在Django 1.8上运行django-celery测试

Question

最终,我想让测试通过Django 1.9.django-celery目前适用于Django <1.9.因此,第一步是确保库测试在我的机器上通过Django 1.8传递.

我在测试项目中克隆了https://github.com/celery/django-celery并安装了这些要求.对于Django 1.7,测试正在通过.对于Django 1.8我应该多次得到相同的错误,而它应该工作...

请参阅https://github.com/celery/django-celery/blob/master/tox.ini包括Django 1.8:

...
1.8: Django>=1.8.0,<1.9.0

---

对于Django 1.7:

pip install Django==1.7
./django-celery/tests/manage.py test djcelery.tests
...
Ran 64 tests in 0.319s
OK

对于Django 1.8:

pip install Django==1.8
./django-celery/tests/manage.py test djcelery.tests

...
