How can I bypass the Language request

Question

On each of my view I have a function that return the request language code of the browser. But when I run my unittest my views I have an error:

applications\emplois\views.py:74:

        """Return the user default language"""

def language_set(language):
    if "-" in language:
        return (language.split('-')[1]).upper()
    else:
        return language.upper()

class IndexView(generic.ListView):
    """

    return a list of Jobs

    template_name='emplois/index.html'
    context_object_name='latest_jobs_list'

    def language(self):
        """Return the user default language"""
        language = language_set(self.request.LANGUAGE_CODE)
        language = language.upper()
        return language

    def get_queryset(self):
        """

        greater than Now() and a default Language
        """
        #import ipdb;ipdb.set_trace()
        return Job.objects.filter(language=self.language(),\
              EXPIRYDATE__gt=datetime.now())\
            .order_by('EXPIRYDATE')

tests:

import pytest
from django.core import mail
from django.contrib.auth.models import AnonymousUser
from django.http import Http404
from django.test import RequestFactory
from mock import patch
from mixer.backend.django import mixer
pytestmark = pytest.mark.django_db

from applications.emplois import views


class TestIndexView:
    def test_anonymous(self):
        req = RequestFactory().get('/')
        resp = views.IndexView.as_view()(req)
        assert resp.status_code == 200, 'Should be callable by anyone'

How can I bypass the Language request because I don't use a browser

Answer 1

When you use a RequestFactory you can give the request any request parameters. In this case you are looking for the request.LANGUAGE_CODE so the solution is to set the LANGUAGE_CODE in your test's RequestFactory.

You can see the documentation for the RequestFactory here.

So solution is:

def test_anonymous(self):
    req = RequestFactory().get('/')

    # Here is the change.
    req.LANGUAGE_CODE = "en"

    resp = views.IndexView.as_view()(req)
    assert resp.status_code == 200, 'Should be callable by anyone'
