`MonoBehaviourTest` is a [coroutine](https://docs.unity3d.com/ScriptReference/Coroutine.html) and a helper for writing [MonoBehaviour](https://docs.unity3d.com/ScriptReference/MonoBehaviour.html) tests.
Yield a `MonoBehaviourTest` when using the `UnityTest` attribute to instantiate the `MonoBehaviour` you wish to test and wait for it to finish running. Implement the `IMonoBehaviourTest` interface on the `MonoBehaviour` to state when the test completes.
## Example
```c#
[UnityTest]
public IEnumerator MonoBehaviourTest_Works()
{
yield return new MonoBehaviourTest<MyMonoBehaviourTest>();
}
public class MyMonoBehaviourTest : MonoBehaviour, IMonoBehaviourTest
{
private int frameCount;
public bool IsTestFinished
{
get { return frameCount > 10; }
}
void Update()
{
frameCount++;
}
}
```
## MonoBehaviourTest<T>
This is a wrapper that allows running tests on `MonoBehaviour`scripts. Inherits from [CustomYieldInstruction](https://docs.unity3d.com/ScriptReference/CustomYieldInstruction.html).
| `T component` | A `MonoBehaviour` component created for the test and attached to the test’s [GameObject](https://docs.unity3d.com/ScriptReference/GameObject.html). |
| `GameObject gameObject` | A `GameObject` created as a container for the test component. |
| `bool keepWaiting` | (Inherited) Returns `true` if the test is not finished yet, which keeps the coroutine suspended. |
## IMonoBehaviourTest
An interface implemented by a `MonoBehaviour` test.
