Just enough to test a Windows UI

Here's just enough code to test a Windows Form. Put this in a Class Library project called Tests which references the DLL or EXE with the form in. The Tests project will need to reference System.Windows.Forms.

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using Dunwoody;
using NUnit.Framework;

namespace Tests
{
    [TestFixture]
    public class UITests
    {
        Form1 m_f;
        [SetUp]
        public void SetUp()
        {
            m_f = new Form1();
            m_f.Show();
        }
