问题 I'm using Karma + Jasmine to test my AngularJS directives, I wrote more than 300 tests and I was very happy... until I found an issue that taken me here because I'm stuck: some tests are failing because they need a CSS applied to some elements (a piece of code in my directive does a size computation based on this style), and despite I added the file containing the CSS implementation, this file seems ignored during tests. In my karma config I added the css file in this way: files: [ // ..

问题 I was wondering if anyone has got grunt karma to run just one spec that is changed on watch. This is my config below. The problem is that the line grunt.config('karma.unit.options.files', filepath); doesn't seem to be doing anything as all the specs still get run however foo does get output before the karma:unit:run gets fired. grunt.initConfig({ karma: { unit: { configFile: 'karma.conf.js', background: true, singleRun: false, options: { files: allFilesArray } } }, watch: { options: { spawn:

问题 I'm working through the Angular2 testing guide and wish to write a test for the ngOnInit() function. The one from the Routing part of the programming guide has this format: let org: Org = null; ngOnInit(): void { let that = this; this.route.data .subscribe((data: { org: Org }) => { that.org = data.org; }); } This is fulfilled through a resolver, like: resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<Org> { let id = this.authService.user.orgId; return this

问题 I want to test the error handling in my Angular2 component and therefore want to mock a service to return an Observable.throw('error'). How can that be done using Jasmine and Karma and Angular 2? 回答1: You should create an observable, and just call the observer error . For example let mockService = { error: false, data: 'something', getData: () => { return Observable.create(observer => { if (this.error) { observer.error(new Error(..)) } else { observer.next(this.data); } observer.complete(); }

问题 How to create a unit test of AngularJS $location service search() method? I am using Jasmine+Karma for the test and AngularJS 1.3, and unit test is new to me :) This is my service, which is working fine in production btw: 'use strict'; (function () { angular.module('myApp') .service('myService', function ($location) { var _customerId = $location.search().id; /*jshint validthis:true */ this.customerId = _customerId; }); })() And this is my serviceSpec: describe('Service: mySerivce', function()

问题 I am using Karma and PhantomJS with Jasmine to test my AngularJS. When I run my gulp test locally it works fine, launches PhantomJS and runs all my tests, but when the tests get run on the build server it fails with the following errors: Note that I am using VSTS and using their built in cloud build system (hosted agent). Having said that its pretty much a task runner and I only use it to run gulp tasks (build, test etc) on checkin [32m13 07 2016 15:21:32.260:INFO [karma]: [39mKarma v1.1.1

问题 I am trying to test a Directive which uses external template. I tried all the following solutions with no luck: ng-directive-testing How to test directives that use templateUrl and controllers? AngularJS + Karma + Ng-html2js => Failed to instantiate module ...html I created a test directive (a simple div) and tested it using an inline 'template' and external 'templateUrl'. The inline solution works while the external doesn't: angular.module('AdUnit').directive('actionButton',function(

问题 I need a way to take a screenshot during a test which uses QUnit and Karma to run inside PhantomJS 2.0.1 I've found this command: window.top.callPhantom('render'); That doesn't throw any error but doesn't seem to work, or at least, I don't know where to look for the taken screenshot. Any clue? 回答1: Found a way! Solution I had to edit my custom PhantomJS custom launcher adding an option: PhantomJSCustom: { base: 'PhantomJS', options: { onCallback: function(data){ if (data.type === "render") {

问题 EDIT: after asking the question, i'm now editing this to elaborate on my findings. My app is modularized using directives. I'm writing my directives such that they (1) create their own scope (2) use templateUrl, and (3) do most of the logic and server data fetching in their controller. The question is how to unit test it, using Mocha with Karma. 回答1: a test is written for each directive. Since the directive uses templateUrl, I used html2js. the html key should be included as a module - that
