Automated testing is a process in which software tools execute pre-scripted tests on a software application. The purpose is to define repetitive tasks and create or modify a test automation framework allowing constant test execution, reporting and comparisons. This may greatly reduce your associated testing time and cost.

What if any developer, at any time, could check in a new build and kick off a complete regression test suite at will? Test more, earlier, and find errors before multiple build iterations, with increasing technology debt, stack up. Want to use agile techniques efficiently, particularly DevOps?

Some types of testing are just prohibitively expensive to do manually. Imagine an application that varies, in part, on the postal code: manual testing can only afford to test a handful of variations. Data-driven automation, though, could be fed a spreadsheet of interesting postal codes, and left to run overnight.
