omniauth mock facebook response - ruby-on-rails

Question

I'm want to test my login through facebook. Im using pure omniauth, w/o Devise. I check the wiki page and do following:
helper for request specs
module IntegrationSpecHelper
def login_with_oauth(service = :facebook)
visit "/auth/#{service}"
end
end
spec_helper.rb
RSpec.configure do |config|
config.include IntegrationSpecHelper, :type => :request
end
Capybara.default_host = 'http://example.org'
OmniAuth.config.test_mode = true
OmniAuth.config.add_mock(:facebook, {
:provider => 'facebook',
:uid => '12345',
:user_info => {
:name => 'dpsk'
}
})
my spec
require 'spec_helper'
describe 'facebook' do
it "should login with facebook", :js => true do
login_with_oauth
visit '/'
page.should have_content("dpsk")
end
end
#OmniAuth routes
match "/auth/:provider/callback" => "sessions#create"
match "/signout" => "sessions#destroy", :as => :signout
match "/signin" => "sessions#signin", :as => :signin
match "/auth/failure" => "sessions#failure", :as => :auth_failure
But in spec nothing returns instead of my mock i got an error:
Failure/Error: visit "/auth/facebook"
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.[]
Where is my error?

Answer 1

My problem was in the mock, its has wrong structure.
OmniAuth.config.mock_auth[:facebook] = {
'user_info' => {
'name' => 'Mario Brothers',
'image' => '',
'email' => 'dpsk#email.ru' },
'uid' => '123545',
'provider' => 'facebook',
'credentials' => {'token' => 'token'}
}

Answer 2

This structure worked for me (December 2016)
OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new({
'provider' => 'facebook',
'uid' => '123545',
'info' => {
'email' => 'dpsk#email.ru',
'name' => 'Mario Brothers',
'image' => '' },
'credentials'=> {
'token'=> '12345',
'expires_at' => 1486718672,
'expires' => true },
'extra' => {
'raw_info' => {
'email' => 'dpsk#email.ru',
'name' => 'Mario Brothers',
'id' => '12345' }
}
})
