Subject Re: Why the use of Utils.Paths in TestBackwardsCompability?
Date Sun, 29 Jul 2012 18:43:49 GMT
to explain further, the shadow copy feature basically copies the test
assemblies to a different location and executes them from that location.
 However, to my knowledge it does not copy the file resources. The location
of where a test assembly is located and execute is not guaranteed which
makes using relative paths fickle, but its required cause obviously we can
exactly hard code paths.

Shadow copy breaks using relative paths in test code.  However if you turn
shadow copy off, then it kills the workflow of writing tests from within
visual studio since the test assembly is seen being used by another process
and blocks VS from rebuilding the test assembly which can be really
frustrating as you would imagine.

The thing to do is attempt to account for all situations so that people can
download on whatever box using whatever test tools with as little friction
as possible. I'm open to suggestions.
