Description
In the case the form is actually valid, then assertFormValid(form) is no different to assertTrue(form.is_valid), however when the assertion fails it should print some helpful output about which fields have validation errors and what those errors are. Even just outputting errors.as_json would help a lot. I've implemented code along the lines of this many times.

After detailed analysis provided by David we decided to close this as wontfix:
- expecting a user to pass in all the requirements to pass the
ValidationErrorequality test is too hard to be useful, - the currently proposed
codemethod isn't that robust, there may be too many caveats for it to be useful, e.g. custom user errors generated where passwords don't match are unlikely to have a code passed into theValidationError, - if it's just pass/fail that isn't much benefit from
self.assertIs(form.is_valid(), True),
In the end, this isn't worth adding extra functions.
