    I am trying to log assertions but cannot figure out what I am doing wrong.

    Code (CSharp):
    1.         [UnityTest] //works
    2.         public IEnumerator LogMessage()
    3.         {
    4.             LogAssert.Expect(LogType.Log, "message");
    5.             Debug.Log("message");
    6.             yield return null;
    7.         }
    8.  
    9.         [UnityTest] //works
    10.         public IEnumerator LogError()
    11.         {
    12.             LogAssert.Expect(LogType.Error, "error");
    13.             Debug.LogError("error");
    14.             yield return null;
    15.         }
    16.  
    17.         [UnityTest] //not working
    18.         public IEnumerator LogException()
    19.         {
    20.             LogAssert.Expect(LogType.Exception, "");
    21.             Debug.LogException(new Exception(""));
    22.             yield return null;
    23.         }

    I have just been looking into this and this is what I found works:

    Code (CSharp):
    1.         [UnityTest]
    2.         public IEnumerator ExampleExceptionTest()
    3.         {
    4.             LogAssert.Expect(LogType.Exception, "Exception");
    5.             Debug.LogException(new Exception(""));
    6.             yield return null;
    7.         }
    The
    LogAssert.Expect
    needs to have the correct string, or it fails. This can be a matter of trial and error - I've ended up copy-pasting them from the Unity Console.

    Also if the execption is e.g. of type
    ArgumentOutOfRangeException
    the exception message is over two lines. In this case the line break characters I have found to work are
    \r\n
