Add tests

[zachkont]

This is mostly addressed to people new in python and/or github

Every good project should include some unit testing. Here are some useful links about it:

• Test-Driven Development in Python
• More Test-Driven Development in Python
• Unit testing framework

Please submit your tests at the tests branch, and keep it at 1 commit per test.
Comments will be appreciated.

Keen on giving a hand where I can. I've a little experience in Python but not in unit testing.

What kind of tests have you got in mind?

I would also be happy to help up and brush up on my unit testing knowledge! I'm also quite new but this sounds manageable and @questionmarcus and me could write different tests? Happy to discuss here.

At the expense of this being a silly newbie question: Once we have everything installed, set up, tokens set up, own bot created etc and the telegram bot AnnouncerDude set up - in order to write the tests, what are we actually supposed to run? (I've put the tokens into the settings.py and changed the name as well.)

Have you decided what you'd like to use for tests? Unittest / pytest / something else?

@mvi-x I was thinking unit tests to begin with but pytest looks interesting. The end goal would be to have a full start-to-end test scenario since the functionality is not that extensive, including testing of commands and of the automated updates (probably by deleting the latest entry in the json files).

Generally, the point is to fully automate pull requests, hopefully.

@questionmarcus & @alaskaa I guess you could start by writing some unit tests for the updater.py functions. As simple as they may be, it would be a solid start.

@alaskaa the links that I have included are a good start for your question (no question is silly btw) so I suggest giving those a look. Also, pytest that @mvi-x mentioned looks nice, I have never used it though. I probably should have set up a base for you guys, sorry. I'll try doing that next weekend if none has pushed anything yet
