Regression testing is a critical component of software development that helps to maintain the quality and stability of an application. It enables developers to validate that the system is working as expected after changes are made, which helps to reduce the risk of unintended consequences and improve the overall user experience. This process is essential for ensuring that the software meets the requirements of its users and continues to function optimally over time.
The objective of regression testing is to ensure that any changes to the codebase do not negatively impact the performance or functionality of the application. This type of testing is often performed by automated testing tools, which make it possible to perform tests on a large scale, quickly and efficiently. Automated regression testing helps to minimize the effort required to perform the tests manually, reduce the risk of human error, and improve test accuracy.
Regression testing is typically performed in a series of stages, starting with initial testing and then followed by additional testing after each new code modification. This process is repeated until the development team is satisfied that the software is functioning correctly. Regression testing should be part of the software development cycle, and it is recommended that it is performed regularly to ensure that any changes or improvements to the codebase do not compromise the quality or stability of the application.

In the digital age, applications are the primary mode of consumption for nearly all products and services and brand differentiation lies in providing seamless, omnichannel customer service experience. Organizations have already adopted lean and DevOps ways of development and they have to afford new approaches to test new ecosystem of complex, highly interconnected, APIs and cloud-driven applications. IT leaders cannot pick the two out of Speed, Quality and Cost. They need all three–Speed, Quality and Cost for creating all-inclusive digital journeys.
Regression Testing 101: Selective retesting to detect faults introduced during modification of a system or software component, to verify that modifications have not caused unintended adverse effects, or to verify that a modified system or software component still meets its specified requirements.
“...a testing process which is applied after a program is modified.”
