Steps to reproduce

I just executed test that had failure and it threw exception.

using NUnit.Framework;
using System;
namespace nunit24214asf
{
	[TestFixture()]
	public class Test
	{
		[Test()]
		public void TestCase()
		{
			Assert.AreEqual(3, 4);
		}
	}
}

Expected behavior

Either expect and handle null or change adapter/host(not sure which) to not send null for message text

Actual behavior

Null reference exception happens

Environment

This happened to me while I was implementing VSTest into VisualStudio for Mac and debugging vstest.console.exe built from master(commit sha1 9b92161).

@DavidKarlas : Can you please share the nuget package version of Nunit adapter and the target framework version of your test project.
Seems like a bug in our side and willing to have a local repro.

[DavidKarlas]

Whole configuration is still a bit in flux but I'm pretty sure Adapter is 2.0.0 and NUnit 2.6.4

Fixed!!!
