What Is Automated Regression Testing?

Automated regression testing is a software testing technique that uses automated scripts and tools to verify that existing application features continue to function correctly after code changes, bug fixes, system upgrades, or new releases.

Regression tests are typically based on previously defined test cases. These tests are executed against the updated application, and the actual results are compared with the expected results. Any differences are recorded for further investigation.

For example, when an organization upgrades its SAP S/4HANA environment, testers may need to verify that purchasing, sales, finance, inventory, and reporting processes continue to operate as expected. Automated regression tests can help validate these workflows repeatedly and consistently.
