我正在嘗試使用Karma和Jasmine對我的AngularJS應用程序進行單元測試。我想嘲笑$ http服務。爲此,我使用$ httpBackend方法。下面是我的服務,我想測試:
angular.module('MyModule').factory('MyService', function($http, $log, $parse, $q, $timeout, $filter, MyOtherService1, MyOtherService2){
var service = {};
service.getSomething = function(id){
return $http.get('/somePath/subpath/' + id);
}
});
這項服務我的單元測試是:
describe("myTest", function(){
var myService, $httpBackend, scope, mockMyOtherService1, mockMyOtherService2;
var myResponse =
{
foo:'bar'
};
beforeEach(module("MyModule"));
beforeEach(inject(function(_MyService_, $injector){
$httpBackend = $injector.get('$httpBackend');
myService = _MyService_;
scope = $injector.get('$rootScope').$new();
mockMyOtherService1 = $injector.get('MyOtherService1');
mockMyOtherService2 = $injector.get('MyOtherService2');
}));
beforeEach(function(){
//To bypass dependent requests
$httpBackend.whenGET(/\.html$/).respond(200,'');
});
//If I uncomment the below afterEach block, the same error is shown at next line.
/*afterEach(function() {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});*/
//This test passes successfully
it("should check if service is instantiated", function() {
expect(myService).toBeDefined();
});
//This test passes successfully
it("should expect dependencies to be instantiated", function(){
expect($httpBackend).toBeDefined();
});
//The problem is in this test
it("should get the getSomething with the provided ID", function() {
$httpBackend.whenGET('/somePath/subpath/my_123').respond(200,myResponse);
var deferredResponse = myService.getSomething('my_123');
//The error is shown in next line.
$httpBackend.flush();
//If I comment the $httpBackend.flush(), in the next line, the $$state in deferredResponse shows that the Object that I responded with is not set i.e. it does not matches the 'myResponse'.
expect(deferredResponse).toEqual(myResponse);
});
});
這是一個緊急的問題,我需要儘快就同一幫助。我會非常感謝你的回答。
這不適用於我:P –
