The regression testing market is projected to grow at an annual rate of 8% until 2027, highlighting its importance in software testing. This testing method identifies unexpected outcomes in functionality caused by code changes, ensuring existing features remain intact. Various types of regression testing, such as unit, partial, and complete, are available to meet specific project needs.

2. As per research, the market for regression testing is expected to rise at an annual growth rate of 8% till 2027.
The numbers clearly project the prominence of regression testing in the software testing and development
domain. When multiple commits are frequently made by developers, the unexpected outcome in the overall
functionality that has been caused by each summit is clearly identified by the regression testing method. In this
article, you will get to know the strategic importance of conducting regression testing before deployment.
What is regression testing?
It is a testing method that verifies whether the new changes that have been introduced in the code do not
alter or modify the existing functionalities of the application. It ensures that the existing functionalities are
working fine, despite introducing changes in the code or when a new feature has been introduced. Unit
regression testing, partial regression testing, complete regression testing etc., are some of the important types
of regression testing that can be used based on project requirements.
