Top Regression Testing Tools

Aug 26, 2020
7 min read

In an agile market, regression testing is critical for maintaining a high quality of software. The success of any software depends on how successful was regression testing. While functional tests are essential for ensuring the proper functionality of the software, regression testing slows us to ensure stability after every sprint at each stage.

Regression testing is necessary to verify that updates or new code don’t affect existing features. The testing team can’t ignore the regression cycle because any bugs they fail to detect bugs will directly reach the end users. So, regression testing is necessary for ensuring the reputation and credibility of a company.

For this reason, our team has compiled a list of the best regression testing tools available in the market. We will analyze the meaning of regression testing and highlight key features, pros, & cons of regression testing tools.

Regression Testing Definition

Regression testing is a type of software testing technique where we use incremental validation for testing a product. Its purpose is to validate new changes in a product and verify that they don’t affect the product’s existing functionality during development. Testers must add new test cases for every new feature so they can cover all features effectively.

Developers benefit from regression testing not just because it identifies issues within the software, but also because it reflects on changes impacting the system behavior. That said, it also creates a challenge for testers as they must create or select test cases that are more realistic, repetitive, and relevant.

Although we use regression testing in all kinds of testing models, it is more successful in Agile Testing. If applied correctly, we can reduce the testing cost significantly in the long run by using regression testing. It plays a key role in building confidence in software as it reduces the risk of unintended side-effects.

With the demand for new features rising every day, the scope of regression testing will also increase. However, as that happens to do regression testing manually will not be viable. This I why it’s best to rely on an automation framework and testing tool that meets your testing requirements effectively.

When Is It Useful to Perform Regression Testing?

Regression testing can be helpful in a number of scenarios; here are some of them worth noting:

  • In software that always needs to add new features.
  • For minimizing manual testing efforts
  • To verify fixes of bugs reported by customers
  • For testing product enhancement
  • When you are expecting changes related to a product’s performance

tips for efficient web application performance testing
Apr 4, 2024

Performance testing is one of the most challenging components of web application testing. But it is worth it: if done right, performance testing can forecast product behavior and its response to user’s actions with an impressive amount of detail and precision. Irrelevant web performance test data or wrong metrics chosen during testing cost companies a lot of money and effort, while not monitoring your web application performance at all can lead directly to a crash, say, on Black Friday, if you are not prepared to handle an increased number of concurrent users. Business or product owners needn’t know exactly how to performance test a website, but it’s useful to have a basic understanding of procedures that you pay for. From this post, you can learn what web application performance testing is, when it should be done, and how.
