Rails rspec and omniauth (integration testing) - ruby-on-rails-3

Question

My Rails 3.2 app uses OmniAuth and Devise to sign in with Twitter. The authentication system works fine. I would like to write an integration test in rspec to make sure everything works. Using the information in the wiki, I've written the following, but I know I'm missing things.
Under test.rb in config/environments, I have the following lines
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:twitter] = {:provider => 'twitter', :uid => '123545'}
My rspec test looks like this:
describe "Authentications" do
context "without signing into app" do
it "twitter sign in button should lead to twitter authentication page" do
visit root_path
click_link "Sign in with Twitter"
Authentication.last.uid.should == '123545'
end
end
end
Authentication is the name of my model and calling .uid in rails console returns the string fine.
I'm getting the following error when I run this test:
Failure/Error: Authentication.last.uid.should == '123545'
NoMethodError:
undefined method `uid' for nil:NilClass
Can anyone help me figure out how to use the OmniAuth mocks that are provided? An explanation for why and how it works would be appreciated as well.

Answer 1

I run into something similar.
After changing my mock object from using symbol keys:
OmniAuth.config.mock_auth[:twitter] = {
:uid => '1337',
:provider => 'twitter',
:info => {
:name => 'JonnieHallman'
}
}
to using string keys:
OmniAuth.config.mock_auth[:twitter] = {
'uid' => '1337',
'provider' => 'twitter',
'info' => {
'name' => 'JonnieHallman'
}
}
it worked.
And do you have
request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:twitter]
somewhere in your testcase?

Answer 2

Did you try moving these two lines to spec_helper.rb?
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:twitter] = {:provider => 'twitter', :uid => '123545'}
Also add the following before block in your test file:
before do
request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:twitter]
end

Answer 3

I highly suggest this answer
In short...
Set up the mock
Make the request
Test whatever code is attached to the callback
For example: test the session['uid'] was set (although, I opt to test only what the user sees, or, rather, does not see)
My code...
config/environments/test.rb
Rails.application.configure do
...
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:linkedin] = {
'provider' => 'linkedin',
'uid' => '123545',
'info'=>
{ 'email'=>'infinite#jest.com',
'first_name'=>'Dave',
'last_name'=>'Wallace' }
}
end
spec/features/sign_in_feature_spec.rb
require 'rails_helper'
feature 'Sign in with LinkedIn' do
before do
OmniAuth.config.add_mock(:linkedin, {:uid => '12345'})
end
let(:user) { create(:user) }
scenario 'with valid email and password' do
visit '/'
expect(page).to have_no_content 'Sign Out'
click_link 'nav-sign-in' # image/button: Sign in with LinkedIn
expect(page).to have_content 'Sign Out'
end
end
Let me know if/how I may improve this solution (and my code!)

Answer 4

Selected solution does not work for me.
My solution i get from https://gist.github.com/kinopyo/1338738
and official doc https://github.com/intridea/omniauth/wiki/Integration-Testing
here:
# in spec/support/omniauth_macros.rb
module OmniauthMacros
def mock_auth_hash
# The mock_auth configuration allows you to set per-provider (or default)
# authentication hashes to return during integration testing.
OmniAuth.config.mock_auth[:odnoklassniki] = OmniAuth::AuthHash.new({
:provider => 'odnoklassniki',
:uid => '123545',
:info => OmniAuth::AuthHash::InfoHash.new({
:name => 'mockuser'
})
})
end
end
# in spec/spec_helper.rb
RSpec.configure do |config|
# email spec
config.include(EmailSpec::Helpers)
config.include(EmailSpec::Matchers)
end
OmniAuth.config.test_mode = true
# in spec example:
visit new_user_registration_path
mock_auth_hash
find('#btn-odnoklassniki').click # here is link generated as omniauth_authorize_path(resource_name, provider)
