我正在尝试对使用某些资源的服务的指令进行单元测试。我遇到的问题是,当我模拟get
资源的方法时,它将被模拟,但不会调用回调函数。因此,结果不会是预期的。
我尝试按照这里spyOn
的建议使用来模拟资源,而且,但都没有奏效。当我调试代码时,它会到达 get 方法,但永远不会调用 get 回调函数,因此,设置我的值的内部回调永远不会被调用。我不确定我的方法是否正确,感谢您的建议。$httpBackend.when
myCallback
/ 资源
.factory ('AirportTimeZone', function($resource){
return $resource('/api/airport/:airportId/timezone',{airportId: '@airportId'});
})
/ 使用我的资源的服务:
angular.module('localizationService', [])
.factory('LocalizationService', ['AirportTimeZone','CurrentLocalization',
function (AirportTimeZone,CurrentLocalization) {
function getAirportTimeZone(airport,myCallback){
var options = {}
var localOptions = AirportTimeZone.get({airportId:airport}, function(data){
options.timeZone = data.timeZoneCode
myCallback(options)
});
}
})
/ 指令
.directive('date',function (LocalizationService) {
return function(scope, element, attrs) {
var airTimeZone
function updateAirportTimeZone(_airportTimeZone){
airTimeZone = _airportTimeZone.timeZone
// call other stuff to do here
}
....
LocalizationService.getAirportTimeZone(airport,updateAirportTimeZone)
....
element.text("something");
}
});
/ 测试
describe('Testing date directive', function() {
var $scope, $compile;
var $httpBackend,airportTimeZone,currentLocalization
beforeEach(function (){
module('directives');
module('localizationService');
module('resourcesService');
});
beforeEach(inject(function (_$rootScope_, _$compile_,AirportTimeZone,CurrentLocalization) {
$scope = _$rootScope_;
$compile = _$compile_;
airportTimeZone=AirportTimeZone;
currentLocalization = CurrentLocalization;
// spyOn(airportTimeZone, 'get').andCallThrough();
// spyOn(currentLocalization, 'get').andCallThrough();
}));
beforeEach(inject(function($injector) {
$httpBackend = $injector.get('$httpBackend');
// $httpBackend.when('GET', '/api/timezone').respond({timeZone:'America/New_York',locale:'us-en'});
// $httpBackend.when('GET', '/api/airport/CMH/timezone').respond({timeZone:'America/New_York'});
}))
describe('Date directive', function () {
var compileButton = function (markup, scope) {
var el = $compile(markup)(scope);
scope.$digest();
return el;
};
it('should',function() {
var html = "<span date tz='airport' format='short' airport='CMH' >'2013-09-29T10:40Z'</span>"
var element = compileButton(html,$scope)
$scope.$digest();
expected = "...."
