Regression testing and its types

 

There are two methods for performing regression testing: manually and automatically. 

Contrarily, as human testing is now usually time constrained, automation is the best substitute. 

Regression testing can

 be carried out in a number of different methods, much like many other types of testing. 

In this post, we'll discuss the various regression testing approaches and how they could support general quality assurance procedures.

    

Regression Testing using Correction

Regression Correction 

When a product's specifications haven't changed, testing is often used. 

It is simple to modify existing test cases to run the necessary test.

All-Regression-Testing-Retest

Regression testing in this manner takes a lot of time and effort. 

QA teams come up with a plan for thoroughly testing a product while keeping the option to repurpose test cases in the event that no modifications have been made.

Putting Regression Testing First

Regression for a Reason Testing is done to determine the effects of adding new code to an existing software code base. If this procedure is followed, a subset of the current test cases can be used to decrease the time spent retesting and the amount of resources needed.

Testing for Progressive Regression

Periodic Regression When certain adjustments are made to the programme specifications and fresh test cases are created, testing becomes more efficient. This kind of testing guarantees that no features from a prior version have been harmed or damaged in the present one.

When several changes are made to existing code, thorough regression testing is advised. Additionally, this form of testing is carried out specifically when fresh modifications have an extended effect on the software's underlying code. The long-term benefits of using this strategy during QA can be enormous for the product. After this process is finished, users could be given access to the finished system.

Testing for Partial Regression

Testing for issues when new programmes are merged with existing code uses partial regression. To make sure a system keeps functioning correctly after new code is implemented, partial regression testing is used.

Testing for Individual Unit Regression

Regression using Units The most crucial component of unit testing is testing. It often takes place in solitude and focuses on unit codes. During testing, all additional interactions will be barred.

Conclusion

To make sure that updated code does not affect software functionality that was previously functional, various types of regression testing must be performed. Regression testing should only be performed by professionals because it is such a crucial component of quality assurance. According to current trends, companies may work with a stand-alone software testing agency. A pioneer in software testing is Sapizon Technologies.
