Document how to set the language for the test client

[Claude Paroz]

I suggest to add a note in the documentation about how to set the language for the test client.

Without the LocaleMiddleware, it's possible to set it with the activate/deactivate functions from django.utils.translation.

When LocaleMiddleware is activated, another method has to be used, otherwise the settings.LANGUAGE_CODE is always used. I've been able to set the language by passing HTTP_ACCEPT_LANGUAGE='de' to the get/post method, or by loading a cookie (client.cookies.load({settings.LANGUAGE_COOKIE_NAME:'de'})).

BTW, the activate/deactivate functions from django.utils.translation aren't documented either.

Change UI/UX from NULL to False.

Change Easy pickings from NULL to False.

Looks like this could go in the test client documentation at docs/topics/testing/tools.txt.

I'm interested in contributing to Django and have been advised to start with some of the 'easy pickings' tasks, so I'll try picking up this issue to get started.

I've made the proposed changes to the testing tools topic documentation and pushed it to the branch ​https://github.com/mscott250/django/tree/ticket_15143 . I think the text looks suitable and I've included examples of the different ways to set the language.

I've created a pull request for the branch as the contributing docs say to do, it's available here ​https://github.com/django/django/pull/7233 . Please let me know if you think the text can be improved in any way or if there is anything else I need to do for this contribution.

Cheers,
Michael

Thanks for the feedback Simon, I've addressed all the items you mentioned and after fighting with Git a little bit I've created another pull request here ​https://github.com/django/django/pull/7238 .

Please let me know if there's any further improvements I can make to it or if there's anything else to do for this.
