Running tests on Mac OS X console using mono/nunit

Question

I have Max OS X 10.11.1 installed, with Xamarin on it. I wrote simple testing class, just to test running Nunit tests on Mac OS X & Ubuntu, class has literally one method which returns string:

using System;

namespace testing_project
{
    public class EmptyClass
    {
        public EmptyClass ()
        {
        }

        static void Main(string[] args)
        {
        }

        public string helloWorld()
        {
            return "Hello World!";
        }
    }
}

And I have a NUnit class to test my EmptyClass:

using System;
using NUnit.Framework;

namespace testing_project
{
    [TestFixture]
    public class EmptyClassTest
    {
        [Test]
        public void testHelloWorld()
        {
            EmptyClass empty = new EmptyClass();
            Assert.AreEqual ("Hello World!", empty.helloWorld ());
        }
    }
}

When I run this in Xamarin studio, test is passing just fine.

How can I achieve this on CLI?

Mono includes an install of NUnit's runner/console (version 2.4.8) that is called via a shell script called nunit-console:

cat `which nunit-console`
#!/bin/sh
exec /Library/Frameworks/Mono.framework/Versions/4.2.1/bin/mono --debug $MONO_OPTIONS /Library/Frameworks/Mono.framework/Versions/4.2.1/lib/mono/4.5/nunit-console.exe "$@"

So to run your tests from the CLI you can either call the NUnit's test .csproj or the CIL/Assembly:

MONO_IOMAP=all nunit-console nunit-lib/nunit-lib.csproj

or

nunit-console nunit-lib/bin/Debug/nunit-lib.dll

NOTE: NUnit console 2.4.x is broken due a hard-coded Windows-style Directory Separator when parsing .csproj files and creating the expected CIL/assembly location, use MONO_IOMAP to work around it. This is not a issue in NUnit runner 3.0.

Example:

nunit-console nunit-lib/bin/Debug/nunit-lib.dll
