Shoulda + Factory_Girl + Webrat for Rails Integration Tests

November 14, 2008 at 08:11 AM · Posted under BDD, Rails, factory_girl, shoulda

Is anyone else using shoulda, factory_girl and webrat for Rails integration tests?

I did a quick search and found Daniel Wellman using it in integration tests minus shoulda and factory_girl. I really like adding shoulda to get the contexts and factory_girl is a great replacement for fixtures. When combined with webrat it really makes for some easy to read integration tests. By the way, I'm already using shoulda and factory_girl for my unit and functional tests.

Here is an example I whipped up last night. It's nothing fancy. I'll probably make some modifications in the future, but so far I'm happy with it. I'm loading webrat in my test_helper.

require '../test_helper'

class AdminLoginTest < ActionController::IntegrationTest
  context 'An employee' do
    setup do
      @employee = Factory(:employee)
    end

    should 'be able to login with a valid username and password' do
      visit '/admin'
      assert https?
      assert_equal '/admin/sessions/new', path
      fills_in 'Email', :with => @employee.user.email
      fills_in 'Password', :with => @employee.user.password
      clicks_button 'Log In'
      assert_equal @employee.user.id, session[:user_id]
    end

    should 'be denied access with an invalid username or password' do
      visit '/admin'
      assert https?
      assert_equal '/admin/sessions/new', path
      fills_in 'Email', :with => @employee.user.email
      fills_in 'Password', :with => 'wrongpassord'
      clicks_button 'Log In'
      assert_nil session[:user_id]
    end
  end
end

This is testing a simple login to the admin section of a project I'm working on. We're using restful_authentication. Each line of each test is essentially an assertion. If something doesn't respond with a success or a form field is missing, the test fails.

We're using shoulda / factory_girl / webrat for testing on one project. It is quite a thrill to work with. Shoulda macros goes a long way to making integration tests more readable, especially when coupled with hpricot. Yes, once they break, it can sometimes be a bit of a pain figuring out where an error originated. Perhaps I should do a blog entry with example shoulda macros, to get some feedback on the sanity of them? Webrat does have a very annoying feature where it opens browser windows for broken tests, when running through autotest on OS X. I haven't been able to eliminate this issue, and it even happens on our CruiseControl.rb server, which is running OS X Server.

Glad you've been enjoying Webrat. Please let me know if there's anything that gives you trouble. Morgan -- In the latest Webrat code, there's a setting to disable this. Try: Webrat.configure do |config| config.open_error_files = false end Latest code is at: http://github.com/brynary/webrat

Bryan, that's cool. I'll be sure to upgrade our project with a later version of Webrat, and will check out the configuration options :-)
