What is Regression Testing?

Regression testing is a procedure in which computer programmes are evaluated to ensure that the application or software continues to work and that any changes have no negative impact on its performance or functionality.

You know What is Regression Testing? Regression testing is an essential aspect of the software development process. Code testing professionals in larger businesses handle it. In general, applications or software are updated, or new features are added to improve performance, so regression testing involves re-testing old test cases used to test the previous version of the software in the latest version to ensure that the old performance and capabilities are still functional.

What Is the Purpose of Regression Testing?

The primary goal of regression testing is to ensure that no bugs or defects appear due to new modifications and that the further app modification has no detrimental influence on performance or functionality. As a result, regression testing can be used to find new defects that arise as a result of recent changes and unfavorable changes in functionality.

When to perform?

It is critical for a business or organization to determine the new software test and its creation. After any recent change to the programme, it should be undertaken to ensure that it is perfect and defect-free.

It can be undertaken when a flaw or defect has been discovered and addressed. However, this will be costly, so the frequency with which it is performed varies with each project.

In most circumstances, such as in a major organization’s project, it is done regularly, such as daily, weekly, monthly, or other periods, depending on the organization and the project’s requirement.

It should be performed whenever a new change in the software is introduced; however, as the number of updates increases, the cost and effort involved in manual testing increases rapidly; as a result, an automation tool is used to keep things moving and ensure that no additional resources are wasted.

Why ?

    1. It allows problems and bugs to be found quickly and easily, resulting in improved software performance following new changes. The cost is lowered due to early bug detection because if the bug is discovered later, a lot of resources are required to remedy it.
    2. When it is performed, there is a more significant probability of detecting a bug that happened as a result of the introduction of new software updates.
    3. It will assist in discovering unwanted side effects that are induced by a change in the operating environment, as there may be some issues with the software code in the new operating environment.


As we know what is regression testing – It is particularly useful in software development since the software is frequently changed. With regression testing, the bugs that arise as a result of these changes may be found and corrected. It also enables an organization to make drastic changes to its software while ensuring that no harm is done as a result of such changes.
