Unit testing for MonoBehaviours

Questions & Answers
1

I’d like to add unit testing to my scripts that derive from MonoBehaviour. But I’m having trouble implementing it. I’ve tried NUnit and currently I’m trying out NUnitLite, but in the end it doesn’t really matter what library I use. I just want some unit tests for my MonoBehaviour scripts. I have no problem testing other classes, just the MonoBehaviour derivatives refuse to cooperate.

My question: Is it even possible to unit test MonoBehaviours? If so, how?
Thanks for reading about my issue.

All right, so I figured something out. Here’s what I did if anyone else has same issue.

I downloaded SharpUnit and it works, but not how I first expected. Instead of adding [Test] attributes above your class functions directly. You’ll need to create a new separate class that inherits SharpUnit’s TestCase, with this class you’ll load your Mono game object and perform tests on it.

With Unity 5.3.1 you can do the following:

using System;
using UnityEngine;
using NUnit.Framework;

[TestFixture]
public class TileFacadeTest
{
[Test]
public void TestFacade()
{
GameObject gameObject = new GameObject();
TileFacade tileFacade = gameObject.AddComponent();
tileFacade.tileValue = 1;
Assert.AreEqual(tileFacade.tileValue, 1);
}
}
