An essential step in the software development process is regression testing. It entails re-running both the functional as well as the non-functional tests to ensure that software that has already been developed and tested stays operational following an update. The purpose is to catch any bugs introduced due to code changes and ensure the application’s integrity. Manualregression testingcan be tedious and time consuming. With continuous integration and frequent code changes, doing regression testing manually may not be feasible. This is where test automation provides significant benefits. Here are 5 key reasons why regression testing automation is worth considering:

1. **Enhanced Productivity**

Automated testing can be run significantly quicker than manual tests. Once test scripts are created, they can be reused over multiple testing cycles. This improves overall efficiency and productivity of the testing team. Automated regression testing is especially useful with iterative and agile development cycles. New code changes can be regression tested frequently and efficiently. Issues can be caught early before they propagate further.

2. **Better Test Coverage**

Automated testing makes it possible to run more tests in less time. More areas of an application can be covered compared to manual testing. Higher test coverage translates to more bugs caught. Test automation also makes it easy to do data-driven testing with different inputs and test data combinations. Such extensive testing is difficult to perform manually.

3. **Reliability**

Automated tests perform precisely the same steps each time they are executed without any deviations. Manual testing can be inconsistent due to human errors such as oversight, fatigue or misunderstanding of test cases. Test automation avoids any variability in test execution. Automated regression tests can be seamlessly integrated into CI/CD pipelines and scheduled to run automatically with each code change. This ensures standardized, repeatable and reliable regression testing on every code iteration.

4. **Improved Accuracy**

Automated tests perform testing exactly according to the scripts and test data provided. The results are accurate and unbiased as there is no human judgment involved. In manual testing, test results can vary based on the tester’s subjective understanding and interpretation of test cases. There is always some room for human error and oversight in manual testing. Automated regression testing eliminates ambiguities and gives definitive pass/fail results based on expected outcomes coded into the scripts. Automated tests offer superior accuracy over manual tests by executing in a planned, controlled and consistent way.

5. **Better Risk Coverage**

Critical and complex test cases are prime candidates for automation. Automating these first provides good risk coverage. Tests that are tedious or difficult to perform manually can be automated, allowing for frequent and reliable execution. This improves overall risk coverage of the application under test.

 **Conclusion**

Regression test automation brings speed, consistency, and comprehensiveness to the testing process. Opkey’s no-code platform enables customers to quickly convert manual tests into scripts that are automated. Non-technical employees may quickly and easily create regression test cases without coding due to its drag-and-drop interface. With over 30,000 pre-built test accelerators, Opkey’s library expands coverage across more than 12 ERPs right from the start. Tests are automatically recommended by change effect analysis following system changes. Self-healing scripts reduce maintenance by 80% by fixing errors with a single click. After every release, end-to-end testing makes sure there are no regressions by validating customizations and integrations. Businesses such as Just Group have used Opkey to optimize coverage and cut regression testing timeframes by 68%. So, use Opkey to expedite releases and reduce QA expenses.
