如何为 Django 测试指定要使用的数据库，而不是每次都构建它? [英] How can I specify a database for Django Tests to use instead of having it build it every time?

问题描述

我希望能够使用现有的测试数据库来运行我的测试，而不是每次我想运行测试时都让 Django 创建和删除数据库.这可能吗?

I want to be able to use an existing test database to run my tests against and not have Django create and delete a database every time I want to run the tests. Is this possible?

推荐答案

有可能，这里有一个方法:

It's possible, here is a way :

1) 定义您自己的测试运行程序外观 此处 了解操作方法.

1) Define your own test runner look here to see how.

2) 对于您的自定义测试运行程序，请查看 默认测试运行器，你可以复制并粘贴代码，然后注释这一行:connection.creation.destroy_test_db(old_name,verbosity)，它负责销毁测试数据库，我认为您应该尝试使用 connection.creation.create_test_db(..) 行，除非可能是这样的:

2) For your custom test runner look in the default test runner, you can just copy and past the code and just comment this line : connection.creation.destroy_test_db(old_name, verbosity) which is responsible for destroying the test database, and i think you should put the connection.creation.create_test_db(..) line in a try except something like this maybe:

try:
    # Create the database the first time.
    connection.creation.create_test_db(verbosity, autoclobber=not interactive) 
except ..: # Look at the error that this will raise when create a database that already exist
    # Test database already created.
    pass 

3) 在 setting.py 中绑定 TEST_RUNNER给您的测试运行器.

3) Bound TEST_RUNNER in setting.py to your test runner.

4) 现在像这样运行你的测试:./manage.py test

4) Now run your test like this: ./manage.py test
