I'm using Xamarin on a daily basis since more than 3 years now, always on a Mac with MonoDevelop/Xamarin Studio. It's not as comprehensive as Visual Studio with ReSharper, but it does its job.
But one thing is really bothering me, and it doesn't seem to get any better: Support for automatic tests is totally broken from my point of view. Not in a pure technical sense, because you get nunit tests eventually to run somehow. It's mainly the details that make it nearly unusable to me.
After all even the default test runner of Visual Studio is way better than everything here. I can't imagine how people at Xamarin are developing software. Without tests? Or without Xamarin Studio? Both would be far from ideal ...
So, now that I did complain a lot, I am wondering if I am the only one who desperately is looking forward to some improvements here.
PS: I am using the stable channel, so everything is related to the latest stable bits.
