* testing with empty text node.
* run: Set a function object which run something modifying the editor (or
* does nothing).
* expectedUndoResult: Set an expected innerHTML result as string or array
* of the string. If this is not specified, it's compared
* with editorInnerHTML value.
* cleanUp: Set a function object if you need to clean something up after the
