Is there a cleanup hook that can be used to log out of the web service being tested?

Greetings,

I'd like to run scenarios against a web app that requires login before the test can commence.
No worries, the onReady.js hooks deals with this.

The problem is that the web app keeps records of user sessions (combo of userId + session id) and only allows max 10 sessions per user. After that it's not possible to log on => not possible to run tests.
So I need to log out when tests are done.

A clean solution would be to log out in a cleanup function, but there doesn't seem to be any such hooks... or?

I thought about driving Backstop from a Node.js app, but I don't think the browser instance created by Backstop exists after the test initiated in the Node.js app is complete.

Ideas/suggestions?

Thanks!

Start by reading the onReady.js hook and the lifecycle that creates and disposes the browser instance. Determine whether a cleanup hook can run after scenarios complete and whether it can access that instance. Done means the supported lifecycle and cleanup behavior are defined, with the issue's logout use case addressed or clearly documented.
