我是使用茉莉花编写单元测试用例的新手。我试图在控制器中测试基于资源的服务，从服务器获取实际数据但没有获得所需的结果。如果我做错了，请提供您的意见。以下是我写的单元测试： describe（＆＃39; NewStarterController＆＃39;，function（）{ beforeEach（模块（＆＃39;对myApp＆＃39;））; var scope，ctrl，$ resource;
var context = 'http://localhost.com:8085/AngularPrototype/home';
beforeEach(inject(function(_$resource_, $rootScope, $controller) {
$resource = _$resource_;
NewStarter = {
getNSData : function() {
return $resource(context + '/selfservice/newstarter/get', {}, {
get : {
method : 'GET'
}
});
}
};
scope = $rootScope.$new();
$controller('NewStarterController', {
$scope : scope,
NewStarter : NewStarter
});
}));
it('should test new starter data', function() {
NewStarter.getNSData().get({}).$promise.then(function(response) {
scope.refData = response;
scope.data();
});
expect(scope.data.length).toEqual(2);
expect(NewStarter.getNSData().get.length).toEqual(2);
expect(NewStarter.getNSData().get()).toEqual('formTitleNode');
});
});
Below is the jasmine test result ::

Below is the controller code ( NewStarterController.js ) which is unit tested :
myApp.controller("NewStarterController", ['$scope','$modal', '$state', '$sce', 'NewStarter', function($scope,$modal, $state, $sce, NewStarter) {
$scope.data = function() {
NewStarter.getNSData().get({}, function(response) {
$scope.refData = response;
$scope.formTitle = [];
$scope.displayOptions = [];
angular.forEach($scope.refData.formTitleNode, function(contentItem)
{
var content = -1;
var title = -1;
angular.forEach(contentItem.fieldList, function(fieldBean)
{
if(fieldBean.fieldName == 'TITLE')
{
title = fieldBean.fieldValue;
}
if(fieldBean.fieldName == 'FORMATTEDCONTENTS')
{
content = fieldBean.fieldValue;
}
})
$scope.formTitle.push({title:title, content:content});
})
angular.forEach($scope.refData.displayOptionsNode, function(contentItem)
{
var nsContent = -1;
var nsTitle = -1;
angular.forEach(contentItem.fieldList, function(fieldBean)
{
if(fieldBean.fieldName == 'TITLE')
{
nsTitle = fieldBean.fieldValue;
}
if(fieldBean.fieldName == 'FORMATTEDCONTENTS')
{
nsContent = fieldBean.fieldValue;
}
})
$scope.displayOptions.push({nsTitle:nsTitle, nsContent:nsContent});
$scope.selectedOption = '';
})
$scope.hasNewStarterSubmitted = $scope.refData.hasNewStarterSubmitted;
$scope.submittedSelectedOption = $scope.refData.submittedSelectedOption;
$scope.submittedStudentLoan = $scope.refData.submittedStudentLoan;
$scope.nsAlreadySubmittedValidationMsg = $scope.refData.nsAlreadySubmittedValidationMsg;
console.log('Success', response);
}, function(error) {
//alert(JSON.stringfy(error))
$scope.contentLoadErrorMsg=error.data;
//console.error('ERR', error);
});
}
}]);
Below is the code in services.js
myApp.factory('NewStarter', function($resource, context) {
return {
getNSData: function() {
return $resource(context + '/selfservice/newstarter/get', {}, {get: {method:'GET'}});
},
submitNSForm: function() {
return $resource(context + '/selfservice/newstarter/submit', {}, {submit: {method:'POST'}});
}
}
});
Below is the code in myApp.js
var myApp = angular.module('myApp', ['ngResource', 'ngSanitize', 'ui.bootstrap', 'ui.router']);
myApp.constant('context', '/AngularPrototype/home');
myApp.constant('projectName', '/AngularPrototype');
myApp.config(function($stateProvider, $urlRouterProvider, projectName) {
$urlRouterProvider.otherwise('/home');
$stateProvider .state('newStarter', {
url:'/newstarter',
templateUrl: projectName + '/newstarter',
controller: 'NewStarterController'
})
});
Thanks!
Below i tried as per your suggestion but getting error while running the unit test:
describe('NewStarterController', function() {
beforeEach(module('myApp'));
var scope, postDefer,NewStarter;
beforeEach(inject(function(_NewStarter_, $rootScope, $controller,$q) {
NewStarter = _NewStarter_;
postDefer = $q.defer();
spyOn(NewStarter,'getNSData').and.returnValue(postDefer.promise);
scope = $rootScope.$new();
$controller('NewStarterController', {
$scope : scope,
NewStarter : NewStarter
});
}));
it('should test new starter data', function() {
NewStarter.getNSData().get({});
postDefer.resolve();
scope.$apply();
expect(scope.data.length).toEqual(2);
});
});
Below are the errors while running the test :
Error:[$injector:unpr] Unknown provider: NewStarterProvider <- NewStarter
typeError: Unable to get property 'getNSData' of undefined or null reference
答案 0 :(得分：0)
由于它是一个单元测试，你需要专注于测试单个单元，你应该尝试尽可能地模拟所有依赖项。话虽如此，在单元测试中使用真正的$资源是不可取的。
我认为你应该做的是： - 1.模拟NewStarter.getNSData（），或在控制器中调用的任何服务方法 2.返回一个假的资源对象 3.模拟获取假资源的方法（因为它是你的控制器中使用的）并返回一个promise 4.解决测试成功处理程序的承诺。
