Regression testing in agile and DevOps techniques is essential because continuous testing is the cornerstone to these methodologies’ success in maintaining product stability. In this article, let’s figure out more about the significance of regression testing in Agile.

What is Regression Testing?

Testing is performed to check whether any changes in the software code or the configuration settings have caused any significant changes in the features and functionalities of the product.

Regression testing can also be used to ensure no change in how an application works on different platforms, browsers, and configurations.

Regression tests are done in three different phases:

– Preparation phase: Identify the components that might have changed.

– Testing phase: Find out if the changes have broken anything.

– Analysis phase: Decide what went wrong, why it happened, and how to fix it.

Regression testing is a type of software testing that is used to verify that new changes or updates have not broken the core functionality of the product using certain codeless test automation tools.

Understanding the Significance of Regression Testing in Agile

Agile methodology is based on quick, iterative procedures with short sprint cycles that churn out features for each cycle. The testing cycles, in particular, should be short to maintain a suitable balance between sprint development and the iterative testing cycles that follow.

In general, agile development is speedy and dynamic, with engineers churning out features at a rapid pace. The testing and deployment cycles must work together to release new features after they have been tested.

In a genuine sense, development is focused on a single feature, and testing is required for all new and previously produced features. It is a priority and requirement that regression testing is performed on every new build to ensure that the new addition or upgrade in the code does not jeopardize the functionality of current features.

As a result, regression testing in agile is important, and this approach ensures that functionality is not changed for each build. In an agile setting, this regression testing procedure is crucial for product success since it ensures that all features work in accordance with the specified requirements

Benefits of Regression Testing in Agile

Here are a few benefits that regression testing provides us when carried out in an agile environment: 

– As testing is done in sprints in an agile environment to see if newly developed or existing functionalities are performing as expected, it aids in developing a stable product.

– Automating regression testing in agile processes reduces rework and allows testers to focus on other vital testing tasks.

– Incorporating effective regression testing into agile practices helps to enhance overall product quality while also ensuring a positive user experience.

– Identifies any functional flaws early in the product development life cycle, allowing for faster defect remediation.

Conclusion: Today’s organizations require high-quality software that is guaranteed to provide a positive customer experience, as well as quicker release cycles. As a result, it is critical to assure high-quality products that effectively satisfy customer expectations, which can be accomplished by including software testing early in the product development process. Adopting comprehensive regression testing in agile and DevOps methodologies guarantees that quality products are delivered to the market on time since all features are thoroughly tested from beginning to end.
