How can I test omniauth-facebook in rails 5 with minitest - ruby

Question

I read previous possible questions that may have the answer but that not what I asked for.
First of all I am start to use test. However I already successful setup Omniauth-facebook for my App but still like to go back and test.
-sessions_controller.rb
class SessionsController < ApplicationController
def new
#title= 'Sign In'
end
def create
auth = request.env["omniauth.auth"]
user = User.from_omniauth(auth)
session[:user_id] = user.id
if params.permit[:remember_me]
cookies.permanent[:auth_token] = user.auth_token
else
cookies[:auth_token] = user.auth_token
end
refresh_to root_path, :ma_notice => "Logged in"
rescue
redirect_to root_path, :alert=> "Authentication failed, please try again."
end
def destroy
#session[:user_id] = nil
cookies.delete(:auth_token)
refresh_to root_path, :ma_notice => "Logged Out"
end
def failure
ma_log "Authentication failed, please try again."
redirect_to root_path, :alert=> "Authentication failed, please try again."
end
end
-app/models/user.rb
class User
....
....
def self.from_omniauth(auth)
where(auth.slice(:uid, :provider, :email)).first_or_create do |user|
case auth.provider
when 'identity'
identity = Identity.find auth.uid
user.code = identity.code
user.email = identity.email
else
user.email = auth.info.email
user.uid = auth.uid
user.provider = auth.provider
user.code = auth.info.name
user.role = "M"
end
end
end
def send_password_reset
generate_token(:password_reset_token)
self.password_reset_sent_at = Time.zone.now
save!
UserMailer.password_reset(self).deliver
end
So what I did
Test routes (Its seem simple but sometime I might forgot because I changing from dynamic route to fixed route as required in rails 5.2)
-test/integration/authen_test.rb
require 'test_helper'
class RoutesTest < ActionController::TestCase
test 'facebook login' do
assert_routing '/auth/facebook/callback', {controller: 'sessions', action: 'create',provider: 'facebook'}
end
test 'facebook login post' do
assert_routing({path: '/auth/facebook/callback', method: 'post'},{controller: 'sessions', action: 'create' ,provider: 'facebook'})
end
end
I want to test if facebook accept login and return call back.
-test/models/user_test.rb
require 'test_helper'
class UserTest < ActiveSupport::TestCase
test "Facebook validation" do
auth = {provider: :facebook, FACEBOOK_API: "111111111111111", FACEBOOK_KEY: "11111111111111111111111111111111"}
user = User.from_omniauth(auth)
puts user
assert_not nil
end
end
Problem: It's always green even change FACEBOOK_API. I found the user from puts as well. It's seem like user.from _omniauth already gone to facebook and get info using FACEBOOK_API from .env not one I provided. Then how I can test if it really connected with facebook.
The same with this related test. It's always green in any FACEBOOI_API. That won't work as well.
View Test. I like to test if no facebook login the system or not. The login would display accordingly. Still have no idea as stuck with Q.2 perhap someone could share how you do the test.
To Setup Integration Testing-Omniauth as documented
You can turn on "test mode" for OmniAuth like so:
OmniAuth.config.test_mode = true Once you have enabled test mode, all
requests to OmniAuth will be short circuited to use the mock
authentication hash as described below. A request to /auth/provider
will redirect immediately to /auth/provider/callback.
Then said
OmniAuth.config.add_mock(:twitter, {:uid => '12345'})
OK but where to put that code to turn on
so I assumed the only one is
-config/initializer/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
provider :identity,
:fields => [:code, :email],
:on_failed_registration=> lambda { |env|
IdentitiesController.action(:new).call(env)
}
provider :facebook, ENV['FACEBOOK_API'], ENV['FACEBOOK_KEY']
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:facebook] = :invalid_credentials
end
Here I used test from related question but used my method :create.
It didn't do anything than green, even changed .test_mode = false
-test/integration/sessions_controller_test.rb
require 'test_helper'
class SessionsControllerTest < ActionController::TestCase
test '#signup_success' do
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new({
'provider' => 'facebook',
'uid' => '123451234512345',
'info' => {'email' => 'testuser#testmail.com', 'name' => 'test', 'image' => ''}
})
request.env['omniauth.env'] = OmniAuth.config.mock_auth[:facebook]
get :create
end
end

Answer 1

You can use omniauth test helpers. Here is the link:
https://github.com/omniauth/omniauth/wiki/Integration-Testing
Setup Mock Auth:
OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new({
:provider => 'facebook',
:uid => '123545'
# etc.
})

Answer 2

What i did and what worked for me was setting up mocks in my spec_helper file for various scenarios.
OmniAuth.config.test_mode = true
omniauth_hash = { 'provider' => 'twitter',
'uid' => '12345',
'info' => {
'name' => 'test',
'email' => 'test#test.com',
'nickname' => 'testnick'
},
'extra' => {
'raw_info' =>
{
'location' => 'Coralvilleo'
}
}
}
omniauth_hash_fb = { 'provider' => 'facebook',
'uid' => '12345',
'info' => {
'name' => 'test',
'email' => 'test#testsomething.com'
},
'extra' => {'raw_info' =>
{ 'location' => 'Chicago'
}
}
}
omniauth_hash_fail = { 'provider' => 'facebook',
'uid' => '12345',
'info' => {
},
'extra' => {'raw_info' =>
{ 'location' => 'Chicago'
}
}
}
omniauth_hash_fail_2 = { 'provider' => 'facebook',
'uid' => '12345',
'info' => {
},
'extra' => {'raw_info' =>
{ 'location' => 'Chicago'
}
}
}
omniauth_hash_fail_complete = { 'provider' => 'twitter'}
OmniAuth.config.add_mock(:twitter, omniauth_hash)
OmniAuth.config.add_mock(:facebook, omniauth_hash_fb)
OmniAuth.config.add_mock(:facebook_fail, omniauth_hash_fail)
OmniAuth.config.add_mock(:twitter_fail, omniauth_hash_fail_2)
Then using these methods in my rspec tests for controller like so.
it 'should successfully create a user with twitter' do
request.env['omniauth.auth'] = OmniAuth.config.mock_auth[:twitter]
expect {
post :twitter, provider: :twitter
}.to change{ User.count }.by(1)
end
it 'should redirect the user to the root url with twitter' do
request.env['omniauth.auth'] = OmniAuth.config.mock_auth[:twitter]
post :twitter, provider: :twitter
response.should redirect_to root_path
end
name of the mocks to be specified and linked to what we specified in the helper.
OmniAuth.config.mock_auth[name of the mock you specified in spec helper].
