Django 1.7.1 のユニットテストをPyDevで実行するとAppRegistryNotReadyが発生する

Eclipse + PyDev で、Django1.7.1 のユニットテストを実行すると、AppRegistryNotReady エラーとなる。

とりあえず、リクエストの結果を取りたいだけで、別段変わったことはしていない。のに。。。

# -*- encoding:utf-8 -*-
from django.conf import settings
from django.test import TestCase
from django.test.client import Client
from phraseit import *

class ViewTest(TestCase):
    def test_home(self):
        c = Client()
        req_param = {}
        res = c.get('/', req_param)
        print res.status_code
        print res

実行すると、こんなエラー。

普通に実行は可能で、ブラウザから実行結果は確認できるのだが、ユニットテストだとだめ。

ググってみると、以下の処理を差し込む必要があるようだ。

If you’re using Django in a plain Python script — rather than a management command — and you rely on theDJANGO_SETTINGS_MODULE environment variable, you must now explicitly initialize Django at the beginning of your script with:

>>> import django
>>> django.setup()
Otherwise, you will hit an AppRegistryNotReady exception.

テストケースに、上記の import django, dango.setup() を追記してみる。

# -*- encoding:utf-8 -*-
from django.conf import settings
from django.test import TestCase
from django.test.client import Client
from phraseit import *

import django
django.setup()

class ViewTest(TestCase):
    def test_home(self):
        c = Client()
        req_param = {}
        res = c.get('/', req_param)
        print res.status_code
        print res

成功。
