I am trying to test the login service using some mock data. Using AuthGuard, secured routes are locked and so upon successful login, it will check the localStorage if there's an authToken.

This is unfortunately failed because Protractor is running in a Node context.

Failed: Error: Uncaught (in promise): ReferenceError: localStorage is not defined ReferenceError: localStorage is not defined at RESTService.getAuthToken

This is in the protractor.conf.js:

beforeLaunch: function() {
    require('ts-node').register({
      project: 'e2e'
    });
},

Also, Protractor requires zone-node to run.

In which case, how do I resolve this?

Can you also paste your code here to get the localstorage / which is causing the error? – wswebcreation Jun 30 '17 at 04:30
Sorry for my late reply. It's just return localStorage.getItem(AUTH_TOKEN_KEY); – Sorakthun Ly Jul 03 '17 at 06:56
Tnx, but please paste your code, that is used to get the localstorage, so the complete method, here. – wswebcreation Jul 03 '17 at 06:58
Which part of the code sorry? – Sorakthun Ly Jul 03 '17 at 06:59
It's related to this https://github.com/NathanWalker/angular-seed-advanced/issues/67 – Sorakthun Ly Jul 03 '17 at 07:00
There's an error with Protractor missing zone – Sorakthun Ly Jul 03 '17 at 07:01
So I had to add require('zone.js/dist/zone-node'); to the protractor.conf.js, onPrepare function, which allows it to run. But it fails because it is now running within Node context. – Sorakthun Ly Jul 03 '17 at 07:02
It works on normal test except where localStorage call occurs inside the code. – Sorakthun Ly Jul 03 '17 at 07:02
that was the rest of the method: getAuthToken(): string { return localStorage.getItem(AUTH_TOKEN_KEY); } – Sorakthun Ly Jul 03 '17 at 07:04
