python - How to unit test Django rest framework requests? -

i have django-rest-framework api, want unit test. more specifically, want unit test data validation methods separately. these data validation methods request parameter, so:

def validate(request) 

in order test separately, need way create requests. in django-rest-framework, there apirequestfactory, can used in creating requests. main problem is, apirequestfactory not create same request django-rest-framework uses. instead, create regular django requests stated site:

note: when using apirequestfactory, object returned django's standard httprequest, , not rest framework's request object, generated once view called.

but because validation methods use django-rest-frameworks request, cannot unit test using apirequestfactory. there way unit test separately those, or should use apiclient, , try test whole apiview? wouldn't want that, because not pure unit test. , apiclient, can responses, not requests. why there not apirequestfactory django-rest-framework requests? mean, if ones used in django-rest, why request factory doesn't generate instead?

was able bypass not sending request validation method, instead request.data. way validation methods got independent on request, rely on data sent them.
