how can i use api-test.box.com with BOX SDK for Python

I want to test by changing the connection destination of the API.
I want to use only api-test.box.com.

Therefore,
I changed api.box.com in config.py to api-test.box.com.

I made the following connections:

>>> from boxsdk import DevelopmentClient
>>> client = DevelopmentClient()
Enter developer token: <ENTER DEVELOPER TOKEN HERE>
>>> user = client.user().get()

I received the following response.

GET https://api-test.box.com/2.0/users/me {'headers': {'Authorization': '---wXyZ',
            'User-Agent': 'box-python-sdk-2.0.0',
            'X-Box-UA': ...


After this, I think that api.box.com is no longer used.

But I don't know if it's correct.

Please let me know.
