Coverage test django admin custom functions

Question

I created a custom functions in django admin.py and im trying to test the using coverage :

class Responsible(admin.ModelAdmin):

   """
    Inherits of admin class
  """

   list_display = ('user', 'Name', 'last_name', 'process',)
   search_fields = ('p__name', 'user__username')

   def User_Name(self, obj):
       return obj.user.first_name

   def User_Last_Name(self, obj):
       return obj.user.last_name

Responsible model has a django user model foreign key...So far i tried a lot of ways to test:

class AdminTestCase(TestCase):

    fixtures = ["initial_data.json"]


    def test_first_name(self):
        rsf = Responsible.objects.get(id = 1)
        User_Name(rsf)

    def test_first_name2(self):
        self.obj = Responsible.objects.get(id = 1)

But nothing works....any help please ?

Thanks in advance !!

You will have to use django client and open list page for Responsible model in django admin.

https://docs.djangoproject.com/en/1.10/topics/testing/tools/#overview-and-a-quick-example

By opening admin list page your custom functions will be called and hence will covered under tests.

So basically something like below needs to be done:

from django.test import Client, TestCase

class BaseTestCase(TestCase):
    """Base TestCase with utilites to create user and login client."""

    def setUp(self):
        """Class setup."""
        self.client = Client()
        self.index_url = '/'
        self.login()

    def create_user(self):
        """Create user and returns username, password tuple."""
        username, password = 'admin', 'test'
        user = User.objects.get_or_create(
            username=username,
            email='admin@test.com',
            is_superuser=True
        )[0]
        user.set_password(password)
        user.save()
        self.user = user
        return (username, password)

    def login(self):
        """Log in client session."""
        username, password = self.create_user()
        self.client.login(username=username, password=password)


class AdminTestCase(BaseTestCase):

    def test_responsible_list(self):
        response = self.client.get('/admin/responsilbe_list/')
        # assertions....

Thanks for your answer, never done that...could you give me an example in your answer for the first function called "User_Name" ? – jsanchezs Nov 21 '16 at 16:24
Updated answer. – Falloutcoder Nov 21 '16 at 16:37
I appreciate your help, but i think that's not exactly what i need, i already tested login and logout...what i need is to test those functions i posted – jsanchezs Nov 21 '16 at 16:46
`def test_responsible_list(self):` will test it. By opening the list page in admin for your model `Responsible`, done by `self.client.get('/admin/responsilbe_list/')` will eventually call your admin custom methods. – Falloutcoder Nov 21 '16 at 16:48
I found another way, i voted you up anyway for your help and guidance. Thanks !! – jsanchezs Nov 21 '16 at 20:05
too long way for such easy task. Just import admin class, then in TestCase test its custom functions as plain and simple as any function. – Alex V Feb 12 '19 at 15:04

Actually i found it, and it was quite simple if someone ever need it :

def test_first_name_admin(self):
    rsf = ResponsibleStateFlow.objects.get(id = 1)
    ResponsibleStateFlowAdmin.User_Name(self, rsf)
    ResponsibleStateFlowAdmin.User_Last_Name(self, rsf)

Complete, fast and easy:

from [your-app].admin.py import Responsible  # better name it ResponsibleAdmin

class AdminTestCase(TestCase):

fixtures = ["initial_data.json"]


def test_first_name(self):
    r = Responsible.objects.get(id = 1)
    admin_function_result = Responsible.User_Name(Responsible, obj=r)
    self.assertEquals(admin_function_result, r.user.first_name)  # alternatively, pass first_name as string

No need to use admin logins. Test plain functions as plain functions.

The custom function needs an object derived from the queryset of the view. This should work.

from django.contrib import admin

from myapp.admin import ResponsibleAdmin  # renamed to distinguish from model class

class AdminTestCase(TestCase):

    fixtures = ["initial_data.json"]  # as in the question

    def test_first_name(self):
        r = Responsible.objects.get(id=1)
        r_admin = ResponsibleAdmin(Responsible, admin.site)
        obj = r_admin.get_object(None, r.id)
        admin_first_name = r_admin.User_Name(obj)
        self.assertEquals(admin_first_name, r.user.first_name)
