This simple library allows to create fake models in your test without migrations, test apps and test tables in your base. All tables that you need will created/removed during the test.
Install
Install django-fake-model:
pip install django-fake-model
Quickstart
Just create a model in any file (Ex: in your test) and add decorator @YourModel.fake_me to test method or test class.
from django_fake_model import models as f
from django.db import models
from django.test import TestCase, TransactionTestCase
class MyFakeModel(f.FakeModel):
name = models.CharField(max_length=100)
@MyFakeModel.fake_me
class MyFakeModelTests(TestCase):
def test_create_model(self):
MyFakeModel.objects.create(name='123')
model = MyFakeModel.objects.get(name='123')
self.assertEqual(model.name, '123')
class MyFakeModelFunctionTest(TestCase):
@MyFakeModel.fake_me
def test_create_model(self):
MyFakeModel.objects.create(name='123')
model = MyFakeModel.objects.get(name='123')
self.assertEqual(model.name, '123')
class RelatedModel(f.FakeModel):
text = models.CharField(max_length=400)
class NyModel(f.FakeModel):
text = models.CharField(max_length=400)
related_model = models.ForeignKey(RelatedModel)
@NyModel.fake_me
@RelatedModel.fake_me
class TestRelatedModelsClassDecorator(TransactionTestCase):
def test_create_models(self):
related_model = RelatedModel()
related_model.text = 'qwerty'
related_model.save()
my_model = NyModel()
my_model.test = 'qwerty'
my_model.related_model = related_model
my_model.save()
self.assertIsNotNone(my_model)
self.assertIsNotNone(related_model)Development:
To develop on this locally with Docker, install the Docker Engine and Docker Compose. Then you can build the Docker image and run the tests on all tox activities(this also uses a shared pip cache to reduce download times):
docker-compose up -d pg mysql docker-compose run --rm test
If you wanna run just one Tox activity you can specify that as well:
docker-compose run --rm test tox -e py35-dj19-mysql-unittest
If you add any dependencies or change the tox configuration, you have to rebuild the image:
docker-compose build
It will share this folder with the Docker containers, so that
