Using chance.js inside AngularJS end to end tests

Question

I'm trying to generate some random data for my e2e tests. Seems that the only library I found was chance.js. But can't make it works. This is what I've tried so far:

describe('In the login page', function () {
  var chance = new Chance(); // ReferenceError: Chance is not defined

}

Then adding

beforeEach(function(){

        browser.executeScript(
            function() {
                return chance;
            }).then(function(_chance){
                chance = _chance; //It returns an object, but can't use any of the methods.

            });
        });

But if I try

beforeEach(function(){

        browser.executeScript(
            function() {
                return chance.email(); //Note this line here
            }).then(function(_chance){
                chance = _chance; //It returns an email

            });
        });

Thats all I have so far... any clue/idea?

Answer 1

First, install chance.js in your project:

npm install chance --save-dev

This installs chance.js as a node module in your project. Then include it in your spec and instantiate:

var chance = require('../node_modules/chance').Chance();

Then call in your spec. For example:

it('should add a new friend', function() {
    var friendName = chance.string()
    friendPage.addFriend(friendName);

    expect(friendPage.inResults(friendName)).toBeTruthy();
});

Hope that helps...
