'use strict';

describe('dashboardService', function () {
  var dashboardService;

  beforeEach(module('abc'));

  beforeEach(inject(function (_dashboard_) {
    dashboardService = _dashboard_;
  }));
   it('getAllMasterJobsNames method should defined and should return promise', function () {
    expect(dashboard.getAllMasterJobsNames).toBeTruthy();
    expect(dashboard.getAllMasterJobsNames.name).toEqual('getAllMasterJobsNames');
    expect(dashboard.getAllMasterJobsNames(0)).toEqual({$$state:{status:0}});

  });
});
