Comment (by Ashley Waite): This was a particularly annoying issue to me, which I resolved by creating a new TestRunner that did the work for me. I think including something like this for easy use would effectively resolve this. {{{ from importlib.util import find_spec import unittest from django.apps import apps from django.conf import settings from django.test.runner import DiscoverRunner class TestLoader(unittest.TestLoader): """ Loader that reports all successful loads to a runner """ def __init__(self, *args, runner, **kwargs): self.runner = runner super().__init__(*args, **kwargs) def loadTestsFromModule(self, module, pattern=None): suite = super().loadTestsFromModule(module, pattern) if suite.countTestCases(): self.runner.register_test_module(module) return suite class RunnerWithTestModels(DiscoverRunner): """ Test Runner that will add any test packages with a 'models' module to INSTALLED_APPS. Allows test only models to be defined within any package that contains tests. All test models should be set with app_label = 'tests' """ def __init__(self, *args, **kwargs): self.test_packages = set() self.test_loader = TestLoader(runner=self) super().__init__(*args, **kwargs) def register_test_module(self, module): self.test_packages.add(module.__package__) def setup_databases(self, **kwargs): # Look for test models test_apps = set() for package in self.test_packages: if find_spec('.models', package): test_apps.add(package) # Add test apps with models to INSTALLED_APPS that aren't already there new_installed = settings.INSTALLED_APPS + tuple(ta for ta in test_apps if ta not in settings.INSTALLED_APPS) apps.set_installed_apps(new_installed) return super().setup_databases(**kwargs) }}} -- Ticket URL: <https://code.djangoproject.com/ticket/7835#comment:42> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
