Re: Testing if a view have an html element with at least one attribute

Oh, sorry. A bit of misunderstanding and miscommunication on my part.

The exemple I gave is just a quick way to reproduce my problem. The
real test use self.client, reverse, cast response.content to a string.
What I gave is a minimal exemple.

Also, I assumed you talked about comparing bit of html element, not
the raw content returned by the view. I'm quite uneasy to have the
test failing if a class is added or removed from the element. But yes,
your solution work for the current state of the application.
