My task is to automate a WPF app using appium and Winappdriver. Inspect finds the various elements but Winappdriver doesn't. It turns out that someone in another team got a similar task and had no problems to automate. Now I suddenly have to explain why I was not able to do the same. Examples for Winappdriver automation work fine. So the basic system works. Just in my sut / target app there is nothing, that it can find. What could be reasons for this result? Shouldn't Winappdriver simply find everything that inspect can find? What can I do? Could it be missing assemblies? Dlls? Some Registry Entry? Windows Edition or Version?
