Highly WIP, I'm test-driving a test framework in a language I don't know :-)

CSharpTestFramework.cs

using System;

namespace CSharpTestFramework
{
	class MainClass
	{
		private uint run;
		private uint failures;
		
		delegate void Test();
		
		class TestGroup
		{
			public string Status()
			{
				return "";
			}
		}
		
		private void RunTest(Test test)
		{
			run++;
			try {
				test();
			} catch (Exception ex) {
				failures++;
			}
		}
		
		private void RunPassingTest()
		{
			
			RunTest(() => { });
		}
		
		private void RunFailingTest()
		{
			RunTest(() => { throw new Exception(); });
		}
		
		public void Run()
		{
			RunPassingTest();
			RunPassingTest();
			RunFailingTest();
			
			RunTest(
				() => {
					var testGroup = new TestGroup();
					if(testGroup.Status() != "0 run, 0 failures")
						throw new Exception();
				}
			);
			
			Console.WriteLine(String.Format("{0} run, {1} failures", run, failures));
		}
		
		public static void Main (string[] args)
		{
			MainClass main = new MainClass();
			main.Run();
		}
	}
}
