Newb struggling to get/keep RSpec stable

Long post but prolly simple if you understand Rails, RSpec &
differences between webrat & capybara.

I’m hoping someone can take a few moments to help me get a better
understanding of my environment. I have a somewhat intermediate
understanding of Ruby/Rails but a beginner’s understanding of RSpec. I
have purchased The RSpec Book and, though helpful, leaves me with more
questions…probably from the very beginning I missed some basic
points…as just understanding HOW the environment is set up, WHERE/
WHY it looks for files to test and WHAT matchers, etc. are available
in tests is confusing me.

Anyway, in trying to wrap my head around RSpec I created a simple
Rails3 project. Altered the Gemfile to:

group :development, :test do
gem ‘rspec-rails’
gem ‘webrat’
gem ‘haml-rails’
gem ‘sass’
gem ‘spork’, ‘~> 0.9.0.rc’
end

group :test do
gem ‘rspec’
end

Generated some scaffolding and starting making and editing some
specs… I was happy!

Now, after some stability and growing confidence I decided I’d try to
swap out webrat and replace it with capybara (which I’ve heard good
things about especially when dealing with javascript tests). So I
commented out “# gem ‘webrat’” and

  • added:

    gem ‘capybara’, :git => ‘git://github.com/jnicklas/capybara.git’
    gem ‘launchy’
    gem ‘database_cleaner’

  • added/modified what seems like alot of requires to spec_helper.rb
    (spork, rubygems, rspec/rails, capybara/rspec, capybara/rails,
    database_cleaner).

  • changed some of my matchers from, what I think came from, webrat to,
    what I think works with, Capybara…but I’m getting failures in my
    controller & view specs. I’d really love to understand WHY and HOW/
    WHERE to look so in the future I can diagnose these errors myself.

VIEW SPEC:

spec/view/pages/about.html.haml_spec.rb

require ‘spec_helper’

describe “pages/about.html.haml” do
it “should have the right heading” do

render # <- worked with webrat

rendered.should have_selector(“h2”, :content => “About Us”)

visit pages_about_path
page.should have_selector(‘h2’)
end
end

Failures:

pages/about.html.haml should have the right heading
Failure/Error: visit pages_about_path
NoMethodError:
undefined method `visit’ for
#RSpec::Core::ExampleGroup::Nested_7:0x0000010320a568

CONTROLLER SPEC:

spec/controllers/pages_controller_spec.rb

require ‘spec_helper’

describe PagesController do

describe “GET ‘about’” do
it “should be successful” do
# get ‘about’ # <- worked with webrat
# response.should be_success # <- webrat ok
visit pages_about_path
# visit ‘/pages/about.html’ # <- also fails w/capybara
page.should have_content(‘About Us’)
# page.html.should match(/About/i) # no help
# page.should match(/About/i) # no help
end
end

Failures:

  1. PagesController GET ‘about’ should be successful
    Failure/Error: visit pages_about_path
    LoadError:
    no such file to load – action_controller/integration

    ./spec/controllers/pages_controller_spec.rb:10:in `block (3

levels) in <top (required)>’

I’d move haml and sass out of these groups - you need them in
production.

gem ‘spork’, ‘~> 0.9.0.rc’
end

group :test do
gem ‘rspec’
end

Don’t need ^^ this because rspec-rails already depends on rspec (so it’s
already installed).

gem ‘capybara’, :git => ‘git://github.com/jnicklas/capybara.git’
Strongly recommend sticking to releases while you’re getting your feet
wet.

gem ‘capybara’, ‘1.0.0.beta1’

Otherwise everytime you update the bundle you’ll get a different
revision.

WHERE to look so in the future I can diagnose these errors myself.
visit pages_about_path
page.should have_selector(‘h2’)

visit and page are not available in view specs. Stick with render and
rendered. If you’re using Capybara-1.0.0.beta1 you can use the
have_selector method in the view spec.

 # response.should be_success   #  <- webrat ok
  1. PagesController GET ‘about’ should be successful
    Failure/Error: visit pages_about_path
    LoadError:
    no such file to load – action_controller/integration

    ./spec/controllers/pages_controller_spec.rb:10:in `block (3

levels) in <top (required)>’

Not sure about this part. Looks like it thinks its an integration test
(which it is not - it’s an ActionController::TestCase).

HTH,
