Finishing Recipe Details

‹prev | My Chain | next›

Working my way back out to the features, I hit a snag. The main application spec exercises the new wiki helper method with nil input. The result is an error. I need to describe how the helper should work in such a situation:

  it "should return an empty string if called with nil" do
    wiki(nil).should == ""
  end

Making this example pass is a simple matter of using an empty string if nil is supplied to the wiki helper:

    def wiki(original)
      text = (original || '').dup
      text.gsub!(/\b(\d+)F/, "\\1° F")
      text.gsub!(/\[kid:(\w+)\]/m) { |kid| kid_nicknames[$1] }
      text.gsub!(/\[recipe:(\S+)\]/m) { |r| recipe_link($1) }
      RedCloth.new(text).to_html
    end

Back Out to the Feature

Running the feature that started this helper effort reveals that I need to check off two more steps in the scenario:

cstrom@jaynestown:~/repos/eee-code$ cucumber features/recipe_details.feature \
    -n -s "Viewing summary and recipe instructions"
Feature: Recipe Details

  So that I can accurately reproduce a recipe at home
  As a web user
  I want to be able to easily recognize important details
  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


1 scenario
2 steps passed
2 steps pending (2 with no step definition)

You can use these snippets to implement pending steps which have no step definition:

Then /^I should a nice summary of the dish$/ do
end

Then /^I should see detailed, easy\-to\-read instructions$/ do
end

Those pending steps can be implemented with matchers similar to:

Then /^I should a nice summary of the dish$/ do
  response.should have_selector("p", :content => "This dish is yummy") do |p|
    p.should have_selector("strong", :content => "yummy")
  end
end

Then /^I should see detailed, easy\-to\-read instructions$/ do
  response.should have_selector("p", :content => "While the shrimp are defrosting, we chop the vegetables.")
end
