Previously in the feedback item link below, it was mentioned that Test Studio needs to a better merge tool. Comparing Tests in Visual Studio is very difficult because the tests are all in one line. Similarly, the Test Lists comparison looks like this screenshot. It is difficult to actually see a difference in this side by side view shown in the screenshot. Like Konstantin Petkov said in the feedback item, it would be awesome if the tests can be compared at the step level. http://feedback.telerik.com/Project/161/Feedback/Details/88296-new-json-format-for-tests-is-really-hard-for-merge-compare
