$http.timeout in unit test and $httpBackend.flush()

[mko...@koukaam.se]

Hi, I am new to angularJS.

I use grunt and karma to develop simple web application and try to write tests whenever possible.

I use angular 1.2.0 rc2 (had the same problem with rc1) and have problem/answer I hope someone can answer me.

I have follwing test case, I have simplified it and reduced it:

it('should abort post request', inject(function($http, $q, $rootScope) {

var canceller = $q.defer();

$http({

method: 'POST',

url: '/xml',

data: '<ping/>',

timeout: canceller.promise,

headers: {

'Content-Type': 'application/xml; charset=utf-8',

'Accept': 'application/xml'

}

});

$rootScope.$digest();

canceller.resolve(); //now the request should be aborted and no request should be pending...

$rootScope.$digest();

}));

What I want to do, is to test that I can abort my request. Based on http://docs.angularjs.org/api/ng.$http  I've used a promise as a timeout.

If I run this test, I receive error "Unflushed requests: 1"

My question is:

Why is do I need to call $httpBackend.flush(); so the test can pass. The request should have been aborted, right? 

Is there something I am missing?

Thank you for guidance
