How do you return from a Meteor.methods stub in Cucumber

I have just begun using Cucumber (xolvio:cucumber@0.20.2_1) with Meteor to test my project, and I am having difficulty returning a value from a Meteor.methods stub I created within a step definition.

register-user.js

this.When(/^he clicks the verification link in his email$/, function () {
        console.log(this.server.call('_getUser'));
});

registration.js

Meteor.methods({
    _getUser: function() {
        return Meteor.users.findOne({'emails.address': 'anyemail@email.com'});
});

The log outputs a huge object that looks like the state of the system. I noticed elsewhere that someone suggested

this.server.call('aMethod').then(function(response) {

    // you can use the response here

});

But when I do this in my project, cucumber logs Object [object Object] has no method 'then'.

I also tried Meteor.users.findOne({'emails.address': anemail@email.com}); within the step definition, but I am receiving the error Meteor is not defined

Any help or guidance would be greatly appreciated.

EDIT I realized that when I was logging a huge object, it was because the Meteor method _getUser wasn't returning anything. I then tried Meteor.users.find({}).fetch() and it returned an empty array, even though my meteor-cucumber collection had my user there, which is another issue I'm experiencing.

You don't need to use this or then, the latest version of Chimp is synchronous, so you just do this:

var user = server.call('_getUser')

Just be sure to have registration.js as part of your Meteor app and not part of the test codebase.
