Question

我正在尝试将控制器测试为vm，但得到错误

主要模块：

(function() {
    'use strict';

    angular.module('ds', [
            'ionic',
            'ui.router',
            'ds.controllers',
            'ds.services',
            'ds.filters',
            'underscore',
            'ionicLazyLoad',
            'ngCordova',
            'ngIOS9UIWebViewPatch'
        ])
})();

控制器代码如下：

(function() {
    'use strict';

    angular
        .module('ds')
        .controller('LoginCtrl', LoginCtrl);

    LoginCtrl.$inject = ["$scope", "$rootScope"];

    function LoginCtrl($scope, $rootScope) {

        var vm = this;

        vm.model = { name: "controllerAs vm test" };

    }
})();

我的茉莉花测试：

   'use strict';

    describe('LoginCtrl', function() {
        var LoginCtrl;
        beforeEach(module('ds'));

        beforeEach(function() {
            inject(function($injector) {
                LoginCtrl = $injector.get('$controller')('LoginCtrl', {});
            });
        });

    it('LoginCtrl should be defined and LoginCtrl.name is equal to controllerAs vm test', function() {
        expect(LoginCtrl).toBeDefined();
        expect(LoginCtrl.name).toEqual("controllerAs vm test");
    });
});

并收到此错误：

这部分我的业力配置文件：

    '../lib/ionic/js/ionic.bundle.js',
    '../lib/angular-mocks/angular-mocks.js',
    '../lib/jquery/dist/jquery.js',

    '../js/*.js',
    '../js/**/*.js',
    '../modules/**/*.js',
    'unit-tests/*.js',
],

有人对如何解决这个问题提出任何建议，或者有关于如何使用John Papa角度风格指南和单元测试的指南？

谢谢！

Answer 1

我们使用这种构造进行测试（虽然我们使用ES6与ES5）：

let vm;
inject((_$controller_, _$rootScope_) => {
  vm = _$controller_(SomeControllerImport,
    { $scope: _$rootscope.$new() });
});

然后在您的测试中，您可以像在普通控制器代码中一样直接引用vm：

expect(vm.foo).toHaveBeenCalled();

等等。

使用jasmine John Papa控制器作为vm进行测试时出错
