Although finding the right schedule for regression testing can be complicated at first, by investing in this process, you can ensure your software is free from any risks and incidents. So, how often do you need to run these tests? The answer to this often depends on who you ask. That way, you reduce your risk of a customer coming across a problem with your software before you do.

Others say you can adjust your regression testing schedule based on the kinds of evaluations you want to run. Software development is a complex combination of art and science. Creating your software is just one part of the puzzle. Maintaining the functionality of that software is a significant part of what makes it successful. Before you can figure out how often to run regression tests, you may need a better idea of the kinds of regressions that can take place in your software.

Sep 27, What is Regression Testing? When to apply regression testing Typically, regression testing is applied under these circumstances: A new requirement is added to an existing feature A new feature or functionality is added The codebase is fixed to solve defects The source code is optimized to improve performance Patch fixes are added Changes in configuration Why is regression testing important?

How to perform regression testing Regression testing practices vary among organizations. However, there are a few basic steps: Detect Changes in the Source Code Detect the modification and optimization in the source code; then identify the components or modules that were changed, as well as their impacts on the existing features.

Prioritize Those Changes and Product Requirements Next, prioritize these modifications and product requirements to streamline the testing process with the corresponding test cases and testing tools. Determine Entry Point and Entry Criteria Ensure whether your application meets the preset eligibility before the regression test execution. Determine Exit Point Determine an exit or final point for the required eligibility or minimum conditions set in step three.

Schedule Tests Finally, identify all test components and schedule the appropriate time to execute. Tools for Regression Testing Katalon Studio Katalon Studio is an end-to-end automation solution that supports functional and regression testing, transforming these processes into easy and simple tasks for testers.

Download Katalon Studio Selenium Selenium offers a set of features used to automate web applications. Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software components.

In simple words, We do regression by re-executing the tests against the modified application to evaluate whether the modified code breaks anything which was working earlier. Anytime we do modify an application, we should do regression testing we run regression test. Also Read: What is Retesting? When Do We Do Retesting?

Regression testing gives confidence to the developers that there is no broken functionality after modifying the production code.

It makes sure that there are no unexpected side effects. Hope you have understood what is regression tests. These functions allow users to add data, save data and delete data. Now developers are developing a new feature i.

This feature allows users to edit and update the data. As a tester, you have to verify the introduction of a new feature ie.

Unit Regression Testing is done during the unit testing phase and the code is tested as a single unit without any dependencies. Dependencies if any are temporarily blocked to test the unit independently.

Partial Regression Testing means when regression testing is done on a module where the change in the code is related to that particular module and there wont be any change impact on other modules. Complete Regression Testing means when regression testing is done on a number of modules where the change in the code is related to the other module is uncertain.

Software maintenance is the process of modifying a software application which includes improvements, bug fixing, deletion of existing features, and optimization. When we do these modifications, the system may work incorrectly. To avoid issues while modifying the code, we do follow regression testing techniques.

These techniques help us to eliminate the risks associated with the modifying code. All the test cases in the existing test bucket or test suite are re-executed to verify that there are no bugs that occurred due to the modified code. This is a very expensive method as it needs enormous time as well as resources when compared to the other techniques.
