SporkからSpringに乗り換えた結果ｗｗｗｗｗｗｗｗｗｗｗｗ

Ruby on Rails

今までrspec + guard + sporkでやってきましたけど、sporkのテストにしか効かないあたりとかはイマイチだなぁ、と思ったので噂のSpringに乗り換えてみることにした。


Gemfile

group :development, :test do
  gem "rspec-rails", "~> 2.13.0"
  gem "guard-rspec", "~> 2.5.2"
~snip~
  gem 'spring'
end

$ bundle install
$ spring binstub rspec
$ spring rspec

エラった。
調べてみるとこのエラーはlisten gemが< 1.0のときに起きるらしい。
https://github.com/jonleighton/spring/issues/161

listen gemがなんの絡みで入ったのかわからないけど、とにかくupdateする。

$ bundle exec gem update listen
Updating installed gems
Updating listen
Successfully installed rb-inotify-0.9.0
Successfully installed rb-kqueue-0.2.0
Successfully installed listen-1.2.2
Gems updated: rb-inotify rb-kqueue listen

よし、と思ってリトライしたらまた同じエラーがでた。どうもguardのバージョンが低いと、低いlistenがインストールされちゃうみたいでguardもupdateしてやったらうまくいった。

リトライ

$ spring rspec
No DRb server is running. Running in local process instead ...
/usr/local/opt/rbenv/versions/2.0.0-p0/lib/ruby/gems/2.0.0/gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- spork (LoadError)

エラった。
spec/spec_helper.rbにsporkをrequireしているためだった。

それとSpork絡みの記述を削除してリトライ。

$ spring rspec
No DRb server is running. Running in local process instead ...

うまくいった。


guardと組み合わせてみる。guard-springというgemがある。
https://github.com/mknapik/guard-spring

Gemfile

group :development, :test do
  gem "rspec-rails", "~> 2.13.2"
  gem "guard-rspec", "~> 3.0.2"
  gem 'spring'
  gem 'guard-spring'
end

>||
$ bundle install
$ guard init spring
WARN: Unresolved specs during Gem::Specification.reset:
      thor (>= 0.14.6)
      ffi (>= 0.5.0)
      lumberjack (>= 1.0.2)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
20:49:44 - INFO - Guard here! It looks like your project has a Gemfile, yet you are running
20:49:45 - INFO - spring guard added to Guardfile, feel free to edit it

なんやらキモいワーニングがでた。複数バージョンのgemが入っているとこういうことになるらしい。bundle exec gem cleanupで掃除しよう。あと、この状態でもGuardfileにコンフィグが追記はされている。

追記されたコンフィグを消してリトライ。

$ bundle exec guard init spring
21:00:16 - INFO - spring guard added to Guardfile, feel free to edit it

うまくいったようだ。

Guradフィアルからは追加されたコンフィグ以外は全部消してしまった。

$ bundle exec guard 
21:32:02 - WARN - Failed to create all required binstubs
21:32:02 - INFO - Guard::Spring Initialized
21:32:02 - INFO - Guard uses Growl to send notifications.
21:32:02 - INFO - Guard uses TerminalTitle to send notifications.

21:32:02 - INFO - Stopping Spring
21:32:02 - INFO - Starting Spring
21:32:02 - INFO - Guard is now watching at '/Users/ria10/IdeaProjects/hoge-web'

ちゃんとファイルが変更されると動く。2回も動く。えっ。

spec_helper.rbから以下の記述を消さないとサービスでもう１回動いてしまうらしい。

require 'rspec/autorun'

手作業でテストを走らせる時も待たずに済む

$ spring rspec spec/routing/

はえぇ・・・。


よく使うrails console

$ spring rails c

これも２度めから爆速！


うーん。狙ったとおり、いまんとここっちのほうがいいかな。
