Regression testing is one of the most common ways to test software when it is being made. When new features, functions, or updates are added, regression testing is done to make sure that the old code hasn’t been broken in any way. The goal of Oracle regression testing is to make sure that an application still works the way it should after a change. Due to how often ERP programs are updated, regression testing is of the utmost importance.

What are the different kinds of regression testing for software?

Regression testing can be done in different ways, depending on the kinds of updates and changes made to an app.

  • Selective testing only looks for changes in certain parts of an application when doing regression testing.
  • Progressive regression testing is done when new features are added to make sure that none of the old code breaks.
  • Retest-all Regression tests are the last step in a project’s deployment, right before it is released. They are very thorough tests.
  • Partial regression testing is done when changes are made to the code base – a small part of the program is put through a series of tests to make sure it still works the way it should.
  • Unit regression testing makes sure that the functionality of each module is tested separately from its dependencies by isolating each module.

Is regression testing part of UAT?

UAT, which stands for “user acceptance testing,” is the last step in testing software. But regression testing is not part of UAT testing. If you want to make it less likely that users will reject your product, you should test this first.

What is a regression test suite?

A regression test suite is a group of test cases that have already been built and tested. In the quality assurance process, this could include everything from unit tests to full-stack integration tests.

What are the best ways to test for regression?

Regression testing can be done by manually or automatically running test scripts that have already been set up. When it comes to solving some problems, only automated testing can guarantee the highest level of accuracy and efficiency. Some problems can only be solved by a person’s ability to reason and test. For regression validation testing to work well and quickly, it is important to find the right balance between the two approaches.

When should regression testing be done?

Regression testing can be done at any point in the software development lifecycle. Most of the time, regression validation is used for:

  • Adding new features or capabilities to an existing system: Adding new features or capabilities could have a big effect on the current application, as well as any integrations and changes that have been made.
  • Want to connect to programs outside of your own: Changes to the code that are needed to add new integrations with third-party apps could stop working as expected on existing features.
  • When there is a new version of the program: ERP software providers must always do regression testing on their software to make sure that new updates don’t break upgrades and features that have already been released.


Regression testing is the same for an ERP as it is for any other packaged product. The best platform you can rely on for regression testing is Opkey. Because of its no-code test automation, it is so user-friendly that even non-technical users are able to automate their application testing within a matter of hours rather than months. Most of the time, regression testing is done before the first ERP deployment because this is when most changes are made. It’s also a good idea after launch, whenever new features or ways for apps to work together are added.
