Mocking user / session with passportJS authentication. This gist helps you test code that requires a user that has been authenticated by passport JS

mock-passport-middleware.coffee

module.exports =
 
  initialize: (sessionUserObject) ->
 
    (req, res, next) ->
      passport = @
      passport._key = 'passport'
      passport._userProperty = 'user'
      passport.serializeUser = (user, done) -> done null, user
      passport.deserializeUser = (user, done) -> done null, user
 
      req._passport = instance: passport
 
      req._passport.session = user: sessionUserObject
 
      next()

test-app.coffee

express = require 'express'
passport = require 'passport'
passportMock = require './mock-passport-middleware'
 
mockUser = name: { givenName: "Jonathon", familyName: "Kresner" }
 
global.app = express()
 
app.configure ->
  app.use express.static(__dirname + '/public')
  app.use express.bodyParser()
  app.use express.cookieParser()
 
  app.use express.session { secret: 'your secret' }

  # use our passportMock middleware instead of original passport.initialize()
  # app.use passport.initialize()
  app.use passportMock.initialize( mockUser )  # pass in the object wanted as session/user
  app.use passport.session()
