BUG: stdout is bytes on python3

Where should I add a test?

[tobami]

There are no tests currently for the mercurial module. It'd be awesome to add at least one for the happy path, but it is not a must for this PR if you don't have the time.

stdout = str(stdout).rstrip('\n') looks clearer to me.

how do I run the tests? python -mpytest codespeed/tests doesn't work out of the box for me, some django setup is missing

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, \
but settings are not configured. You must either define the environment variable \
DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings

It's not configured to run with pytest, you can run tests the standard django way:
python manage.py test

I need to get used to django unit tests. For instance, I am used to the testing framework supplying a tmp_dir so that I could set up a hg/git repo, but spent quite a while searching for the recommended way to do this in django so that the directory is erased when tests finish. Any hints?

OTOH, it seems like a lot of work to set up testing for a small fix...
