Then the "Article" content type should exist

Assert a content type exists, or does not, by its label, as listed on the content types administration page (/admin/structure/types), which is fetched with the current session so the page on screen is left alone.

Examples

Then the "Article" content type should exist
And the "Basic page" content type should exist
Then the "Blog post" content type should not exist
And the "Event" content type should not exist
Then the "Utility page" content type should not exist
