vstest: dotnet test does not discovers tests (xunit + mac)

From @RassulYunussov at https://github.com/dotnet/cli/issues/5949

Interesting thing happening when I add xunit tests to my project. When I start test using command: dotnet test within Visual Studio Code Terminal - everything goes ok. All tests run. But when I run dotnet test from a terminal (without Visual Studio Code) I get error message that says that there is no test available.

Steps to reproduce

dotnet test

Expected behavior

(within Visual Studio Code) Build started, please wait… Build completed.

@smadala I can confirm that adding ulimit -n 4096 to /etc/profile fixed the issue for me. This is a reasonably simply workaround until the issue is fixed in xunit.

FWIW, I can confirm this bug. I have a build failing on my Mac locally, but builds fine on a Linux based Jenkins box.

Mac Version: 10.12.3 (16D32)

$ dotnet

Will dig into it a bit deeper once I have some time.

@rnowosielski Can you try increase max limit for number of open files per process, Eg: By adding ulimit -n 4096 to /etc/profile.
