DSL Extend to manipulate Cookies on e2e tests from AngularJs

angular.scenario.dsl.cookies.js

'use strict';

angular.scenario.dsl('cookies', function() {
  var chain = {};

  chain.set = function(name,value) {
    return this.addFutureAction('set cookie', function($window, $document, done) {
      var injector = $window.angular.element($window.document.body).inheritedData('$injector');
      var cookies = injector.get('$cookies');
      var root = injector.get('$rootScope');
      cookies[name] = value;
      root.$apply();
      done();
    });
  };

  chain.remove = function(name) {
    return this.addFutureAction('remove cookie', function($window, $document, done) {
      var injector = $window.angular.element($window.document.body).inheritedData('$injector');
      var cookies = injector.get('$cookies');
      var root = injector.get('$rootScope');
      delete cookies[name];
      root.$apply();
      done();
    });
  };

  chain.clear = function() {
    return this.addFutureAction('clear cookies', function($window, $document, done) {
      var injector = $window.angular.element($window.document.body).inheritedData('$injector');
      var cookies = injector.get('$cookies');
      var root = injector.get('$rootScope');
      for (var name in cookies) {
        delete cookies[name];
      }
      root.$apply();
      done();
    });
  };

  return function() {
    return chain;
  }
});

To use

1 - Include dsl files into karma-e2e.conf.js, ex:

files: [
  'test/dsls/**/*.js',
  'test/e2e/**/*.js'
],

2 - Use in tests (similar to methods browser(), input(), select(), etc), ex:

beforeEach(function() {
  cookies().set('id','2');
  cookies().set('person','0');
  cookies().set('login','e2e');
  cookies().set('name','E2E Tester');
  cookies().set('token','fAkEtOkEn');
  browser().reload();
});

afterEach(function() {
  cookies().clear();
});
