I have a class which uses JSNI to retrieve JSON data stored in the host page:

protected native JsArray<JsonModel> getModels() /*-{
    return $wnd.jsonData;
}-*/;

This method is called, and the data is then translated and process in a different method. How should I unit test this class, since I'm not able to instantiate (or seemingly mock?) JsArray?

What is the best way to unit test JSNI methods at all?
