Custom test client

[singingwolfboy]

Having a custom test client makes it easier to write automated tests using Flask-Login.

This makes sense to me! 👍

Great! Do you have any feedback on the functionality or the documentation? I know that Flask-Login sets more values in the session cookie than user_id and _fresh, but those two were the easiest to handle, so I only included those. If you have a suggestion for how to handle the other values, I'd love to hear it! Alternatively, we can start with minimal functionality for now, and add more over time.

And are the docs clear? I always want to verify that my documentation is understandable to someone who didn't write the code. 😄

Coverage remained the same at 100.0% when pulling 28ea1b0 on singingwolfboy:custom-test-client into b07c159 on maxcountryman:master.

This way is more explicit:
def __init__(self, user=None, fresh_login=True, *args, **kwargs):

I know the FlaskClient docs show using kwargs.pop so either is fine.

Great, thanks for merging! Any idea when there will be a new release of Flask-Login, so people can use this feature?

[alanhamlett]

@maxcountryman does the releases. Thanks for adding this, it will be very helpful when testing.

Cool. Let's move this discussion over to issue #425.
