that particular feature is affected by the update. The real question is not about how to build a regression test suite, but rather, on what criteria we should categorize our test cases.

Regression testing is a necessary process that grows over time, consuming larger amounts of testing capacity as applications scale in features. Katalon TrueTest™ addresses this hurdle by using artificial intelligence (AI) to allow quality engineering teams to realign their limited resources to spend more time validating and testing new release features while relying on Katalon to create, maintain, and run regression tests on existing application code.

Because retesting and regression testing have many similarities, it’s easy to get them mixed up. Both are software testing methods used to maintain the usability of a website or web app, and both involve testing your software repeatedly. Thankfully, there are some key differences between the two that are easy to remember when learning how to distinguish one from the other. Read on for a simple breakdown of retesting vs regression testing, so you never end up confusing them again.

Quality assurance is a crucial differentiator in today's software marketplace. Gartner reports, "48% of software engineering leaders say customer or user satisfaction are among the top three objectives they are measured on." (Source: 2022 Gartner Software Engineering Leaders Role Survey). In essence, software quality directly influences customer satisfaction. A cornerstone in ensuring such quality is regression testing.
