GameObject testing? Coroutine support?

[peterept]

I would dearly love a way to test game objects under the MonoBehaviour events (Start, Update), and this would be possible if we could use Coroutines within the unit tests themselves, in particular to delay a frame or period of time, to allow GameObjects to receive their events.

The current way we are doing it is "faking" the calls by using Reflection to call Start() and Update() on game objects to allow them to respond. However, this only works on single game objects that don't use many unity core features (such as Animations, etc).

My question is, how could we add Coroutine support to NUnitLite? I suppose each test would have to be an IEnumerator, or StartCoroutine on one.

Thanks

Seconded-- would love to see NUnit unit tests that support IEnumerator functions so I could call coroutines inside of them.

Have you considered Unity Test Tools?

I used those now, but they don't support Co-routines.

We ended up writing our own co-routine enumeration around tests that return IEnumerator.

I figured this out.

I put the code that uses a coroutine into its own class.

I then used Substitute (mocking framework that comes with Unity Test Tools) to mock the class that the coroutine was in.

Now all my unit tests work perfect.
