Regression testing is one of the testing types in the development of software. Whenever new changes or updates occur in a code, it means going back to the existing code and verifying whether it has affected the outcomes. The applications like ERP and Salesforce CRM are periodically upgraded because most businesses make use of these applications. As there are orderly updates taking place in these applications, regression test automation becomes a necessity.

**Regression Testing – Overview**

Regression testing is one of the types of software testing performed to check whether the software is working as intended. In regression testing, the partial or complete selection of already executed test cases is re-executed in order to evaluate whether the existing functionalities serve their intended purpose as per the predefined rules or standards.

Whenever any change or update takes place in the code, there may be the chance that functionality changes the intended output, so regression testing ensures the overall stability and functionality of existing features.

**Importance of Regression Testing**

Though regression testing can be done manually, it can be quite challenging and monotonous in some cases. For instance, there are some cases like the execution of repetitive tasks, so in that case, performing the regression test automation will smoothen the process of executing repetitive tasks.

Automation testing can be run continuously as there is no need for human intervention while running the test. Schedule the testing with regression test automation and return to it when testing is completed. There will be no need for dedicated time by humans while running the test.

The scope of manual testing is less than automation testing because when the number of the same test cases rises, it leads to less efficiency. Automation testing helps build the products so that their testing can be performed quickly.

Humans are prone to error, and the chances of error increase when a repetitive task needs to be executed. You can do the regression testing on multiple combinations of devices in no time with automation and can also provide a detailed analysis report.

**When to Perform Automated Regression Testing**?

Though regression Testing can be carried out at any stage of development, however, there are some standard times when regression test automation needs to be done. Below are some significant scenarios where automated regression testing better serves the purpose.

**New Application or Feature Is Added**

When a new functionality or feature is added to an application, it can bring changes to the current application and hence leads to changes in output. The possibility may be that the addition of a new feature may alter or impact the personalization and customization.

**Modification is Done in the Current Application**

If the changes like minor workflow accustoming or the addition of a new field are done, then regression test automation can be the best choice.

**Integration With Another Application**

When the application or software is integrated with a third party, then code changes take place, and it may disrupt the existing functionalities.

**Software Update**

Software like ERP requires continuous regression validation because it releases newer updates frequently. Regular updates may alter the functionality.

**Performance Issues**

It is not necessary that regression testing tools can only be used when there is a modification or any update that takes place. Sometimes performance issues also occur that create problems in the standard workflow.

**List of Popular Regression Testing Tools**

●      **Subject** 7: It is a cloud-based, “real codeless” automation testing solution that integrates all the platforms of testing in a single platform. It also permits technical and non-technical users to run the test flows in a robust manner.

●      **Testimony**: It is one of theregression testing tools that is built specifically for SAP software. It reduces the need for the management of test data and ends the test script creation, reaffirming the SAP regression testing.

●      **Appsurify**: It is mainly used when the QA engineers and developers need to fasten up the cycle times, discover errors earlier, and test frequently. This tool minimizes the regression test completion time and maximizes the coverage of the test.

●      **Selenium**: It is considered to be the apex tool that supports regression test automation. Selenium encompasses the cross-environment, OS, and support of browsers. Moreover, it is congruent with many programming and scripting languages and other testing frameworks.

●      **testRigor**: It is specifically used for test maintenance, and it is well-suited when there is a need to create robust automation coverage.

●      **Watir**: It makes use of the Ruby programming language and is a lightweight and easy-to-use tool. It is meant to test web apps.
