Question

我有角度1.5控制器的ES6类。我正在尝试使用jasmine / karma和angular-mocks编写相同的单元测试。但是，我不知道如何为$ inject注入我的依赖项（如$ filter）添加单元测试。我该如何测试，最初this.users是一个数组。另外我想知道如何测试生命周期钩子，如$ inject和$ destroy。

目前，当我运行这些测试时，我得到以下异常，我不明白。我是编写单元测试的新手。我看到它无法找到对象

作为TypeError：无法读取属性＆＃39;用户＆＃39;未定义的在对象。（测试context.js：35022：37）

这是ES6 Class

class UsersCtrl {
    constructor($filter) {
        this.i18n = $filter('i18n');
        this.users = [];
    }
//Life cycle Hooks: Initialization
$onInit() {
    this.users = [
        {name: this.i18n('USERS')}
    ];
}
//Life cycle Hooks: Destroy
  $onDestroy() {
  }
}

  UsersCtrl.$inject = ['$filter'];

 angular.module('app', []).controller('UsersCtrl',UsersCtrl);

export default UsersCtrl;

我的单元测试如下

Import UsersCtrl from './users-controller.js';

describe("given a new Users Page", () => {

var UserController;

beforeEach(() => {
    angular.mock.module('app', []);
});

describe("when initialising  has completed", () => {

    beforeEach(() => {
        inject(($rootScope, $controller, $filter) => {
            const scope = $rootScope.$new();
            const filter = $filter
            UserController = $controller("UsersCtrl", { $scope: scope, $filter: filter});
        });
    });

    it("then users array for tab content should be empty initially", () => {
        const expectedActive = [];       
        expect(UserController.users).toEqual(expectedActive);
    });
});

}）;

在angular1.5 x上下文中，ES6控制器的茉莉花单元测试失败，但有例外
