テストスクリプトの実行

1.テストスクリプトの実行

　以下のコマンドでServerspecのテストスクリプトが実行される。結果は標準出力に出力されるため、teeコマンドを利用し、ファイルにも保存している。

単一ホストを実行したい場合

$ rake spec：tissvv096 | tee tissvv096_test.log

全ホストを実行したい場合

$ rake spec | tee all_host_test.log

　実行時のディレクトリのローカルに存在するRakefileを参照し、実行対象のテストスクリプトが選択、実行される。デフォルトで生成されるRakefileは以下の通り。上記コマンドの例のように、spec:[ホスト名]と指定すると、単一ホストのみが実行される。省略した場合は、./spec直下のホスト名を抽出し、1ホストごとに順番にテストスクリプトを実行するようになっている。

require 'rake'
require 'rspec/core/rake_task'
task :spec    => 'spec:all'
task :default => :spec
namespace :spec do
  targets = []
  Dir.glob('./spec/*').each do |dir|
    next unless File.directory?(dir)
    target = File.basename(dir)
    target = "_#{target}" if target == "default"
    targets << target
  end
  task :all     => targets
  task :default => :all
  targets.each do |target|
    original_target = target == "_default" ? target[1..-1] : target
    desc "Run Serverspec tests to #{original_target}"
    RSpec::Core::RakeTask.new(target.to_sym) do |t|
      ENV['TARGET_HOST'] = original_target
      t.pattern = "spec/#{original_target}/*_spec.rb"
    end
  end
end

2.ログ出力

　テストスクリプトの実行により、以下の結果が出力される。
