How do I build automation test framework for regression testing?

 There will be certain projects wherein developing a software product or application is considered to be complicated. Hence, in such scenarios, regression testing can play a significant role as it helps in re-executing test cases to make sure that the changes made in the software do not impact existing functionality or introduce new bugs. A regression test automation framework helps streamline the regression testing process and makes it more effective. In this article, you will get to know how to build a test automation framework for regression testing.

What is regression testing?

It is a testing method wherein the existing functionalities of the software product or application do not get altered when new changes have been introduced in the code.

What is automated regression testing?

Regression test cases are automated, so that they can be performed several times and problems with any new build can be identified accordingly. These steps are repeated to make sure that every aspect of the product has been thoroughly assessed and that the overall functionality is working as expected.

Incorporating a test automation framework in regression testing:

When regression test cases need to be automated, the test automation framework should be defined by the team through developing a specific plan of action. A proper structure is defined by a test automation framework that will be provided to the test cases when they are going to be automated.

Following are the steps required to build an automation test framework for regression testing:

1. The test automation strategy needs to be properly defined: Before the process of developing a test automation framework is initiated, the test automation strategy needs to be prepared. This involves establishing metrics, technologies and tools that will be used and the scope of automation efforts will also be worked upon.

2. The right test automation tools need to be selected: In this step, the team should decide upon selecting the right automation tools to build a test automation framework. There are several commercial and open-source test automation tools that can be used for leveraging regression testing activities.

3. The test automation framework needs to be built: Once the test automation strategy has been defined and the right test automation tools have been selected, the process of developing a test automation framework is initiated. A framework needs to be created that can be easily updated and maintained as the application evolves.

4. The test automation framework needs to be properly integrated: The integration of an automation test framework should be done with the Continuous integration / Continuous delivery (CI/CD) pipeline. This in turn makes sure that there is an automatic execution of tests as part of the development process wherein immediate feedback of the software quality is provided.

The following are the techniques of automated regression testing:

1. Retest All: All the existing test cases are executed by the QA tester without missing any of the test cases. As a considerable amount of time and resources are consumed, this technique is considered to be a bit expensive.

2. Regression test selection: Execution is done by selecting a subset of the test suite, instead of all the existing test cases being selected. The test cases are categorized into obsolete test cases and reusable test cases. Obsolete test cases will not be used in succeeding regression, whereas reusable test cases will be used in succeeding regression cycles.

3. Test case prioritization: The prioritization of test cases is done based on the frequency of use. A specific level of expertise is required to prioritize test cases. If high-priority test cases are executed first then a maximum number of defects can be uncovered.
