Everything to Know About Regression Testing

-

Regression testing is one of the most familiar types of testing in software development. It is known as a regression test because it requires going back or “regressing” to any existing code to confirm it isn’t negatively affected whenever any new functionality, features, or updates are attached. Regression testing is essential in ERP applications due to the commonness of regular updates.

Regression testing in software development

The process of regression testing includes assessing any already-released software to evaluate that no functionality is destroyed; as a result of any transformation or improvement. Overall solidity and functionality of current features are assured by corrective regression testing.

Different types of regression testing

Seven different types of regression testing can be performed in the regression test, depending on the types of updates and changes made to any application:

  • Corrective regression testing 

It is a simple test used to test existing functionality when no modifications to the source code.

  • Re-test all regression testing 

It reruns all test cases whenever transformations are made to an application’s existing source code, such as a principal software update or a re-platform.

  • Selective regression testing 

Selective regression testing selects specific parts of an application to test the impact of new code on existing code.

  • Progressive regression testing 

It is performed when there are new components added to ensure existing code is not affected.

  • Partial regression testing 

It happens when transformations are made to any source code to verify that the application is still functioning as anticipated.

  • Unit regression testing 

It isolates distinct pieces of code to test so that any reliance on that do not influence the code.

When to Perform Regression Testing

Regression test at any phase of the software development lifecycle is interesting. The most ordinary times to perform regression validation include:

  • When adding a new feature or functionality: 

Introducing new features or functionality can negatively affect the present application and pre-existing integrations and customizations.

  • When a modification is done to the existing application: 

Even when tweaks or modifications can wreak mayhem on overall functionality. Transformations such as adding a new field or minor workflow adjustments can trigger the need for regression confirmation.

  • When integrating with other applications: 

New integrations with third-party applications need code modifications that can damage or disrupt previous functionality.

  • When there is a software update: 

Regular software updates like those stopped by agents require continuous regression confirmation to confirm previous updates and functionality are not affected by newer updates.

  • When there are performance issues: 

Whenever someone is experiencing performance issues, it can specify the problem areas causing those performance issues.

How to improve regression testing?

Effective regression testing techniques involve proper planning and the right automation tool. Creating the perfect regression test suite concerns the following steps:

  • Collecting all standard test cases and monitoring shifts carefully
  • Prioritizing test cases and estimating the time needed to run them
  • Investigating the changes and their effects on various components
  • Specifying the areas that are more helpless to risks and failures

Conclusion

‍Regression validation in Opkey gets the most use as the vendors roll out their latest updates. It happens on a much more frequent basis these days as corresponding to others. Stumbling to keep up with lots of developments is one of the many reasons why Opkey has decided to execute these automated regression programs. With the availability of these complex ERP integrations and customizations, the manual regression confirmation is quite overwhelming.
