How do I debug a “[object ErrorEvent] thrown” error in my Karma/Jasmine tests?

阅读更多关于 How do I debug a “[object ErrorEvent] thrown” error in my Karma/Jasmine tests?

I have several failing tests that only output [object ErrorEvent] thrown . I don't see anything in the console that helps me pinpoint the offending code. Is there something I need to do to track these down? [EDIT]: I'm running Karma v1.70, Jasmine v2.7.0 To fix that you have to run your tests without sourcemaps as a workaround: CLI v6.0.8 and above --source-map=false CLI v6.0.x early versions --sourceMap=false CLI v1.x --sourcemaps=false Shortcut ng test -sm=false might also work There is an open issue on that https://github.com/angular/angular-cli/issues/7296 UPDATE : I had that issue as well

问题 I have used in my code like. return $provide.decorator('aservice', function($delegate) { $delegate.addFn = jasmine.createSpy().andReturn(true); return $delegate; }); In that what createSpy do? can i change the createSpy calls to createspyobj calls. By using createSpy, we can create one function/method mocks. Createspyobj can do multiple functions mocks. Am i right? What would be the difference. 回答1: jasmine.createSpy can be used when there is no function to spy on. It will track calls and

问题 EDIT : Quick & Dirty solution at the end of this post I am using a modal window from AngularUI-Bootstrap in the same way that it is explained on the website, except that I splitted files.

Context I created an ApiService class to be able to handle our custom API queries, while using our own serializer + other features. ApiService 's constructor signature is: constructor(metaManager: MetaManager, connector: ApiConnectorService, eventDispatcher: EventDispatcher); MetaManager is an injectable service that handles api's metadatas. ApiConnectorService is a service which is wrapping Http to add our custom headers and signature system. EventDispatcher is basically Symfony's event dispatcher system, in typescript. Problem When I test the ApiService , I do an initialization in beforeEach
