对具有出厂参数的组件控制器进行单元测试。 Angularjs和业力

Question

spec.js

'use strict';

describe('homeView', function () {

    var $componentController;
    var controller;

    // loads the module
    beforeEach(module('homeView'));

    beforeEach(inject(function ($injector) {
        $componentController = $injector.get('$componentController');
        controller = $componentController('homeView', {
            $scope: {},
            $route: {},
            EmpApi: "What should I write here???"
        });
    }));

    //beforeEach(inject(function (_$componentController_) {
    //    $componentController = _$componentController_;

    //}));


    it('test number', function () {

        expect(controller.number).toEqual(7);
    });

});

模块

angular.module('homeView', []);

组件

angular.
    module('homeView').
    component('homeView', {
        templateUrl: 'home-view/home-view.template.html',
        controller: ['$scope', '$route', 'EmpApi',
            function HomeViewController($scope, $route, EmpApi) {
                this.number = 7;

            }
        ]
    });

EmpApi是从工厂返回的对象。如何对该参数为$ scope，$ route和EmpApi的控制器进行单元测试？如果删除有关route和Empapi的所有内容，则它通过了测试。当我保留它们时，会出现此错误

TypeError: EmpApi.getInterviewees is not a function

getInterviewees是EmpApi中的一个函数，在这段测试代码中我什至没有调用它。
