def set_omniauth(opts = {})
  default = {:provider => :facebook,
             :uuid     => "1234",
             :facebook => {
                            :email => "[email protected]",
                            :gender => "Male",
                            :first_name => "foo",
                            :last_name => "bar"
                          }
            }

  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

def set_invalid_omniauth(opts = {})
  
  credentials = { :provider => :facebook,
                  :invalid  => :invalid_crendentials
                 }.merge(opts)
  
  OmniAuth.config.test_mode = true
  OmniAuth.config.mock_auth[credentials[:provider]] = credentials[:invalid]

end 

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
