How to setup PhantomJS with Angular 8? ----> Switched to Puppeteer

Question

I have an Angular 8 application with unit tests and when I run ng test the tests are executed. I want to include the tests in TFS to complete automate my CI/CD pipeline and for that I'm trying to use PhantomJS.

My Current setup is:

Angular CLI: 8.0.4
Node: 12.4.0
OS: win32 x64
Angular: 8.0.2
... animations, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router

Package                           Version
-----------------------------------------------------------
@angular-devkit/architect         0.800.4
@angular-devkit/build-angular     0.800.4

@angular-devkit/build-webpack     0.800.4
@angular-devkit/core              8.0.4
@angular-devkit/schematics        8.0.4
@angular/cdk                      8.0.1

@schematics/angular               8.0.4
@schematics/update                0.800.4
rxjs                              6.5.2

webpack                           4.30.0

My karma.conf.js file:

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-phantomjs-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('karma-junit-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage/FeedbackApp'),
      reports: ['html', 'lcovonly', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml', 'junit'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    captureTimeout: 60000,
    singleRun: true
  });
};

When I run ng test --browsers=PhantomJS I get this errors:

10% building 2/2 modules 0 active26 06 2019 08:55:52.878:INFO [karma-server]: Karma v4.1.0 server started at http://0.0.0.0:9876/

Can anyone help me with this ?

Thanks

UPDATE:

I replaced PhantomJS by Puppeteer, and everything is working now.

Here is what I have done:

npm install --save-dev puppeteer

Changed my karma.conf.js file to look like this:

const process = require('process'); process.env.CHROME_BIN = 
require('puppeteer').executablePath();

module.exports = function (config) {   config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage/FeedbackApp'),
      reports: ['html', 'lcovonly'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['ChromeHeadlessNoSandbox'],
    customLaunchers: {
      ChromeHeadlessNoSandbox: {
        base: 'ChromeHeadless',
        flags: ['--no-sandbox','--headless','--disable-gpu','--disable-translate','--disable-extensions']
      }
    },
    singleRun: true   }); };

Added to scripts section in my package.json:

"test-puppeteer": "ng test --watch=false --source-map=false"

Attention to the --source-map=false - without this it always fails

In TFS, in a custom NPM task:

run test-puppeteer
