Class UnityOneTimeSetUpAttribute

The UnityOneTimeSetUp and UnityOneTimeTearDownAttribute attributes are identical to the standard OneTimeSetUp and OneTimeTearDown attributes, with the exception that they allow for IEditModeTestYieldInstruction. The UnityOneTimeSetUp and UnityOneTimeTearDown attributes expect a return type of IEnumerator.
