This is a subclass of unittest.TestCase to help manage your unit tests in Flask projects.
It sets up the application and client and exposes the request context so you can do app-specific things outside of your views.
import unittest class TestCase(unittest.TestCase): def create_app(self): """ Create your Flask app here, with any configuration you need """ raise NotImplementedError def __call__(self, result=None): """ Does the required setup, doing it here means you don't have to call super.setUp in subclasses. """ self._pre_setup() super(TestCase, self).__call__(result) self._post_tearDown() def _pre_setup(self): self.app = self.create_app() self.client = self.app.test_client() # now you can use flask thread locals self._ctx = self.app.test_request_context() self._ctx.push() def _post_tearDown(self): self._ctx.pop()
A further step would be to add convenience methods to this TestCase - for example assertRedirects or assert404:
def assert404(self, response): """ Checks if a HTTP 404 returned e.g. resp = self.client.get("/") self.assert404(resp) """ self.assertTrue(response.status_code == 404)
If you need to handle fixtures with SQLAlchemy or another ORM/backend then the Fixture package may be of use:
