使用模拟数据的Jasmine $ HTTP请求

Question

我试图测试$ http请求，无论我做什么，我似乎无法让它工作。我有一个工厂，它拥有4个请求类型GET，POST，PUT，DELETE。

我试图测试来自get请求的响应，但我在控制器中分配响应的scope变量给出了一个错误或undefined =来自get请求的响应。

工厂代码如下：

app.factory('requestService', ['$http', function ($http) {
// reusable requests
return {
    //reuable get request
    getRequest: function (url) {
        return $http({
            method: 'GET',
            dataType: "json",
            url: url
        });
    },
    //reuable post request
    postRequest: function (url, data) {
        return $http({
            method: 'POST',
            data: data,
            url: url
        });
    },
    //reuable put request
    putRequest: function (url, data) {
        return $http({
            method: 'PUT',
            data: data,
            url: url
        });
    },
    //reuable delete request
    deleteRequest: function (url) {
        return $http({
            method: 'DELETE',
            url: url
        });
    }
}
}]);

以下是控制器中的内容。

    //get the teams
    $scope.getTeams = function(){
    requestService.getRequest('https:.../teams').then(function (response) {
        $scope.teams = response;
    });
}
$scope.getTeams();

茉莉花代码：

describe('Controller Test', function() {
var $rootScope, controller;

//Tell the $httpBackend to respond with our mock object
var teamsResponse = {// Teams Data //};

beforeEach(function() {
    module('myApp')
});    
beforeEach(inject(function($rootScope, $controller, _$httpBackend_, $http) {
    $scope = $rootScope.$new();
    controller = $controller;
    controller('Controller', {$scope: $scope});

    $httpBackend = _$httpBackend_;

    $httpBackend.whenGET('https:...../teams').respond(200, teamsResponse);

}));

it('should load a list of teams', function() {
    $scope.getTeams();
    $httpBackend.flush();

    expect($scope.teams).toBe(teamsResponse);
});
});

我得到的错误是：

预期未定义为{//团队数据//}

Answer 1

describe("Testing Common Get JSON Service", function () {

    var service, $httpBackend;

    beforeEach(inject(function($injector,$rootScope) {
        service = $injector.get('CommonService');
        $httpBackend = $injector.get('$httpBackend');
        scope = $rootScope.$new();
        successCallback = jasmine.createSpy();
        errorCallback = jasmine.createSpy();

        $httpBackend.when('GET', getFlightIncidentLookupUrl).respond(getFlightIncidentLookup);
        successCallback();
    }));

    afterEach(function() {
        $httpBackend.verifyNoOutstandingExpectation();
        $httpBackend.verifyNoOutstandingRequest();
    });

    it('test getServiceJSON works fine and calls a GET method', function () {
        service.getServiceJSON(getFlightIncidentLookupUrl).then(function(response) {
            expect(response.data.incidentLookup.length).toEqual(1);
        });
        $httpBackend.flush();
    });


});

这对我有用。这里CommonService是Angular js中的一个服务，它调用get方法。我得到了正确的答复。
