我正在为我的 DetailCtrl 编写 jasmine 测试。我有 10 个 json 文件,每个文件的文件名都是这样
1.json
2.json
3.json
在我的数据文件夹中
这是我的详细控制
backpagecontrollers.controller('DetailCtrl', function($scope, $stateParams, $http) {
$http.get('data/' + $stateParams.listingId + '.json').success(function(data) {
$scope.extrainfo = data;
});
});
细节 Controller 正在从我的数据文件夹中获取每个 1.json、2.json、3.json 文件。
这是我的部分路线
.state('listingdetail', {
url: "/listings/:listingId",
templateUrl: "partials/detail.html",
controller: 'DetailCtrl'
})
让我们回到测试中,我将 $stateParams
和 $state
都注入(inject)了测试。
我想测试上面的每个 json 文件是否存在我的 json 文件中的图像。
我正在设置 httpbackend 以获取本地主机 url 加上来自 $stateparams
的 listingId,我将其配置为路由的一部分,但 listingId
返回时未定义。我应该在我的测试中注入(inject)其他东西吗?
describe('Detail Ctrl', function() {
var scope, ctrl, httpBackend, stateparams, listingId;
beforeEach(angular.mock.module("backpageApp"));
beforeEach(angular.mock.inject(function($controller, $rootScope, _$httpBackend_, $stateParams, $state) {
httpBackend = _$httpBackend_;
stateparams = $stateParams;
listingId = stateparams.listingId;
httpBackend.expectGET('http://localhost:8000/#/listings/' + listingId).respond([{id: 1 }, {id: 2}, {id:3}, {id:4}, {id:5}, {id:6}, {id:7}, {id:8}, {id:9}, {id:10}]);
scope = $rootScope.$new();
ctrl = $controller("DetailCtrl", {$scope:scope});
}));
it('the images for each listing should exist', function() {
httpBackend.flush();
expect(scope.images).toBe(true)
});
});
我收到这个错误
Error: Unexpected request: GET data/undefined.json
Expected GET http://localhost:8000/#/listings/undefined
最佳答案
我认为您可能误解了路由器是如何与 Controller 协同工作的。当您对 Controller 进行单元测试时,您不会执行路由或进入 ui-router 状态。这些状态和路由是应用程序正常运行时触发 Controller 执行的内容。但是在单元测试中,您正在使用 $controller 显式执行 Controller 。所以你完全跳过了路由部分。这意味着您需要模拟 ui-router 通常会为您创建的对象 $stateparams。
describe('Detail Ctrl', function() {
var scope, ctrl, httpBackend, stateparams, listingId;
beforeEach(angular.mock.module("backpageApp"));
//don't need to inject state or stateparams here
beforeEach(angular.mock.inject(function($controller, $rootScope, _$httpBackend_) {
httpBackend = _$httpBackend_;
stateparams = { listingId: 1 }; //mock your stateparams object with your id
//you should be expecting the get request url from the controller, not the route
httpBackend.expectGET('data/' + stateparams.listingId + '.json').respond([{id: 1 }, {id: 2}, {id:3}, {id:4}, {id:5}, {id:6}, {id:7}, {id:8}, {id:9}, {id:10}]);
scope = $rootScope.$new();
//pass your mock stateparams object to the controller
ctrl = $controller("DetailCtrl", {$scope:scope, $stateParams:stateparams});
}));
it('the images for each listing should exist', function() {
httpBackend.flush();
//I don't see images set in your controller, but you
//could check scope.extrainfo here
expect(scope.images).toBe(true)
});
});
