best method to mock http request without use of url in django

I have 2 class like below I don't have url path for class A what is the best method to test process_get? I tried mocking a http request with request in rest_framework.request but they don't let me set query_params witch i need to set

class A(APIView):
     def process_get(self, request, form):
       pass

class B(A):
  def get(self,request)
    pass
