In the software development lifecycle, testing is often underestimated or not given the needed amount of importance as compared to other development stages like UI/UX design. But one cannot deny the fact that testing plays a vital role in helping you overcome complex technical challenges and meet user expectations.
To put it simply, understanding its significance can deliver quality-driven applications, whereas avoiding it may expose them to potential bugs, glitches, and unwanted situations. Therefore, it is imperative to explore various testing types before releasing your product into the market.
Today, we are going to have a detailed discussion on regression testing and discuss the following concepts:
What is Software Regression Testing? Why is Regression Testing Important? What are the Key Regression Testing Challenges and Solutions to Overcome them? How do You Perform a Regression Test? What are the Best Practices to Achieve Seamless Regression Testing? How to Choose the Right Regression Testing Tools?
What is Software Regression Testing?
It is nothing but a type of software testing that helps your testing and quality assurance (QA) teams to execute updates, code changes, or other optimization tasks without negatively impacting your existing application’s performance. In a nutshell, the ultimate goal of this technique is to identify any regressions in an already tested environment.
For instance, let’s consider an app that enables users to add, save and remove data. Now developers want to integrate a unique feature that allows them to edit and update data. Here, testing and QA teams need to ensure that the current features and functionalities of the app work as intended while adding new ones. They also need to verify that no bugs are introduced during the process.
To give you a better idea, let’s take a look at the below areas and understand when to use a regression test for your project.
Adding a new feature or functionality to the software Updating an existing feature with a new requirement An application demanding configuration changes Improving UI/UX abilities Experiencing performance issues along with bug fixes Source code optimization activities and patch fixes Change in the production environment The codebase is fixed to solve defects
To cater to these specific areas or other unexpected turbulent circumstances, it is imperative to have a brief idea about the seven major types of regression testing techniques mentioned below.
