class SharedModuleStoreTestCase(TestCase):
"""
Subclass for any test case that uses a ModuleStore that can be shared
between individual tests. This class ensures that the ModuleStore is cleaned
before/after the entire test case has run. Use this class if your tests
set up one or a small number of courses that individual tests do not modify.
If your tests modify contents in the ModuleStore, you should use
ModuleStoreTestCase instead.
How to use::
from xmodule.modulestore.tests.django_utils import SharedModuleStoreTestCase
from student.tests.factories import CourseEnrollmentFactory, UserFactory
class MyModuleStoreTestCase(SharedModuleStoreTestCase):
@classmethod
def setUpClass(cls):
super(MyModuleStoreTestCase, cls).setUpClass()
cls.course = CourseFactory.create()
def setUp(self):
super(MyModuleStoreTestCase, self).setUp()
self.user = UserFactory.create()
CourseEnrollmentFactory.create(
user=self.user, course_id=self.course.id
)
Important things to note:
1. You're creating the course in setUpClass(), *not* in setUp().
2. Any Django ORM operations should still happen in setUp(). Models created
in setUpClass() will *not* be cleaned up, and will leave side-effects
that can break other, completely unrelated test cases.
In Django 1.8, we will be able to use setUpTestData() to do class level init
for Django ORM models that will get cleaned up properly.
