 FormSet and QuerySet for some reason doesn't have a capitalized S in
 `assertFormsetError`  and `assertQuerysetEqual`, whereas all other
 instances of camel-cased names in the codebase containing either of them
 have capitalized S's: (InlineAdminFormSet, Base[...]FormSet,
 EmptyQuerySet, RawQuerySet).

 Looking at the other assertion methods inherited from `unittest.TestCase`
 they're incredibly cased (e.g. `assertMultiLineEqual`) so I'm not finding
 any convention of not uppercasing liberally.

 My suggestion is to rename `assertFormsetError`->`assertFormSetError` and
 `assertQuerysetEqual`->`assertQuerySetEqual` in `django.test.TestCase` and
 add aliases for the old names so as not to break existing code. In the
 code base this is a quite small change, but there's likely some docs (and
 e.g. the tutorial) that might warrant updating to new spelling. Could also
 (down the line) add a deprecationwarning to get rid of the old spelling if
 you want a cleaner API interface.

 This bit me as I was following the tutorial and re-typing the code instead
 of copy-pasting, so it's plausible that others might encounter it
 similarly if they don't have an IDE that suggests the alternate spelling.
