如何为Django测试指定一个数据库，而不是每次都建立一个数据库？ [英] How can I specify a database for Django Tests to use instead of having it build it everytime?

问题描述

我想能够使用现有的测试数据库来运行我的测试，每次我想运行测试时，Django都不会创建和删除数据库。这是可能的吗？

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 everytime I want to run the tests. Is this possible?

推荐答案

这可能是这样的：

1）定义你自己的测试运行器，看看这里查看如何。

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

2）对于您的自定义测试运行器，请查看默认测试运行器，您可以只复制代码并将代码注释到以下行： connection.creation.destroy_test_db（old_name ，详细）它负责销毁测试数据库，我认为你应该把 connection.creation.create_test_db（..）尝试除了这样的事情可能：

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）绑定 TEST_RUNNER ，将settings.py设置为测试运行器。

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

4）现在运行测试如下：./manage.py test

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