お隣のプログラマがとっても幸せそうだったのでチェック！

rspecとrspec-railsは入っているものとしています。

以下を入れます。

sudo gem install nokogiri
sudo gem install webrat
sudo gem install cucumber
sudo gem install term-ansicolor
sudo gem install treetop
sudo gem diff-lcs

テスト用のプロジェクトを作って確認します。

% rails -d mysql testhoge
% cd testhoge
% rake db:create:all
% ./script/generate cucumber
% ./script/generate rspec
% ./script/generate rspec_scaffold Post name:string content:text
% ./script/generate feature Post name:string content:text
% rake db:migrate

feature/以下にファイルができています。
manage_posts.featureとか。

とりあえず実行してみます。

% rake features
(in /home/works/code/rails/testhoge)
/opt/local/bin/ruby -I "/opt/local/lib/ruby/gems/1.8/gems/cucumber-0.3.0/lib:lib" "/opt/local/lib/ruby/gems/1.8/gems/cucumber-0.3.0/bin/cucumber" --format pretty --require features/step_definitions/post_steps.rb --require features/step_definitions/webrat_steps.rb --require features/support/env.rb --require features/support/paths.rb features/manage_posts.feature
Feature: Manage posts
  In order to [goal]
  [stakeholder]
  wants [behaviour]

  Scenario: Register new post                # features/manage_posts.feature:6
    Given I am on the new post page          # features/step_definitions/webrat_steps.rb:6
    When I fill in "Name" with "name 1"      # features/step_definitions/webrat_steps.rb:22
    And I fill in "Content" with "content 1" # features/step_definitions/webrat_steps.rb:22
    And I press "Create"                     # features/step_definitions/webrat_steps.rb:14
    Then I should see "name 1"               # features/step_definitions/webrat_steps.rb:93
    And I should see "content 1"             # features/step_definitions/webrat_steps.rb:93

  Scenario: Delete post                    # features/manage_posts.feature:14
    Given the following posts:             # features/step_definitions/post_steps.rb:1
      | name   | content   |
      | name 1 | content 1 |
      | name 2 | content 2 |
      | name 3 | content 3 |
      | name 4 | content 4 |
    When I delete the 3rd post             # features/step_definitions/post_steps.rb:5
    Then I should see the following posts: # features/step_definitions/post_steps.rb:12
      | name   | content   |
      | name 1 | content 1 |
      | name 2 | content 2 |
      | name 4 | content 4 |

2 scenarios
9 passed steps

Given~とかWhen~とかは緑色になってました。

動く事を確認できました。

次回は、

• 出力結果を日本語
• feature自体を日本語で書く

ようにしてみたいと思います。
