Regression testing is a type of software testing that verifies whether previous functionality still works, as expected, after making any changes or enhancements to the product. Regression testing ensures that changing a code or functionality in one part does not have any impact on the other parts of the system or the overall system’s performance. It helps to detect any regression faults, identify bugs and assess the overall risk of any code changes made.

Regression Testing: A Crucial Part of Software Development

Software development is a complex process that involves constant changes and updates. With each change, the programmers and developers run the risk of introducing new bugs into the system, or breaking existing functionality. This is where regression testing comes in, as a vital tool to ensure that the software continues to perform as expected.

Regression testing is a type of software testing that involves retesting previous functionality to ensure that there are no new defects introduced in the system. It helps to identify any issues that may have occurred due to changes or enhancements made to the software. The process verifies whether previous functionality still works as expected after any alterations have been made to the code or the product.

One of the most significant advantages of regression testing is that it helps to ensure that the changes made in one part of the system have no impact on any other parts. This means that the overall performance of the application is not affected, and the user experience remains consistent. It also ensures that there are no regression faults, which can cause major issues down the line.

By identifying any bugs or issues during the regression testing process, developers can take corrective measures and reduce the risk of future issues. This helps to increase the quality of the software, which ultimately leads to better user satisfaction.

In conclusion, regression testing is a pivotal part of the software development process. It ensures that the software continues to perform as expected, even after changes or enhancements have been made. The process helps to identify any issues, assess the overall risk of any code changes and reduce the chances of regression faults. It is an essential tool that allows developers to deliver high-quality software that meets the needs of their users.
