[Mono-list] Nunit hangs when testing a class using the GTK

[Wolfgang Schulze-Zachau]

I might be a bit ignorant here, so please bear with me.
I am running MonoDevelop 2 Alpha 2 on Fedora 9. In my project I use NUnit to
do all sorts of testing. Today I added a test for a class that is supposed
to create a popup menu on demand, which can then be displayed in a TreeView.
Here is the class code so far:


using System;
using Gtk;

namespace Amino.ProCos
{
	
	
	public class RootProjectTreeNode
	{
		
		public RootProjectTreeNode()
		{
		}

		public string DisplayName {
			get { return "All Groups"; }
		}

		public Menu getMenu() {
			Menu menu = new Menu();
			MenuItem expand, collapse, addgroup;
			expand = new MenuItem("Expand");
			collapse = new MenuItem("Collapse");
			addgroup = new MenuItem("Add Project Group");
			menu.Add(expand);
			menu.Add(collapse);
			menu.Add(addgroup);
			return menu;
		}
	}
}

And here is the relevant unit test code:

using System;
using Gtk;
using NUnit.Framework;
using Amino.ProCos;

namespace Amino.testProCos
{
	
	
	[TestFixture()]
	public class TestRootProjectNode
	{
		RootProjectTreeNode root;
		
		[Test()]
		public void Instantiation()
		{
			root = new RootProjectTreeNode();
			Assert.AreEqual("All Groups", root.DisplayName, "Instantiation of a the
root project tree node failed");
		}

		[Test()]
		public void BasicMenu() {
			root = new RootProjectTreeNode();
			Menu menu = root.getMenu();
			Assert.IsTrue(true, "No idea");
			MenuItem[] items = (MenuItem[])menu.Children;
			Assert.AreEqual(3, items.Length, "menu should contain 3 elements");
			Assert.AreEqual("Expand", items[0].Name, "First popup menu item is not
'Expand'");
			Assert.AreEqual("Collapse", items[1].Name, "Second popup menu item is not
'Collapse'");
			Assert.AreEqual("Add Project Group", items[3].Name, "Third popup menu
item is not 'Add Project Group'");
		}
	}
}

The whole thing compiles without problem. When I run the tests, NUnit hangs.
The only way out is to open a console and kill the NUnit process. The
console window from which monodevelop is started, shows error messages such
as this:

Unix transport error.

The last error is the one thrown by killing the process. I have no idea why
this is happening, so if anybody can point me in any direction, I would be
truly grateful.

cheers
