Hi Anshoo,
I apologize for my previous message (on your site). It was my mistake and I found its reason.
In my country exists a proverb: "Morning is smarter than evening". This morning, when I woke up, I understood at once the reason of this behavior.
The reason of that behaviour was because I called the NUnitOrange.exe in the code of method, which was marked by the [OneTimeTearDown] attribute. But at this case the TestResult.xml was not created still! Therefore second, third, etc calls was looked like it "works fine", because their used the TestResult.xml file, which was created by previous session of tests executing.
I fixed it now, also I fixed my video.
Thank you for your work, Anshoo! It is very usefull program. Also I updated it on your new version, which you linked before.
Best regards, Andrey.
