What is the relative path root of DeploymentItemAttribute?

Question

Using MSTest, what is the relative path root of the DeploymentItemAttribute.

Answer 1

To assume that the RelativePathRoot default is the dir where your solution resides was not correct in my case, nor was RelativePathRoot defined within my .testrunconfig file. I found the RelativePathRoot default to be the /bin/debug dir for the solution.

Walking back from that point, then walking up to my file that I was attempting to deploy for the unit test worked fine.
