我一直在跟随John Papa和Ward Bell对PluralSight进行角度测试.

当我运行我的规格时,我目前收到以下错误.

AssertionError: expected { Object ($$state) } to have a property 'length'
at Assertion.assertLength (bower_components/chai/chai.js:1331:37)
at Assertion.assert (bower_components/chai/chai.js:4121:49)
at Context.<anonymous> (scripts/home/homeController.Specs.js:48:49)

请注意,我只包含了我认为相关的代码,因此我没有用无关的信息重载这个问题.如果您需要查看更多代码,这不是问题.

我的代码如下:

homeController.js:

window.app.controller('homeController', ['$scope', 'sidebarService',
             function ($scope, sidebarService) {

    $scope.title = 'Slapdash';
    $scope.sidebar = {
        "items": sidebarService.getSidebarItems()
    };

}])

sidebarService.js:

(function () {
window.app

    .service('sidebarService',['$http', function ($http) {

    this.getSidebarItems = function () {
        $http.get("http://wwww.something.com/getSidebarItems")
            .then(function (response) {
                return response.data;
            });
       };
   }]);
}());

homeController.Specs.js:

beforeEach:

beforeEach(function () {

    bard.appModule('slapdash');

    bard.inject(this, '$controller', '$q', '$rootScope')

    var mockSidebarService …

我正在编写一个角度控制器,它对数据服务有依赖性(数据服务转到http服务器),我想模仿它的行为.

我正在使用一个名为bard js的库进行模拟,它有一个名为bard.mockService的模拟服务api .

在beforeEach语句中,我正在做:

beforeEach(function() {
    bard.appModule('app.process.creation');
    bard.inject('$controller', '$rootScope', '$q', 'processCreationDataservice');

    bard.mockService(processCreationDataservice, {
        createProcess: $q.when({}),
        _default: $q.when([])
    });

    controller = $controller('ProcessCreationController');
    $rootScope.$apply();
});

然后我的测试:

it('should call create process data service to create process', function() {
    controller.create();
    expect(processCreationDataservice.createProcess).to.have.been.calledOnce;
});

正如您在测试中看到的那样,我想声明dataservice.createProcess被调用一次.

控制器没有调用方法processCreationDataservice.createProcess,仍然测试正在通过.

(function() {
angular
    .module('app.process.creation')
    .controller('ProcessCreationController', ProcessCreationController);

ProcessCreationController.$inject = ['processCreationDataservice'];

function ProcessCreationController(processCreationDataservice) {
    var vm = this;

    vm.process = {
        name: '',
        bankId: ''
    };

    vm.create = function() {

    };
}})();

我想知道为什么这个测试正在通过,我该怎么做才能断言该方法被调用一次.

我按照这些说明操作:https: //github.com/wardbell/bardjs#mockService
