Django 1.8 compatibility

[PabloCastellano]

This code won't work in Django 1.8 since it removes django.test.simple.

From https://docs.djangoproject.com/en/1.8/releases/1.6/#discovery-of-tests-in-any-test-module:

Discovery of tests in any test module¶

Django 1.6 ships with a new test runner that allows more flexibility in the location of tests. The previous runner (django.test.simple.DjangoTestSuiteRunner) found tests only in the models.py and tests.py modules of a Python package in INSTALLED_APPS.

The new runner (django.test.runner.DiscoverRunner) uses the test discovery features built into unittest2 (the version of unittest in the Python 2.7+ standard library, and bundled with Django). With test discovery, tests can be located in any module whose name matches the pattern test*.py.

As @PabloCastellano commented is deprecated on version 1.8 https://docs.djangoproject.com/en/dev/internals/deprecation/#deprecation-removed-in-1-8.

Also, pymongo uses now MongoClient instead of Connection, and you need to disconnect from default database

A quick fix may be:

from django.test.runner import DiscoverRunner
from django.test import TransactionTestCase
from django.conf import settings
from mongoengine import connect, disconnect
from pymongo import MongoClient

class TestRunner(DiscoverRunner):
    """
    Custom test runner for mongoengine
    """
    def setup_databases(self, **kwargs):
        db_name = settings.TEST_DBNAME # test db defined on settings
        disconnect() # disconnect from default db
        connect(db_name)
        print 'Connecting to test database: ' + db_name
        return db_name

    def teardown_databases(self, db_name, **kwargs):
        if not self.keepdb:
            conn = MongoClient()
            conn.drop_database(db_name)
            print 'Dropping test database: ' + db_name


class TestCase(TransactionTestCase):
    def _fixture_setup(self):
        pass
