I'd just stack load, load_cube, load_cubes, load_raw and check they all call ```load_http```. I'd also change the url to include a port number e.g. ```http://geoport.whoi.edu:80/thredds/dodsC/bathy/gom15``` and have a ```self.assertEqual()``` in your ```load_http()``` to verify the url gets through in one piece. I suggest this only because of the splitting and joining that goes on between the top-level ```load``` call and the ```load_http```.
