Not able to access the django test database

Question

I try to do some testing in django on the deployment server. I am trying to run a django.test.TestCase test - the test doesn't do anything yet. I have given the test database a name:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'mydatabase',
        'USER': 'User1',
        'PASSWORD': 'XXXXXX',
        'HOST': '',
        'PORT': '',
        'TEST_NAME': 'test_mydatabase',
    }
}

However, if I run the tests I always get an exception. The test seems to try to access a database called "postgres".

Creating test database for alias 'default'...

How can I resolve this? Any clues would be appreciated.

Django需要具有创建数据库的权限，否则测试将无法进行。
