Django:单元测试抽象模型的最佳方式 [英] Django: Best way to unit-test an abstract model

问题描述

我需要为抽象的基础模型编写一些单元测试，它提供了一些其他应用程序应该使用的基本功能.有必要定义一个继承自它的模型仅用于测试目的；是否有任何优雅/简单的方法来定义该模型仅用于测试?

I need to write some unit tests for an abstract base model, that provides some basic functionality that should be used by other apps. It it would be necessary to define a model that inherits from it just for testing purposes; are there any elegant/simple ways to define that model just for testing?

我见过一些黑客"使这成为可能，但从未在 django 文档或其他类似地方看到过官方"方式.

I have seen some "hacks" that make this possible, but never seen an "official" way in the django documentation or in other similar places.

推荐答案

我自己刚刚偶然发现了这个功能:您可以从 tests.py 中的抽象模型继承并照常进行测试.当您运行manage.py tests"时，Django 不仅会创建一个测试数据库，还会验证 &同步您的测试模型.

Just stumbled across this feature myself: You can just inherit from your abstract model in tests.py and test that as usual. When you run 'manage.py tests', Django not only creates a test database, but also validates & syncs your test models.

使用当前的 Django 主干(版本 1.2)对其进行了测试.

Tested it with current Django trunk (version 1.2).
