I've noticed, once or twice, when there were some updates pushed by Runscope, at times it didn't refresh the pages. I was running it, there were multiple tests running at the same time, and it didn't update the webpage I was looking at. So I had to refresh it manually. Occasionally, it still happens. Another thing I have found is that the built-in editor for the scripts can be improved a lot. Instead of making such a basic editor, maybe include a little more so it is easier to look at things and debug. Finally, other than the Runscope documentation, I haven't seen too much elsewhere. I haven't seen a user community.
