Jasmine test angular-translate calls

controller.spec.js

/*
silly way to ensure $translate service has been called with correct key and arguments
*/
var $translate;

beforeEach(inject(function (_$translate_) {
  $translate = function() {
      $translate.spy.apply(this, arguments);
  };
  $translate.spy = function() {};
  spyOn($translate, 'spy').andCallFake(function() {
     // dummy
  });
});

it('should call translate service with correct parameters', function() {
  // check we call $translate('translation-key-to-check', {username: 'Bill Cosby'});
  expect($translate.spy).toHaveBeenCalledWith('translation-key-to-check', {username: 'Bill Cosby'});
});
