Hi guys, I have strange problem with getting model expectations to work with Cucumber. My setup is that I use Cucumber + Webrat (Selenium backend). Story I test is registering user on site. Cucumber runs story perfectly fine, and I see it fills in form, sends it, I even see proper "You have successfully registered" message at the end. However, as a last element of story I want to make sure the user was really created in database - and this fails. I have definition of following step: Then /^should exist exactly "(.*)" users$/ do |cnt, state| User.count.should == cnt.to_i end However, it always complains that there are 0 users, when expected X. What is even more stranger, when I log into console, and do User.count, I get proper number of users - they were actually created during running a story! Any ideas?

The step definition is actually: Then /^should exist exactly "(.*)" users$/ do |cnt| User.count.should == cnt.to_i end but that doesn't change anything, please help!

In your env.rb file do you have the following? Cucumber::Rails.use_transactional_fixtures If so that is your problem. What is happending is that you two separate processes and two separate DB connections going. One is running the server for selenium, and the other is for your features. With transactional_fixtures turned on all of your DB calls for each scenario are wrapped in into a transaction that is rolled back at the end. Be default MySQL, and most other DBs I would imagine, don't let the data in a transaction appear to any other queries until that transaction is actually committed. That is why you can see the correct count in the process running the features but not the selenium process. How do you get around this? You could change your settings on MySQL, but I wouldn't suggest that. What I do is turn off transactional_fixtures and then manage the DB cleanup myself in After blocks. The quick and dirty way to do this is to truncate your tables.. There have been some threads on this list explaining how to do this. There are some other ways to accomplish this without resorting to truncating everytime too, but I will let you google and find those threads. This problem seems to come up quite a bit.. we should probably add this to the Troubleshooting page on Cucumber's wiki.... Anyways, I hope that helps. -Ben

I have updated Troubleshooting page in Github wiki like you suggested so that other people might find solution quicker than me :). One more time - thanks!
