Testing Flask routes do and don't exist

I'm creating a large number of Flask routes using regular expressions. I'd like to have a unit test that checks that the correct routes exist and that incorrect routes 404.

One way of doing this would be to spin up a local server and use urllib2.urlopen or the like. However, I'd like to be able to run this test on Travis, and I'm assuming that's not an option.

Is there another way for me to test routes on my application?
