Tests boilerplate

[davidedelvento]

Getting started has been trickier than I thought, because so many things had changed since last time I did something similar.

Basically this PR is for "nothing", just boilerplate to make two of your own tests run automatically at every push (and renamed the others to "try" otherwise it would fail). As soon as I have time (only weekends, sorry) I'll try to do more, but meanwhile you have something to get started, if you wish.

Note that you'll have to change the location of the badge in the README.md, since as far as I understand it needs to have an absolute location, not a relative one, so if you leave it as it is it will point to my fork, sigh.
