Touch.Unit getting closer to you

Have you noticed that:

• MonoTouch 5.1 (beta) is out ?
• MonoTouch.Dialog.dll is bundled within ??
• MonoTouch.NUnitLite.dll is also part of the package ???

What’s that ? It’s Touch.Unit main assembly, i.e. where the runner logic, UI and NUnitLite code resides. So it means you’ll get a unit test framework included with MonoTouch – almost no extra steps required.

Here are some quick instructions to get you going:

1. Start MonoDevelop
2. Create a new solution / project, e.g. Universal template, Empty Project and name it AppUnitTest;
3. Add a reference to: /Developer/MonoTouch/usr/lib/mono/2.1/MonoTouch.NUnitLite.dll
4. Open your AppDelegate.cs file and replace its content with:

using MonoTouch.Foundation;
using MonoTouch.UIKit;
using MonoTouch.NUnit.UI;

namespace AppUnitTests {

	[Register ("AppDelegate")]
	public partial class AppDelegate : UIApplicationDelegate {
		// class-level declarations
		UIWindow window;
		TouchRunner runner;
		
		public override bool FinishedLaunching (UIApplication app, NSDictionary options)
		{
			window = new UIWindow (UIScreen.MainScreen.Bounds);
			runner = new TouchRunner (window);

			// register every tests included in the main application/assembly
			runner.Add (System.Reflection.Assembly.GetExecutingAssembly ());

			window.RootViewController = new UINavigationController (runner.GetViewController ());
			window.MakeKeyAndVisible ();
			return true;
		}
	}
}

5. Create a new (empty C#) file, e.g. RegressionTest.cs, and paste the following code to replace its content:

using System;
using NUnit.Framework;

namespace Fixtures {
	
	[TestFixture]
	public class Tests {
		
		[Test]
		public void Pass ()
		{
			Assert.True (true);
		}

		[Test]
		public void Fail ()
		{
			Assert.False (true);
		}

		[Test]
		[Ignore ("another time")]
		public void Ignore ()
		{
			Assert.True (false);
		}
	}
}

6. Build and execute

Can it get better ? Yep! Once the next release of MonoDevelop becomes available you’ll have templates to create a unit test project and unit test fixtures (files).
