I think you should give some info about installing NUnit aswell, took me 1 hour searching tuts to get that working and understand how it works.

RoeEngine2UnitTest.RoeEngineTestCases (TestFixtureSetUp):
System.BadImageFormatException : Could not load file or assembly ‘RoeEngine2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. An attempt was made to load a program with an incorrect format.

VS 2008 Pro (and possibly standard) editions now support XNA and Unit Testing.

To use the features, make sure you add a new Visual C# > Test > Test Project into your solution, rather than a generic C# class library.

After you create the test with Kabal’s code, you can use the Test menu (Between tools and window) and select Run > Tests in Current Context (or Run > All Tests in Solution) to initiate the testing procedures.

Microsoft.VisualStudio.QualityTools should already be added as a reference but I include it just in case. It is important that you create a Test Project, not a generic project or VS will not register the tests.

Thanks to Roecode for this awesome engine code.

Here’s an example of the FpsCounter test: (I changed some namespaces around)

using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using NUnit.Framework;

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Engine.Components;

namespace UnitTests
{
[TestFixture]
public class FpsCounterTest : Microsoft.Xna.Framework.Game
{
private static FpsCounter _fpsCounter = null;
private int loopCounter = 0;

public FpsCounterTest()
{
Initialize();
}

[SetUp]
protected void SetUp()
{
_fpsCounter = new FpsCounter(this);
Components.Add(_fpsCounter);
}

[Test]
public void CounterTest()
{
_fpsCounter.Updated += this.Updated(null, null);
this.Run();
}

private EventHandler Updated(object o1, object o2)
{
return null;
}

#region Inherited Methods
protected override void Initialize()
{
}

protected override void LoadContent()
{
}

protected override void UnloadContent()
{
}

protected override void Update(GameTime gameTime)
{
_fpsCounter.Update(gameTime);
}

protected override void Draw(GameTime gameTime)
{
base.Draw(gameTime);

// This is the new, but temporary line of code.
loopCounter++;
if (loopCounter >= 20)
{
Assert.AreEqual(_fpsCounter.FPS, 0);
this.Exit();
}
}

#endregion
}
}

In components, a lot of your code is in the update method, so this should be ran and tested. This will allow you to do that.

but i still could not resolve (the type or namespace name ‘RoeEngine2′ could not be found (are you missing a using directive or an assembly reference?)).

thank for any help you can provide.

Btw, nice guide.
