  Scenario: create resource from one time request
    Given I am an admin

# step definitions using Rack::Test
When /^I make an authenticated request for a new resource$/ do
  post resources_path, :auth_token => @admin.authentication_token
  follow_redirect!
end

Then /^I am redirected$/ do
  last_response.should_not be_redirect
  last_request.env["HTTP_REFERER"].should include(resources_path)
end

Then /^I see the message "([^"]*)"$/ do |msg|
  last_response.body.should include(msg)
end
