I set up my test environment for PlayMode testing.
Tests marked with [Test] work just fine, e.g. if my code looks like:
using NUnit.Framework;
using UnityEngine;
using UnityEngine.TestTools;
namespace Tests
{
    public class WinTestSuite
    {
        [Test]
        public void WinTestSuiteDummy()
        {
            Assert.IsTrue(false);
        }
    }
}
... and then run all tests, the Test Runner output looks like:
(as expected)
Tests marked [UnityTest] seem to automatically pass without running, though. If I edit my test suite to look like this:
using System.Collections;
using NUnit.Framework;
using UnityEngine;
using UnityEngine.TestTools;
namespace Tests
{
    public class WinTestSuite
    {
        [UnityTest]
        public IEnumerable WinTestSuiteDummy()
        {
            Debug.Log("Hello world");
            yield return null;
            Assert.IsTrue(false);
        }
    }
}
The output I'm seeing is:
Looks like it isn't even running (can't see the Hello world anywhere), but I'm getting passing marks. What am I doing wrong?
