angularjs - How to test an Angular Factory which uses Parse SDK -

-

This is my first question here. I will try my best I have searched a lot before posting

I am developing an angular JS application that is dependent on Javascript. I have assured myself to dive into the test recently, so I am making a start.

I have this factory which wrap around the SDK so that everything is angled in a clean and modular way. That is: SDK is used only through factories (not controlling or directive).

It comes like this: 

  myModule.factory ('UserFactory', ['$ q', function ($ q) {var user = pars.USAR .inded ({// instance}}, {// static / class methods // overrides parse. User.} {Var deferred = $ q.defer (); var current user = pars.USIR. (); if (current User) suspended.Rolove (current user); and deferred.Disclaimed ("no current user"); delay is returned.;}}); Return user;}]);   
 My question:  UserFactory.current ()  How does it use an external service?  I'm jokingly pars SDK, but it does not know how to do this because it is not related to any type (i.e.: httpBackend can not be used).  
 My current test file:  
  ("Unit: UserFinder", function () (every user factor) first (function () (module ("myModule"); Injection (_UserFactory _) {UserFactory = _UserFactory_;}}}}}; user ", function () {// what is expected?});});   
 Thank you from   
 
 
  description ("unit: userfitter", function () (first user) ( Every first) (function () (module ("myModule"); injection (function (_UserFactory _) {UserFactory = _UserFactory_; $ rootScope = _ $ r OotScope_;});}); description ('on'), function () {var success callback, error callback; first (function () {successCallback = jasmine.createSpy ('success'); errorCallback = jasmine.createSpy (' Error ');}); ("Promise should be done if Parse.User.current is true", function () {spyOn (pars user,' on ') .and Thornewell (true); UserFactory.current () Then (success callback, error callback); $ rootsecope. $ Digest (); hopefully (success callback.Count.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
