Implementation of a strong automated testing solution requires detailed knowledge and the input of talented test automation architects and engineers. These resources can not only configure a robust solution but determine which areas of testing can benefit most from automation, such as stress testing, functional testing, structural testing, and more. New changes also affect the scripts for regression testing, so even that classic automation example requires a lot of updating in agile. That amount of work warrants consideration when a development team is trying to figure out where to invest resources. Even as automated suites become more sophisticated, they still require human drivers.<\/p>\n
