Django assert that response contains one of a list of possible strings

Question

I'm writing tests for my Django app using the built-in testing tools. Right now I'm trying to write a test for a page that displays a list of a user's followers. When a user has no followers the page displays a message randomly picked from a list of strings. As an example:

NO_FOLLOWERS_MESSAGES = [
    "You don't have any followers.", 
    "Sargent Dan, you ain't got no followers!"
]

So now I want to write a test that asserts that the response contains one of those strings. If I was only using one string, I could just use self.assertContains(request, "You don't have any followers.") but I'm stuck on how to write the test with multiple possible outcomes. Any help would be appreciated.

Answer 1

Try this:

if not any([x in response.content for x in NO_FOLLOWERS_MESSAGES]):
        raise AssertionError("Did not match any of the messages in the request")
