Are you really doing agile test automation?
Here’s a simply way you can find out: if your automated test fails, who acts? Does your whole team immediately downs tools to fix the issue? Or do the QA folk own the failed build job, analyse the failures and raise defects if any of the failed tests correspond to actual bugs?
One approach is agile, the other is waterfall in disguise.
In this video, John Ferguson Smart compares these two approaches, and talk about what you need to do to adopt truly agile automation practices.
