Django的单元测试与传统的数据库连接

我有一个从传统数据库（只读连接）中提取数据到自己的数据库中的Django项目，当我运行集成测试，它试图从test_account遗留连接读取。Django的单元测试与传统的数据库连接

(1049, "Unknown database 'test_account'")

有没有办法告诉Django离开遗留连接单独从测试数据库读取？

如果您想查看如何创建单独的集成测试框架，我实际上已经编写了一些内容，可让您在djenga（pypi上提供）中创建集成测试。

下面是测试运行我使用Django的单元测试框架时使用：

from django.test.runner import DiscoverRunner 
from django.apps import apps 
import sys 

class UnManagedModelTestRunner(DiscoverRunner): 
    """ 
    Test runner that uses a legacy database connection for the duration of the test run. 
    Many thanks to the Caktus Group: https://www.caktusgroup.com/blog/2013/10/02/skipping-test-db-creation/ 
    """ 
    def __init__(self, *args, **kwargs): 
     super(UnManagedModelTestRunner, self).__init__(*args, **kwargs) 
     self.unmanaged_models = None 
     self.test_connection = None 
     self.live_connection = None 
     self.old_names = None 

    def setup_databases(self, **kwargs): 
     # override keepdb so that we don't accidentally overwrite our existing legacy database 
     self.keepdb = True 
     # set the Test DB name to the current DB name, which makes this more of an 
     # integration test, but HEY, at least it's a start 
     DATABASES['legacy']['TEST'] = { 'NAME': DATABASES['legacy']['NAME'] } 
     result = super(UnManagedModelTestRunner, self).setup_databases(**kwargs) 

     return result 

# Set Django's test runner to the custom class defined above 
TEST_RUNNER = 'config.settings.test_settings.UnManagedModelTestRunner' 
TEST_NON_SERIALIZED_APPS = [ 'legacy_app' ]

from django.test import TestCase, override_settings 

@override_settings(LOGIN_URL='/other/login/') 
class LoginTestCase(TestCase): 

    def test_login(self): 
     response = self.client.get('/sekrit/') 
     self.assertRedirects(response, '/other/login/?next=/sekrit/')

你应该在理论上可以在这里使用的替代设置，并切换到一个DIF
