I am running a test in the UI and as I watch the browser, the test steps are executing okay and the UI marks the steps as successful (with the white check in the green circle), but Test Studio seems to think there is some kind of error and after the UI completes, all the steps are marked as not run (with the white dash in the black circle) and the test is marked as failed.
I tried rerecording the test steps and running them again and got the same result, although the logs don't look the same. I've attached the logs from both runs. The first log included the DOM, which I removed. If you need the DOM included, let me know.
Test Studio version: 2015.2.273.0
Browser: IE 11, Version 11.0.9600.17959
Windows 7 Enterprise, Service Pack 1
