Running

The makefile has two targets (start and stop) to make you run the grader in server mode and expose it to the internet. These targets use pm2 to start and stop both the grader and an ngrok server. The ngrok server should be configured with an .ngrok file; this is my ~/.ngrok file:

auth_token: your auth token
tunnels:
    grader:
        subdomain: "grader.cms.zaccaria"
        proto:
            http: 1666

After ngrok started, the server is reachable in this case at: http://grader.cms.zaccaria.ngrok.com. This is the address to use for the Edx push xqueue.

Tests

Tests are categorized in three parts:

1. Tests for the server part (via supertest); these dont really require app-armor. They just check that data the overall client-server protocol complies with xqueue specs (invoked with make test).
2. Fake tests for the code-jail environment; these test the sequencing of actions that should be done when launching an application through app-armor, even if you dont have app-armor (e.g., I am developing on a Mac). These are invoked by ./test/test.sh.
3. App-armor execution; these run some sample scripts under app-armor, by assuming you are under linux 14.04. These are invoked by ./test-local/test.sh
