我有控制器:
(function () {
'use strict';
angular.module('myApp').controller('myCtrl', function ($scope, myService) {
// Start -----> Service call: Get Initial Data
myService.getInitialData().getData(function (featureManagerdata) {
var serviceData = featureManagerdata;
}, function (error) {
showErrorMessage(error, 'getinitialdata');
});
});
}());
这是我的服务:使用$ resource调用getInitialData并将getData作为自定义函数。
(function () {
'use strict';
angular.module('myApp').factory('myService', ['$resource', myService]);
function myService($resource) {
var hostUrl = 'http://x.x.x.x/WebAPIDev';
function getInitialData() {
var url = hostUrl + '/featuremanager/allfeatures';
var options = {
getData: {
method: 'GET',
isArray: true
}
};
return $resource(url, {}, options);
);
return {
getInitialData: getInitialData
};
}
}());
想要使用karma-jasmine来测试控制器中的服务调用:
TestMyCtrl:
describe('Test my controller', function() {
beforeEach(module('myApp'));
var scope, Ctrl, service;
angular.module('myApp').service('mockService', function($resource) {
getInitialData = function() {
return {
'featureId': 1
};
}
});
beforeEach(inject(function(_$controller_, $rootScope, mockService) {
scope = $rootScope.$new();
Ctrl = _$controller_('myCtrl', {
$scope: scope,
service: mockService
});
}));
it('should test get initial data', function() {
var response, mockUserResource, $httpBackend, result;
service.getInitialData().getData(function(data) {
response = data;
// verify data
});
});
});
抛出错误,service.getInitialData不是函数。知道为什么它会抛出错误或任何其他更好的方法来测试服务调用
答案 0 :(得分:1)
在Angular中,factory
和service
之间存在一些差异,如果您想了解更多信息,请查看Service vs Factory vs Provider in Angular。
其中一个是工厂返回参考对象,服务返回实例
因此,当您尝试在工厂中定义/模拟某个函数或属性时,返回一个带有属性名称和值的Object
,但在服务中,您应该将其设置为this
< / strong>即可。
除此之外,你应该返回一个定义函数getData
的Object,以便在上一个测试用例中调用它。(或者它会抛出 undefine不是函数错误)
因此,请将TestMyCtrl
更新为此
describe('Test my controller', function() {
beforeEach(module('myApp'));
var scope, Ctrl, service;
angular.module('myApp').service('mockService', function($resource) {
//set the function to this.
this.getInitialData = function() {
//return {
// 'featureId': 1
//};
//return an object which defined getData function.
return {
getData: function(func) {
var data = {
featureId: 1
};
//do something here if you want.
func(data);
}
};
}
});
beforeEach(inject(function(_$controller_, $rootScope, mockService) {
scope = $rootScope.$new();
Ctrl = _$controller_('myCtrl', {
$scope: scope,
service: mockService
});
}));
it('should test get initial data', function() {
var response, mockUserResource, $httpBackend, result;
service.getInitialData().getData(function(data) {
response = data;
// verify data
});
});
});
希望这可以回答你的问题。 :)
