Tests with Karma/Jasmin?

[BaruchDavid]

Hello, i'am trying ti implement some tests, to test my implementation with ng-idle, but it fails:
Test-Code:

import { Router } from '@angular/router';
import {async} from '@angular/core/testing';
import { inject, TestBed } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { TimeoutService } from './timeout.service';
import { CoreTestingModule } from '../../core-testing.module';

fdescribe('TimeoutService', () => {
    let router: Router;
    let service: TimeoutService;
    const spies = {
        navigate: null
    };

    beforeEach(async(() => {
        TestBed.configureTestingModule({
            imports: [RouterTestingModule, CoreTestingModule],
            providers: [TimeoutService]
        });
        //spies.navigate = spyOn(router, 'navigate').and.stub();
        service = TestBed.get(TimeoutService);
    }));


    fit('should navigate to index after 15 Seconds', () => {
        service.setIdleTime(10);
        service.setTimeoutTime(5);
        console.log('TEST FINISHED');
        //expect(spies.navigate).toHaveBeenCalledWith(['/index']);
    });
});

My karma.conf.json

module.exports = function (config) {
config.set({
basePath: '..',
frameworks: ['jasmine', 'intl-shim', '@angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-intl-shim'),
require('karma-chrome-launcher'),
require('karma-jasmine-html-reporter'),
require('karma-junit-reporter'),
require('karma-coverage-istanbul-reporter'),
require('@angular-devkit/build-angular/plugins/karma')
],
files: [
'node_modules/intl/locale-data/jsonp/de-DE.js',
'node_modules/ng-idle/angular-idle.min.js'
],
coverageIstanbulReporter: {
dir: require('path').join(__dirname, 'coverage'),
reports: ['html', 'lcovonly', 'cobertura'],
fixWebpackSourcePaths: true
},
client: {
clearContext: true // leave Jasmine Spec Runner output visible in browser
},

    reporters: ['progress', 'kjhtml', 'junit'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_ERROR,
    autoWatch: false,
    browsers: ['ChromeHeadlessNoSandbox'],
    customLaunchers: {
        ChromeHeadlessNoSandbox: {
            base: 'ChromeHeadless',
            flags: [
                '--no-sandbox'
            ]
        }
    },
    singleRun: true,
    browserNoActivityTimeout: 100000,
    restartOnFileChange: true
});

};

But i get error:
