ab-mrubyを使って自分のサイトを継続的にテストしてみた


最近良く聞く継続的なんとかを僕も試してみたくて、早速最近作ったabコマンドベースのベンチマークで、自由にRubyでベンチマークパターンやテストケースを書けるab-mrubyを使ってWebサーバの継続的なテストをしてみました。

ab-mrubyだとどのように書けるか書いてみたので紹介します。

まずはベンチマークパターン

自分のblogとmoblogとregisterunderflowに対するベンチマークパターンを以下のように記述しました。

$ cat ab-mruby.conf.rb
print <<EOS

end

それぞれ、SSLの指定や同時接続数などを微妙に変えています。

次にテストスイート

テストは以下のように書きました。大体これぐらいのクオリティは満たしておいて欲しいなぁという値をテストケースにいれました。

$ cat ab-mruby.test.rb
module Kernel
  def test_suite &blk
    @@r = get_config
    @@t = blk
    @@result = true
  end
  def bln_color val
    (val) ? "[¥e[33m#{val}¥e[m]" : "[¥e[36m#{val}¥e[m]"
  end
  def should_be val
    ret = @@r[self] == val
    puts "[TEST CASE] #{bln_color ret} #{self} (#{@@r[self]}) should be #{val}"
    @@result = ret if ret == false
  end
  def should_be_over val
    ret = @@r[self] > val
    puts "[TEST CASE] #{bln_color ret} #{self} (#{@@r[self]}) should be over #{val}"
    @@result = ret if ret == false
  end
  def should_be_under val
    ret = @@r[self] < val
    puts "[TEST CASE] #{bln_color ret} #{self} (#{@@r[self]}) should be under #{val}"
    @@result = ret if ret == false
  end
  def test_run
    @@t.call
    puts "¥ntest suites: #{bln_color @@result}¥n"
  end
end

あとは継続的にテスト

今回はシェルスクリプトで適当に書きました。

本当はRakefileみたいなの作って、あるディレクトリ以下にURL毎にディレクトリを作って、その中にそれぞれ上記のテストケースやベンチマークパターンをいれて、rake hogeとかした方がだいぶカッコいいと思いますが、僕の場合はこれで十分です。

$ cat ab-mruby-test.sh
#!/bin/sh

TARGET="
  http://blog.matsumoto-r.jp/
  http://moblog.matsumoto-r.jp/
  https://registerunderflow.org/
"


AB_MRUBY="./ab-mruby"
AB_MRUBY_CONFIG="./ab-mruby.conf.rb"
AB_MRUBY_TEST="./ab-mruby.test.rb"

for url in $TARGET
do
  $AB_MRUBY -m $AB_MRUBY_CONFIG -M $AB_MRUBY_TEST $url
done

そいてこれを実行すると、以下のようにテスト結果が出力されました。

あっあっ、なんだかblogの処理性能が少し落ちてテストがコケていますね。アクセス集中でもしていたのでしょうか。でもこれで簡単かつ継続的にWebサーバの品質をabコマンドベースのベンチマークで確認できますね。

最後に

このように、abコマンドベースで自由にベンチマークパターンやテストケースを書けるab-mrubyを自分のサイトで継続的になんとかしてみました。

こんな風に簡単にかけてしまうとやはり楽しいものですね。
