             :facebook => {
                            :email => "[email protected]",
                            :gender => "Male",

  credentials = default.merge(opts)

  user_hash = credentials[provider]

  OmniAuth.config.test_mode = true

  OmniAuth.config.mock_auth[provider] = {

end

                 }.merge(opts)
  
  OmniAuth.config.test_mode = true
  OmniAuth.config.mock_auth[credentials[:provider]] = credentials[:invalid]

end 

have the problem with testing devise

class ArticlesControllerTest < ActionController::TestCase
  setup do
    default = {:provider => :facebook,
               :uuid     => "1234",
               :facebook => {
                 :email => "[email protected]",
                 :gender => "Male",
                 :first_name => "foo",
                 :last_name => "bar"
               }
    }
    opts = {}
    credentials = default.merge(opts)
    provider = credentials[:provider]
    user_hash = credentials[provider]

    OmniAuth.config.test_mode = true

    OmniAuth.config.mock_auth[provider] = {
      'uid' => credentials[:uuid],
      "extra" => {
        "user_hash" => {
          "email" => user_hash[:email],
          "first_name" => user_hash[:first_name],
          "last_name" => user_hash[:last_name],
          "gender" => user_hash[:gender]
        }
      }
    }
  end
  test "should get index" do
    get :index
    assert_response :success
  end
end

but I have an error ActionView::Template::Error: No route matches {:controller=>"users/omniauth_callbacks", :action=>"passthru", :provider=>:facebook}

What should I do?

Thanks for this, I was having an issue with invalid credentials when running a test after calling OmniAuth.config.mock_auth[:facebook] = :invalid_credentials on a previous test.

This approach lets me control the credentials that are being supplied with greater accuracy.

  OmniAuth.config.mock_auth[provider] = {
    'uid' => credentials[:uuid],
    "extra" => {
    "user_hash" => {
      "email" => user_hash[:email],
     etc. etc. etc.

After supplying the above, it does not seem to be saving all the pertinent details in the request.env["omniauth.auth"] hash. Am having problems with the integration test. advice much appreciated
