Add tests

[kynan]

Some simple unit tests to make sure we don't accidentally break stuff.

[mforbes]

cram might be a good tool for this. (It is based on the tool used to test mercurial.)

[kynan]

OK, will take a look. I'm a big fan of pytest.

[kynan]

Have started with a trivial Travis config that only runs flake8.

[mforbes]

I added a small modules pytest_cram.py that allows you to run cram from pytest as well as a small (dummy) test that runs mercurial. I am not finished with my hooks yet, but you should be able to simply modify this to run git tests.

@mforbes Great, do you want to pr this?

[mforbes]

Sure. Could you please remind me what I have to do to rebase my changes on yours or shall I just submit the PR as is? (I still find git somewhat confusing and am not sure of the magic incantation needed to pull in your changes and then rebase mine...)

[kynan]

Ah, yes, sure! Assuming my repo is upstream you do

git fetch upstream
git rebase upstream/master
git push --force

[mforbes]

Done. (thanks)

[kynan]

We have some simple tests now (to be extended!), hence closing.
