I have been battaling with this for a bit now and cant seem to find the right solution,
i am running an ionic 2 project that uses angular 2's testing environment, when i run ng test using karmas chrome launcher i get the following error:
START:
07 12 2016 11:20:50.590:INFO [karma]: Karma v1.2.0 server started at http://localhost:8888/ 07 12 2016 11:20:50.591:INFO [launcher]: Launching browser Chrome with unlimited concurrency 07 12 2016 11:20:50.682:INFO [launcher]: Starting browser Chrome 07 12 2016 11:20:52.993:INFO [Chrome 55.0.2883 (Linux 0.0.0)]: Connected on socket /#wi3gg8nwMc27F0H4AAAA with id 3728337
Finished in 0.002 secs / 0 secs
SUMMARY: ✔ 0 tests completed
But when using PhantomJS all tests run perfectly.
My system i am running is:
- Linux ubuntu 16.04LT
- NodeJs: 6.9.2
- Npm: 3.10.8
I have tried reinstalling all modules, i have reinstalled OS, i have installed project on another linux system and it works perfectly with the same environment
My karma.conf.js file is as follows
module.exports = function (config) {
config.set({
basePath: '../',
frameworks: ['jasmine', 'angular-cli'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-phantomjs-launcher'),
require('karma-remap-istanbul'),
require('karma-mocha-reporter'),
require('angular-cli/plugins/karma')

Promise.all([

// First, initialize the Angular testing environment.
.then(([testing, testingBrowser]) => {
testing.getTestBed().initTestEnvironment(

})
// Then we find all the tests.
.then(() => require.context('./', true, /\.spec\.ts/))
// And load the modules.
.then(context => context.keys().map(context))
// Finally, start Karma to run the tests.
.then(__karma__.start, __karma__.error);

public static eventFire(el: any, etype: string): void {
if (el.fireEvent) {
el.fireEvent('on' + etype);
} else {
let evObj: any = document.createEvent('Events');

Any Help or direction would be appreciated
