Angular 和 Jasmine - $scope 函数未定义
Angular and Jasmine - $scope function is undefined
我有一个控制器
var videoApp = angular.module('videoApp', ['videoAppFilters', 'ui.unique', 'angularUtils.directives.dirPagination']);
videoApp.controller('VideoCtrl', function ($scope, $http, $filter, cacheLoader, $rootScope) {
$scope.setPageSize = function (pageSize) {
$scope.pageSize = pageSize;
return $scope.pageSize;
};
$scope.addFavorite = function (data, key) {
localStorage.setItem(key, data);
$scope.videos = $filter('articleFilter')(data, $scope.allData);
return alert(key + " "+ data + " was added to your favorite list.");
};
$scope.addSelectedClass = function (event) {
if($(event.target).hasClass("selected") == true)
{
$(event.target).removeClass("selected");
} else {
$(".selected").removeClass("selected");
$(event.target).addClass("selected");
}
};
$scope.filterArticles = function (category) {
$scope.videos = $filter('articleFilter')(category, $scope.allData);
};
$scope.pageSize = 12;
cacheLoader.load('http://academy.tutoky.com/api/json.php', true, function () {
$scope.allData = $rootScope.allData;
$scope.videos = $rootScope.videos;
if(localStorage.getItem('category')) {
$scope.videos = $filter('articleFilter')(localStorage.getItem('category'), $scope.allData);
} else {
$scope.videos = data;
}
});
});
还有一个测试
describe('Check if VideoListCtrl', function() {
beforeEach(module('videoApp'));
beforeEach(inject(function (_$controller_) {
$controller = _$controller_;
}));
beforeEach(inject(function ($rootScope) {
$scope = {};
controller = $controller('VideoCtrl', { $scope: $scope });
}));
it('exists', function() {
expect(controller).not.toBeNull();
});
it('set page size', function () {
expect($scope.setPageSize(12)).toEqual(12);
});
});
我想测试控制器方法是否正常工作,但 jasmine 会在第二次测试时返回错误:
TypeError: undefined is not a function
导致问题的是 $scope.setPageSize(12)。我正在关注 angular 文档上的教程,他们正在使用范围内的方法,但在我的情况下不起作用。有人知道为什么吗?
我想你应该注意到在茉莉花中,'it' 'describe' 是函数。
因此,当您需要在 $scope 中测试某些内容时。你应该确定
在你的任何 'it' 函数中,它应该访问你的变量。
只需将您的测试用例更改为:
describe('Check if VideoListCtrl', function() {
//Add an initialize here:
var $scope = null;
beforeEach(module('videoApp'));
beforeEach(inject(function (_$controller_) {
$controller = _$controller_;
}));
beforeEach(inject(function ($rootScope) {
//new a $scope
$scope = $rootScope.$new();
controller = $controller('VideoCtrl', { $scope: $scope });
}));
it('exists', function() {
expect(controller).not.toBeNull();
});
it('set page size', function () {
expect($scope.setPageSize(12)).toEqual(12);
});
});
或者您可以在 angular document 中查看此内容。
希望这会奏效。 :)
