Benefits and Types of Regression Testing

The enterprises of the present digital world are effectively in need of applications to enhance their visibility and productivity. During this application building process, the products undergo several modifications apart from the already listed requirements.

And, this way of performing frequent changes can lay down several defects and cause many challenges to the already existing functionalities.

This exclusively calls the need for regression testing to validate if the changes made to the application are not affecting the already existing functionalities of the software.

Regression testing is one of the very essential software testing types for re-executing the test cases and validating if the latest changes made to the application have not affected the already existing functionalities of the software application.

There are several benefits with regression testing such as:

• Helps in identifying bugs and defects
• Assures the development of quality software before production
• Verifies if the latest changes made to the application are not affecting the existing functionalities
• Increases the process of testing and decreases the testing lifecycle
• Encourages continuity of business operations, etc.

7 Types of Regression Testing

Well, there are 7 different types of regression testing and these are used based on requirements.

• Selective Regression Testing: This is practiced for analyzing how the newly added code can impact the code that is already available in the software.
• Progressive Regression Testing: This testing practice efficiently helps when there are certain changes or new test cases designed in the program.
• Partial Regression Testing: This testing type is practiced when the addition of new code causes issues to the already existing code.
• Complete Regression Testing: This testing type is effectively practiced when there is a huge impact on the software’s root code due to new changes.
• Corrective Regression Testing: This testing type is practiced when there are no modifications or changes in the product’s specification.
• Unit Regression Testing: This is one of the important testing types. The focus is more on the coding unit and the rest of the interactions and dependencies are blocked.
• Retest-all Regression Testing: This is a time taking process as it involves testing the product’s aspects and reuses all the test cases even when there isn’t any change made to the product.

The need for regression testing is huge for applications that are having constant modifications. As mentioned above, adopting the practice of regression testing helps in many ways. Leverage Regression testing services from next-gen testing service providers for a perfect architecture of the application before its launch.
