Recently, I was assigned to fix a test suite which would consistently fail to run all 600 tests after consecutive 5 time-out ones. Now I am quite sure the AutoRefreshDomTree and AutoWaitUntilReady could result in some dead loops by chance.
An article was published on http://www.codeproject.com/Tips/895632/Tips-with-Telerik-Trouble-shooting and I hope that could be helpful for Telerik to improve their powerful testing framework.
