This document discusses RuntimeUnitTestToolkit, a tool for running unit tests on IL2CPP games. It allows creating unit test classes with public methods that will be automatically registered as tests. Tests can make assertions using the Is method and can be asynchronous by returning IEnumerator. It works with UniRx and allows testing asynchronous coroutines. The tool focuses on play time testing and supports running tests on actual devices.

3. UnitTest

4. MSTest or xUnit.net
xUnit.net
NUnit

5. Visual Studio UI
More multi functional

6. Standard on NUnit basedtool
But...

7. I want to run on IL2CPP

8. RuntimeUnitTestToolkit

9. Demo…

11. // make unit test on plain C# class
public class SampleGroup
{
// all public methods are automatically registered in test group
public void SumTest()
{
var x = int.Parse("100");
var y = int.Parse("200");
// using RuntimeUnitTestToolkit;
// 'Is' is Assertion method, same as Assert(actual, expected)
(x + y).Is(300);
}
}

12. public class SampleGroup
{
// return type 'IEnumerator' is marked as async test method
public IEnumerator AsyncTest()
{
var testObject = new GameObject("Test");
// wait asynchronous coroutine(UniRx coroutine runnner)
yield return MainThreadDispatcher.StartCoroutine(MoveToRight(testObject));
// assrtion
testObject.transform.position.x.Is(60);
GameObject.Destroy(testObject);
}
IEnumerator MoveToRight(GameObject o)
{
for (int i = 0; i < 60; i++)
{
var p = o.transform.position;
p.x += 1;
o.transform.position = p;
yield return null;
}
}

13. public static class UnitTestLoader
{
[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
public static void Register()
{
// setup created test class to RegisterAllMethods<T>
UnitTest.RegisterAllMethods<SampleGroup>();
// and add other classes
}
}

14. Conclusion

15. UniRx is supported by RuntimeUnitTestToolkit
Released in GitHub
https://github.com/neuecc/RuntimeUnitTestToolkit

16. Focus on play time test
Supports Asynchronous test
Actual machine test
