Django 1.7 mongo无法运行测试

Question

我用的是两个数据库。我的基础是postgres数据库，secound是mongodb。我的项目运行良好，但当我运行测试时： 我的配置-当我注释default\u mongo时，测试运行正常：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        'TEST_NAME': 'my_test_sql',
        'TEST_USER': 'test_sql_user',
        'TEST_PASSWORD': 'password'
    },
    'default_mongo': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'bid',
        'USER': '',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '27017',
        'SUPPORTS_TRANSACTIONS': False,
        'TEST_NAME': 'my_test_mongodb',
        'TEST_USER': 'test_mongo_user',
        'TEST_PASSWORD': 'password'
    },
}

/管理.py测试

$ ./manage.py test
