The VM IP is currently set in Vagrantfile; head to http://192.168.1.33 and see the glory for yourself. To prevent people stealing your bananas, you can also use https://192.168.1.33, although you'll get warnings as the certificate is self-signed.
There are limited automated tests, which can be run with the following:
pip install tests/requirements.txt
chmod +x test.sh
./test.sh
