入門Jenkins 読書記録(1) - 世界のやまさ

前半の Android は後回しにして 7章の Rails を中心に読んだ。

Jenkins の環境は Ubuntu が中心だった。まずは OSX にというところで、 capybara-webkit をそのまま gem から入れようとしたらエラーとなった。Ruby はいろいろつまづきやすい。

capybara-webkit のインストールエラー

エラー内容

Installing capybara-webkit (0.14.2)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /Users/user/.rbenv/versions/1.9.3-p327/bin/ruby extconf.rb
Command 'qmake -spec macx-g++' not available


Gem files will remain installed in /Users/user/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/capybara-webkit-0.14.2 for inspection.
Results logged to /Users/user/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/capybara-webkit-0.14.2/./gem_make.out

An error occurred while installing capybara-webkit (0.14.2), and Bundler cannot
continue.
Make sure that `gem install capybara-webkit -v '0.14.2'` succeeds before
bundling.

対処

本書の説明で先に依存関係のあるQtを入れると書いてあったので、おそらくOSXも同様でしょうということで、以下コマンドを実行

brew install qt

無事 bundle install 出来た。

大量の DEPRECATION WARNING

いざ rake rspec を実行すると大量の DEPRECATION が出た。こんな内容

エラー内容

`include Capybara` is deprecated. Please use `include Capybara::DSL` instead.

DEPRECATION WARNING: The InstanceMethods module inside ActiveSupport::Concern will be no longer included automatically. Please define instance methods directly in RSpec::Rails::SetupAndTeardownAdapter instead. (called from <top (required)> at /Users/user/Documents/ruby/blog/spec/controllers/posts_controller_spec.rb:3)

Please define instance methods directly in RSpec::Rails::TestUnitAssertionAdapter instead.

対処

ぐぐってみるとどうやら rspec-rails のバージョンが古いからみたい。

gem 'rspec-rails', '~> 2.0' を単純に gem 'rspec-rails' にしたらとりあえずでなくなった

DatabaseCleaner のエラー

実行しても、 0 examples, 0 failures となっていてよく見ると以下エラーが出ていた。

エラー内容

Exception encountered: #<DatabaseCleaner::UnknownStrategySpecified: The 'trunsaction' strategy does not exist for the active_record ORM!  Available strategies: truncation, transaction, deletion>

対処

これは単純に typo で transaction にしてあげたらうまく実行できた。

実行して満足したので、今日はこの辺にしておく。
