Ruby on Rails Tutorial (12)
Gitlab 4.1 導入を、と思っていたのですが、導入予定の仮想リソースに不具合があるらしく提供元に問合せ中でレスポンスがすぐではないと見込んで続きに着手。
8.3 Introduction to Cucumber (optional)
BDD なツールとのこと。とりあえず先に進みます。
8.3.1 Installation and setup
Gemfile の test なナニに以下のように指定せよ、とのこと。
gem 'cucumber-rails', '1.2.1', :require => false gem 'database_cleaner', '0.7.0'
これは一旦、これまでのソレな commit を作っておいた方が良いな。あ、8.4 で全部まるっとヤッてしまってるみたい、ですがやっぱ commit は作ろう。
上を盛り込む前に以下。
$ git commit -a -m 'Chapter 8 Sign in, sign out'
で、盛り込み再開。
とりあえず Gemfile 更新したら以下。
$ bundle install
で、以下を、とありますね。で、それが済んだら以下らしい。
$ rails generate cucumber:install
create config/cucumber.yml
create script/cucumber
chmod script/cucumber
create features/step_definitions
create features/support
create features/support/env.rb
exist lib/tasks
create lib/tasks/cucumber.rake
gsub config/database.yml
gsub config/database.yml
force config/database.yml
8.3.2 Features and steps
あら、どっかで見たと思ったら cucumber てインフラ UT なソレで見たんだったな。とりあえずどんどん盛り込んでみます。
features/signing_in.feature が以下とのこと。
Feature: Signing in
Scenario: Unsuccessful signin
Given a user visits the signin page
When he submits invalid signin information
Then he should see an error message
Scenario: Successful signin
Given a user visits the signin page
And the user has an account
And the user submits valid signin information
Then he should see his profile page
And he should see a signout linkで、以下で試験実行なのかな。
$ bundle exec cucumber features/
あら、どうなったのかよく分からんぞ。なんとなくパスしてなさげ。features/step_definitions に以下な authentication_steps.rb を追加せよ、とあるのかどうか。
Given /^a user visits the signin page$/ do
visit signin_path
end
When /^he submits invalid signin information$/ do
click_button "Sign in"
end
Then /^he should see an error message$/ do
page.should have_selector('div.alert.alert-error')
end
Given /^the user has an account$/ do
@user = User.create(name: "Example User", email: "user@example.com",
password: "foobar", password_confirmation: "foobar")
end
When /^the user submits valid signin information$/ do
fill_in "Email", with: @user.email
fill_in "Password", with: @user.password
click_button "Sign in"
end
Then /^he should see his profile page$/ do
page.should have_selector('title', text: @user.name)
end
Then /^he should see a signout link$/ do
page.should have_link('Sign out', href: signout_path)
endで、実行してみると以下。
$ bundle exec cucumber features/
Using the default profile...
Rack::File headers parameter replaces cache_control after Rack 1.5.
