[Django]-LiveServerTestCase – settings.Database is improperly configured

The problem is that you are creating the user in the class definition. This runs when the test class is loaded, before the database has been created.

class ExampleTest(LiveServerTestCase):
    user = User.objects.create_superuser('Testuser','test@user.com','1234')
    user.save()  # This save isn't required -- it has been saved already

You can fix the problem by moving the user creation into an individual test. Then the user will be created when the test method runs, after the database has been created.

class ExampleTest(LiveServerTestCase):
    def test_user(self):
        self.user = User.objects.create_superuser('Testuser','test@user.com','1234')
        ...

Django 1.8 has a setUpTestData method where you can set up initial data once for the entire test case. This is quicker, and less repetitive.

class ExampleTest(LiveServerTestCase):
    @classmethod
    def setUpTestData(cls):
        # Set up data for the whole TestCase
        self.user = User.objects.create_superuser('Testuser','test@user.com','1234')

    def test_user(self):
        # access the user with self.user
        ...

In earlier versions of Django which don’t have setUpTestData, you can create the user in the setUp method.

class ExampleTest(LiveServerTestCase):
    def setUp(self):
        self.user = User.objects.create_superuser('Testuser','test@user.com','1234')

You need to set up the database in your DATABASES settings.

Django sets up a test database corresponding to every database that is
defined in the DATABASES definition in your settings file.

By default the test databases get their names by prepending test_ to
the value of the NAME settings for the databases defined in DATABASES.

If you want to use a different database name, specify NAME in the TEST dictionary for any given database in DATABASES.

An example test database configuration:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'USER': 'mydatabaseuser',
        'NAME': 'mydatabase',
        'TEST': { # test database settings
            'NAME': 'mytestdatabase', # test database name
        },
    },
}
