Forcing sails to use memory adapter during tests

test-boostrap.js

// Occassionally one needs to manually force sails to use the built-in memory adapter as a session store
// - for instance when running tests and a mysql-adapter is configured for production, we may need to 
// override session adapter settings for tests only. Turns out to be pretty simple:

Sails.lift({
  session: {
    adapter: 'memory',
    config: null
  }
});
