What is the Significance of Regression Testing in Agile?

It is a widely understood fact that regression testing is a crucial cog in the Software Testing Life Cycle. It is primarily carried to verify if the new code has brought about any changes to the existing functionality of the desired product or application.

Regression testing enables testers to identify bugs or errors in the build when there is a code change. Testers need to ensure that all features and functionalities are working seamlessly even when the code changes are done.

Leading software testing companies have consistently gone about implementing regression testing in Agile. In this post, we will discuss the significance of this process in agile.

Types of Regression Testing

Before getting into how much of an impact regression testing has had in Agile, here is a quick dive into the types of regression testing.

Unit Regression Testing

Unit Testing is an important type of regression testing that must be taken up during the initial unit testing phase and tests the code as a single unit. This form of regression testing comprises a narrow approach and is extensively focused on individual units of code.

Partial Regression Testing

Partial regression testing is performed to check for issues when small changes are made to the existing code. This process ensures the system is working properly after this code is added or when the desired changes are made.

Complete Regression Testing

This is a comprehensive regression testing method where QA teams are needed to test each unit with a changed code along with the original application features.

This process is taken up to test when multiple code changes have been done. It ensures seamless product release or delivery to check if all functionalities are working.

Build-Level Regression Testing

Build-Level regression testing is carried out during the second build of an impending software product delivery and is often implemented when there are code changes carried out across the builds.

Challenges Faced by Agile Team During Regression Testing

When Agile testing teams perform regression tests, they come across the following challenges:

Too Many Changes:

The software development process has instances where the stakeholders and analysts will suggest relevant to the requirements. These changes could turn out to be unstable due to which the agile team will find it hard to implement the automation testing strategy successfully.

Time-Consuming:

Testing of large applications evidently consumes a lot of time. Creating and managing a regression test suite will require more time which will procrastinate the process for the agile team.

Management of Regression Tests:

The scale of regression tests increases substantially with each sprint. If the desired project is large, it becomes very difficult to manage regression tests. To manage regression tests effectively, testing teams need to automate and review tests consistently.

Poor Communication:

Regression testing demands that there must be an effective communication channel among all the parties involved in a project including stakeholders, developers, business analysts, and testers.

Proper communication ensures the regression testing process is streamlined as it should be. Along with this, the teams can determine the specific features that require regression testing.

Maintenance:

Maintenance is one of the biggest challenges as it takes a considerable amount of time to maintain and update the regression test suite. A lot of this time is consumed when new regression test cases are updated or created.

If the desired scenario is agile testing, there are more frequent build cycles and continuous changes are added to the application. This makes maintenance of recurring changes a tedious task

Significance of Regression Testing in Agile

Agile methodology in software testing revolves around a rapid process with sprints that get shorter in each cycle. The testing cycles here also need to be short to maintain a proper balance between the test cycles that follow.

Because agile testing is a rapid process, regression has its own significance in ensuring there are no functionalities that are affected after each build. As these two processes are highly critical to every software testing project, it becomes imminent for qualified professionals to implement them.
