note to self: node, nvm...

Note to self, when I'm running functional tests (for our Angular 1.X app suite) and see an error like
const builder = require('./builder');
^^^^^
SyntaxError: Use of const in strict mode.

I'm probably on the wrong node version. "nvm" is what controls that, and hopefully by using "nvm alias default X.X.X" I shouldn't see this again.

(bonus... looking into how to test validators that reject or resolve the defereds from a $q defer()

promise = creativeCreateService.validators.impressionTracker3('http://foobar.com');
expect(this.unwrapPromise(promise)).toBeTruthy();

promise = creativeCreateService.validators.impressionTracker3('https://foobar.com');
expect(this.unwrapPromise(promise)).toBeTruthy();

promise = creativeCreateService.validators.impressionTracker3(_.repeat('A',20));
expect(this.unwrapPromiseRejection(promise)).toBe('Impression tracker must start with http:// or https:// if provided');

the code that supports it is:

    self.unwrapPromise = function unwrapPromise(promise) {

        var value;

        promise.then(function (result) {

            value = result;

        });

        self.$digest();

        return value;

    };

    self.unwrapPromiseRejection = function unwrapPromiseRejection(promise) {

        var value;

        promise.catch(function (error) {

            value = error;

        });

        self.$digest();

        return value;

    };
