ruby on rails - Cucumber test redirect -

have found advice: http://openmonkey.com/articles/2009/03/cucumber-steps-for-testing-page-urls-and-redirects

i have added above methods web steps definitons, have written feature, ran , got error nil objects. after investigation, have noticed, have no response , request objects, nil

from web_steps.rb:

then /^i should on (.+?) page$/ |page_name|   request.request_uri.should == send("#{page_name.downcase.gsub(' ','_')}_path")   response.should be_success end  /^i should redirected (.+?) page$/ |page_name|   request.headers['http_referer'].should_not be_nil   request.headers['http_referer'].should_not == request.request_uri   "i should on #{page_name} page" end 

the request , response objects nil, why ?

are using webrat or capybara driver within cucumber? can tell looking @ features/support/env.rb. i'm using capybara, mine includes these lines:

  require 'capybara/rails'   require 'capybara/cucumber'   require 'capybara/session' 

the default used webrat switched capybara, lot of code older examples on web doesn't work properly. assuming you're using capybara too...

request.request_uri - want current_url instead. returns full url of page driver on. less useful getting path, use helper:

def current_path   uri.parse(current_url).path end 

response.should be_success - 1 of biggest frustrations working capybara (and extent, cucumber) is downright zealous interacting user can see. can't test response codes using capybara. instead, should test user-visible responses. redirects easy test; assert page should on. 403s little tricker. in application, that's page title "access denied," test that:

within('head title') { page.should_not have_content('access denied') } 

here's how i'd write scenario test link supposed redirect , not supposed redirect @ other times:

scenario: redirects   given should redirect   when  click "sometimes redirecting link"    should on "redirected_to" page  scenario: not redirect   given shouldn't redirect   when  click "sometimes redirecting link"    <assert should have happened>
