Two Steps Back

‹prev | My Chain | next›

First up in chain #2 is getting back (as close as possible) to where chain #1 left off. I am going to develop on my Lenovo s10-s netbook, so the first order of business becomes running my specs on a relatively new install Ubuntu 9.10.

I have already done some development on this netbook, so I do not have to install Ruby from scratch along with a bunch of gems. I also have CouchDB installed via apt-get (reported as 0.10.0-0ubuntu3).

So I run my specs, only to find a bunch of these:

...
64)
Haml::SyntaxError in 'recipe.haml a recipe without an image should not include an image'
Unbalanced brackets.
(haml):52:
/home/cstrom/repos/eee-code/spec/spec_helper.rb:26:in `new'
/home/cstrom/repos/eee-code/spec/spec_helper.rb:26:in `render'
./spec/views/recipe.haml_spec.rb:360:

Bah! Did Haml remove my favorite feature of splitting attributes across lines à la:

          %img{:src => "/images/amazon-126X32-w-logo.gif",
               :border => 0}

No, Haml still has this, just not in the version in Karmic (2.0.9-1). After a quick apt-get remove and gem install haml, my view specs all pass.

The last obstacle to passing specs are my app specs which reveal an oversight on my part. One of the outputs from chain #1 was the couch_docs gem. It was originally named couch_design_docs, but got a rename after its capabilities increased. The rename did not make it into my spec helpers (they use it to load fixtures and design documents). A quick search and replace and all of my unit tests are passing:

cstrom@whitefall:~/repos/eee-code$ rake
(in /home/cstrom/repos/eee-code)

With unit tests passing, it is time to have a look at the Cucumber integration tests. Sadly, the view ain't pretty:

cstrom@whitefall:~/repos/eee-code$ cucumber features/site.feature

My fresh install of Cucumber onto this netbook is a more recent version than I used to originally develop the application. After consulting the Cucumber / Sinatra documentation, I find that I need to change:

 Webrat.configure do |config|
  config.mode = :sinatra
 end
 
World do
  session = Webrat::SinatraSession.new
  session.extend(Webrat::Matchers)
  session.extend(Webrat::HaveTagMatcher)
  session
end

To:

 Webrat.configure do |config|
  config.mode = :rack
 end

class MyWorld
  include Rack::Test::Methods
  include Webrat::Methods
  include Webrat::Matchers

  Webrat::Methods.delegate_to_session :response_code, :response_body

  def app
    Sinatra::Application
  end
 end
 
World{MyWorld.new}

Simply put, I need to use rack to test now and alter the "world" (session) a bit. With that, I get:

cstrom@whitefall:~/repos/eee-code$ cucumber features/site.feature

    And the Vegetarian category should be highlighted                        # features/step_definitions/site.rb:121

While this might not seem like progress, I am now failing where I want to—CouchDB it generating 500 failures because my views stink. I'll start fixing them tomorrow.
