Question

Why if I run python manage.py test appname in my terminal is: Ran 0 tests in 0.000s OK

This is my tests.py:

from django.test import TestCase
import appname.factories

class UserProfileTest(TestCase):
    def sample_data(self):
        for i in range(0, 10):
            user = appname.factories.UserProfileFactory.create()

My models.py:

from django.db import models

class UserProfile(models.Model):
    street = models.CharField(max_length=250)
    tel = models.CharField(max_length=64, default='', blank=True)
    postcode = models.CharField(max_length=250)

    def __unicode__(self):
        return self.tel

My factories.py (factory boy):

from appname.models import *
import factory


class UserProfileFactory(factory.Factory):
    FACTORY_FOR = UserProfile

    street = factory.Sequence(lambda n: 'Street' + n)
    tel = factory.Sequence(lambda n: 'Tel' + n)
    password = 'abcdef'

Answer 1

Your individual test functions should begin with the word ‘test’.

You need to change the function def sample_data(self): to def test_sample_data(self):

The test runner will look for any classes in a file called tests.py, which sit in the root of your app, and which extend unittest.TestCase. Then it will run any functions within that class which begin with the word test (plus one or two other functions such as setup())

I’m probably being obtuse, but I couldn’t see anything in the main django testing docs stating that functions must begin with the word test. Anyway, there’s a reference to the requirement in this (official) tutorial.
