How to create table during Django tests with managed = False

Question

I have a model with managed = False.

class SampleModel(models.Model):
    apple = models.CharField(max_length=30)
    orange = models.CharField(max_length=3

Just to add :django.db.models.loading.get_models will be removed in Django 1.9 (see https://github.com/BertrandBordage/django-cachalot/issues/33).

Below is an updated one for Django 1.10:

class UnManagedModelTestRunner(DiscoverRunner):
    '''
    Test runner that automatically makes all unmanaged models in your Django
    project managed for the duration of the test run.
    Many thanks to the Caktus Group 
    '''

    def setup_test_environment(self, *args, **kwargs):
        from django.apps  import apps
        self.unmanaged_models = [m for m in apps.get_models() if not m._meta.managed]
        for m in self.unmanaged_models:
            m._meta.managed = True
        super(UnManagedModelTestRunner, self).setup_test_environment(*args, **kwargs)

    def teardown_test_environment(self, *args, **kwargs):
        super(UnManagedModelTestRunner, self).teardown_test_environment(*args, **kwargs)
        # reset unmanaged models
        for m in self.unmanaged_models:
            m._meta.managed = False 

Note you also need to take care migrations(see Testing django application with several legacy databases)

MIGRATION_MODULES = {
    'news': 'news.test_migrations',
    'economist': 'economist.test_migrations'
}
