javascript - 像 Jasmine 一样测试 Angular Controller

Question

我是 Jasmine/Angular 测试的新手，正在尝试测试我拥有的 Controller 。 Controller 代码如下

(function () {
'use strict';

angular
    .module('App')
    .controller('ActionEventsCtrl', ActionEventsCtrl);

ActionEventsCtrl.$inject = ['$log', 'ActionEvents'];

function ActionEventsCtrl($log, ActionEvents) {
    /* jshint validthis:true */
    var vm = this;
    //getActionEvents();

    vm.ActionEvents = [
                { "description": "Second Notification", "type": 4, "dateRaised": "2014-10-17T00:00:00", "hasNotified": true, "status": 0, "user": null, "id": 6 },
                { "description": "Third Notification", "type": 2, "dateRaised": "2014-10-18T00:00:00", "hasNotified": true, "status": 1, "user": null, "id": 7 }
    ];

    vm.init = getActionEvents();

    function getActionEvents() {
        var userId = 1;
        ActionEvents.get(userId).then(
            function onSuccess(response) {
                vm.ActionEvents = response.data;
        },
        function onFailure(response) {

            $log.error("Loading of ActionEvents failed with response: ", response);
        });

    }
}

})();

我写了一个测试如下

describe("App", function () {

describe("ActionEvents Controller", function () {

    //basic mock lookup service which returns empty arrays
    var mockActionEventsService = {
        get: function (userId) {
            return [
                { "description": "Second Notification", "type": 4, "dateRaised": "2014-10-17T00:00:00", "hasNotified": true, "status": 0, "user": null, "id": 6 },
                { "description": "Third Notification", "type": 2, "dateRaised": "2014-10-18T00:00:00", "hasNotified": true, "status": 1, "user": null, "id": 7 }
            ];
        },
    };


    var scope;
    var log;
    var controller;

    beforeEach(module('TracerApp'));

    beforeEach(inject(function ($rootScope, $controller) {
        scope = $rootScope.$new();
        log = null;
        controller = $controller('ActionEventsCtrl as actionEventVM', { $log: log, ActionEvents: mockActionEventsService });
    }));


    it('should have data', function () {
        expect(scope.actionEventVM.ActionEvents).toJson();

    });

});

});

但是我得到了一个错误

Answer 1

我收到错误消息是因为我注入(inject)的 log 对象没有 error 函数。通过在日志中使用一个带有一个参数的虚拟方法来修复它。
