How to stub auth0 using sinon in Firebase Functions

[dwmaillist]

I’m trying to make offline testing work for my app, but I’m having trouble stubbing auth0

Stubbing auth0 in firebase functions

You can see above that in my function I call

auth0.getProfile(conv.user.access.token)

I’m simply trying to stub that to return a canned response, but I can’t figure out how to stub the object auth0 from within my test script.

Closing this as @dwmaillist commented in his SO thread what he did to correct, which I am copying in here:

I discovered that rather than initialize the Auth0 AuthenticationClient, I could first require the UsersManager, where the getProfile (which wraps getInfo) is defined.

var UsersManager = require('auth0/src/auth/UsersManager');

In my before() method, I can then create a stub for getInfo, like this

sinon.stub(UsersManager.prototype, 'getInfo').callsFake( function fakeGetProfile() {
  return Promise.resolve({"email": "some.user@company.com"});
});

All the calls to auth0.getProfile then return a Promise that resolves to the document shown in my stub fake function.
