在主Django数据库上运行Unittest [英] Run Unittest On Main Django Database

问题描述

我正在寻找一种在django测试期间运行完整芹菜设置的方法，在这个其他SO问题

I'm looking for a way to run a full celery setup during django tests, asked in this other SO question

在考虑之后，我想我可以安排运行单元测试它是更多的一个集成测试），其中我运行测试脚本对主Django（开发）数据库。有没有办法编写单元测试，使用Nose运行它们，并对主数据库执行？我想象这是一个关于django设置的Nose（或任何其他框架）的问题。

After thinking about it, I think I could settle for running a unittest (it's more of an integration test) in which I run the test script against the main Django (development) database. Is there a way to write unittests, run them with Nose and do so against the main database? I imagine it would be a matter of telling Nose (or whatever other framework) about the django settings.

我看过 django-nose ，但无法找到一种方法来告诉它使用主数据库，而不是测试。

I've looked at django-nose but wasn't able to find a way to tell it to use the main DB and not a test one.

推荐答案

我不知道有关鼻子，但是这里是如何使用django（1.6）单元测试来反对现有的数据库。

I don't know about nose, but here is how to run against and existing db with django (1.6) unit tests.

from django.test.runner import DiscoverRunner
from django.db import transaction

class ExistingDBTestRunner(DiscoverRunner):

    def run_tests(self, test_labels, extra_tests=None, **kwargs):
        self.setup_test_environment()
        suite = self.build_suite(test_labels, extra_tests)
        #old_config = self.setup_databases()
        result = self.run_suite(suite)
        #self.teardown_databases(old_config)
        self.teardown_test_environment()
        return self.suite_result(suite, result)

然后在settings.py

Then in settings.py

if 'test' in sys.argv:
     TEST_RUNNER = '<?>.ExistingDBTestRunner'
     # alternative db settings?

在旧版本的django中会有所不同。此外，您可能需要在您的测试用例中覆盖_fixture_setup和_fixture_teard才能传递。

It will be a little different in older versions of django. Also, you may need to override _fixture_setup and _fixture_teardown in your test cases to pass.

上述代码将连接到预先存在的数据库，但由于每个测试都包含在一个事务中其他连接（如芹菜工作者）将无法使用更改。禁用交易的最简单的方法是从 unittest.TestCase 而不是 django.test.TestCase 。

The above code will connect to a preexisting database but since each test is wrapped in a transaction the changes won't be available to other connections (like the celery worker). The easiest way to disable transactions is to subclass from unittest.TestCase instead of django.test.TestCase.
