Regression test cycle has grown to the point that manual testing takes too much time and a regression test suite is hard to maintain. This is why you should automate routine testing. By doing so, you’ll be able to quickly provide development teams with critical feedback, reduce time to market, improve product quality, and reduce overall costs. Automated testing provides you with the luxury of running enough exploratory, usability, and acceptance testing against the latest builds, searching for unusual or unexpected behavior of the system.
There are multiple approaches and tools, both open source and paid that you can use to automate your testing. But, it’s worth noting that choosing a tool is just the beginning of the process. You also need the right strategy and the right resources to administer the process.
