Wiki Specifcations

‹prev | My Chain | next›

Realizing that I had overlooked recipe summary and instructions, I get started on them tonight. The feature scenario:

    Scenario: Viewing summary and recipe instructions

      Given a recipe for Curried Shrimp
      When I view the recipe
      Then I should a nice summary of the dish
      And I should see detailed, easy-to-read instructions

The inside view specs are straight-forward:

  it "should display the recipe's summary" do
    self.stub!(:wiki).and_return("wiki #{@summary}")

    render("/views/recipe.haml")
    response.should have_selector("#eee-summary",
                                  :content => "wiki #{@summary}")
  end

  it "should display the recipe's instructions" do
    self.stub!(:wiki).and_return("wiki #{@instructions}")

    render("/views/recipe.haml")
    response.should have_selector("#eee-instructions",
                                  :content => "wiki #{@instructions}")
  end

The not-so-trivial part of working inside the guts of the application is that wiki helper method. In addition to textilizing text, it performs various domain-specific clean-up such as converting 250F to 250° F, replacing recipe URIs with linked titles and replacing our kids names with nicknames.

Happily, I spent quite a bit of time getting helpers into controller specs. Even better, that work makes direct helper specifications trivial:

require File.expand_path(File.dirname(__FILE__) + '/spec_helper' )

describe "wiki" do
  it "should return simple text as unaltered text" do
    wiki("bob").should == "bob"
  end
  it "should convert textile to HTML"
  it "should wikify temperatures"
  it "should wikify kids names"
  it "should wikify recipe URIs"
end

A trivial implementation of the wiki makes this spec pass:

    def wiki(text)
      text
    end

(commit)

Next up: making those other 4 examples pass.
