There's kindof a test for it because tests fail without it :)

I should add a comment. It's because the old view overrode the `get_template_names` method and returned just a string, but the method in the superclass returns a list. That method is documented as returning either a string or list of strings. Our `render` function doesn't support checking for multiple templates and rendering the first one it finds like the django one does. So this is just a short-circuit of that. I guess I could test that no exceptions are raised if you send the render method a list or a string. What do you think?
