74,902 PointsCan `assertContains` produce false positives?
random question, but previously we used assertIn to find is something is in something else. With the response we specifically passed the context so that we could verify data being sent to the view / that the correct article was retrieved.
So my question is does assertContains have checks to prevent false positives when checking for X containing Y. What would happen if something is sent to the view in context, that was not output?

Treehouse Guest TeacherassertContains only checks against the text attribute of a Response object (HttpResponse and friends) so it doesn't care what's in the context because it doesn't know about the context at all.
But you do occasionally get false positives when you search for something that's easily contained in the output but isn't the thing you're looking for. Consider checking for a number of items, like 3, when your HTML contains an h3 tag.
