One of the fundamental processes in software development and maintenance is regression testing. This testing guarantees that once changes or new features are implemented, the existing ones will still function correctly. The process is often carried out manually. But, in addition to being labor-intensive, it is also prone to mistakes.

That is why many teams prefer automating the procedure, as automation provides multiple benefits to any software development project. We’ll talk about the advantages of regression test automation in this blog post, as well as why it’s becoming more and more important for contemporary development teams.

Increased Test Coverage and Accuracy

The essence of automated regression testing lies in the ability to repeatedly and consistently perform testing of all critical paths and scenarios. As practice shows, it is difficult to provide such coverage when using manual methodologies due to the lack of time, material, and human resources.

Cost-effective and Time-saving

The most important advantage of regression test automation is the economy of time and money. Manual regression testing is massively laborious, and takes much time and human resources, particularly with huge and sophisticated software applications. Automated regression testing allows software development teams to run tests faster and more efficiently, thus freeing up humans to do more important and challenging things like build new software or innovate solutions.

Early Detection of Defects

Another way of explaining this is that regression test automation helps software teams identify and rectify errors at the start of the development process, at which point they have no means of propagating and are less expensive to rectify. With automated regression examinations integrated with the CI/CD pipeline, more severe bugs can be identified and resolved the moment they appear, reducing the possibility of releasing unhealthy software to customers.

Improved Software Quality

Automation of regression testing helps the software teams maintain applications at the required quality level at all times. The automated test scripts can be run regularly or after even a small code change to get quick feedback on potential problems or regressions.

Scalability and Maintainability

The number of test cases that must be covered to adequately conduct a complete regression test skyrockets as software applications become more and more complicated and add functionality. Managing and manually running the test becomes unmanageable.

Parallel Execution and Faster Feedback

Most of the new and modern regression test automation frameworks and tools offered in the market come with parallel execution support. This will help run multiple test cases simultaneously with different machines or environments, which will significantly reduce the total test execution time.

Conclusion

Regression testing is being revolutionized by Opkey; a test automation platform driven by artificial intelligence. For enterprises, this platform drastically cuts expenses, labor, and time-to-market. Test cases may be easily created by business users and QA analysts because of its user-friendly, no-code interface. More than 30,000 ready-to-use test cases covering more than 12 ERP systems are pre-loaded onto the platform, allowing regression test coverage to grow quickly.

It suggests and ranks pertinent test cases in accordance with its change impact analysis capabilities, which offer insights into how application modifications affect business operations. Additionally, Opkey uses self-healing script technology, which minimizes maintenance efforts by over 80% by automatically mending test scripts in the event of failures. This feature enables users to fix faulty tests with a single click.
