我正在尝试对使用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,当我模拟资源的get
方法时,它将被模拟,但不会调用回调函数。因此,结果将不是预期的结果。
我尝试使用spyOn
建议here以及$httpBackend.when
来模拟资源,但都没有效果。当我调试代码时,它将转到get方法但get调用函数永远不会被调用,因此,设置我的值的内部回调myCallback
永远不会被调用。
我不确定我的方法是否正确,我感谢您的建议。
/资源
.factory ('AirportTimeZone', function($resource){
return $resource('/api/airport/:airportId/timezone',{airportId: '@airportId'});
})
/正在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 = "...."
expect(element.html()).toBe(expected);
});
});
})
答案 0 :(得分:4)
如上所述:
使用$httpBackend.when
设置回复后,您仍然需要调用$httpBackend.flush()
来清除模拟回复。
