Angular6 - cannot resolve 'fs' in selenium-webdriver\lib

I had the same issue with ng test on

Angular CLI: 6.1.2 Node: 8.9.1

The problem for me was using the

wrong HttpClient. import in my test file.

Make sure your HttpClient is from '@angular/common/http'; and not imported from Selenium.

Hope this helps :)

I had the same issue, because it imported EventEmitter from 'protractor' instead of angular-core

For some reasons my IntelliJ added:

import { beforeEach } from 'selenium-webdriver/testing';

which was causing the issue. Removing it solved the problem for me.
