pytest test cases

[dabrown645]

I have some pytest test cases developed mostly using the 'demo' apikey are you interested?
there are quite a few cases where the demo line they provide don't work so those tests may not be very accurate.

When I started out I remember reading the free account was 500/mo (at least that is my recollection) which was going to be enough for my very limited usage. However, I checked today and the free limit is now 250 max so doesn't look like I am going to be working with this much.

Looks like you had some thought of supporting financialmanagementprep with the inclusion of it's url in settings.py I might try looking into that.

Hope these test cases are useful.
