Debugging cucumber scripts, cucumber and devise authentication

Non Rails/Ruby people may as well ignore this one!

Sometimes you need to see what the web server is sending back, when I'm working on rspec scripts I can print things out (which messes up the pretty output) but then see where my assumptions are wrong. I needed to be able to see what was in the response so that I could work out what was wrong. It's annoyingly easy when you work out how. You need to add a step that looks like this:

When /^I dumped the response$/ do
     puts response.body
end

Then, in the features that are giving trouble:

Scenario: creator restores fragment
  When fragment 1 exists
  And I am the fragment owner
  And I am on the fragment
  And I dumped the response
  # ...

This allows you to do some debugging on that error you can't fathom out. It helped me greatly when I put in devise authentication and discovered that my code was looping back to the login screen because of a duff password.

Devise

I love this plugin - takes away a ton of work

(Thanks Colin)

This should get you started with cucumber. Note that password is a helper method that just returns something like 'test123'. My code has user roles (I do it differently from the way the devise guys do it) and I took it out, so it may not run straight away as it's untested. Caveat emptor.

def create_my_user(params)
  unless user = User.find_by_email(params[:email])
    params[:password_confirmation] = params[:password]
    user = User.create!(params)
    # This makes the user look 'confirmed'
    user.update_attribute(:confirmation_token,nil)
    user.update_attribute(:confirmed_at,Time.now)
  end
  user
end

Given /^I am logged in as (.*)$/ do |email|
  @current_user = create_my_user(:email => email, :password => password )
  visit new_user_session_path
  fill_in("Email", :with => email )
  fill_in("Password", :with => password )
  click_button("Sign in")
  response.body.should =~ /My Lovely App/m
end
