Feature #220
Updated by kevincolemaninc (kevin coleman) about 8 years ago
=begin 遠藤です。 Ruby 本体にカバレッジ測定機能を提供するのはどうでしょうか。 具体的には、ソースごとの各行の実行回数を表す定数 COVERAGE__ を 導入したいです。SCRIPT_LINES__ のカバレッジ版のようなイメージです。 1. ユーザが COVERAGE__ に {} を設定する 2. ユーザがソースファイルを require や load する 3. COVERAGE__[ファイル名] が各行の実行回数を表す配列を返すようになる (この配列は実行に従って勝手に更新される) ※ COVERAGE__ が設定されなければ何もしません。 ※ 空行など実行される可能性がない行は nil になります。 ※ eval は測定対象にしません。 動作の具体例です。 $ cat foo.rb s = 0 10.times do |x| s += x end if s == 45 p :ok else p :ng end $ ./ruby -e 'COVERAGE__ = {}; require "foo.rb"; p COVERAGE__' :ok {"/home/mame/work/ruby19/ruby/foo.rb"=>[1, 1, 10, nil, nil, 1, 1, nil, 0, nil]} この配列は各行の実行回数を表しています。 上記の仕様を実装したものを添付します。 サンプルとして、lib/coverage.rb を同梱しています。 以下のように使えます。 $ ./ruby -rcoverage foo.rb $ cat foo.rb.cov 1: 0:s = 0 1: 1:10.times do |x| 10: 2: s += x -: 3:end -: 4: 1: 5:if s == 45 1: 6: p :ok -: 7:else #####: 8: p :ng -: 9:end また、RUNRUBYOPT="-rcoverage" make test-all した結果を集計して みました。バグとかで不正確な結果になってる可能性はありますが、 このくらいは動くと言うことで。 $ ./ruby -e ' aan = acn = 0 Dir["{lib,.ext}/**/*.cov"].each do |f| an, cn = File.readlines(f).inject([0, 0]) do |(an, cn), l| next [an, cn] if l.start_with?(" -") an += 1 cn += 1 if !l.start_with?(" #####") [an, cn] end puts "%s %.2f%% (%d/%d)" % [f, cn.to_f * 100 / an, cn, an] aan += an acn += cn end puts "(total) %.2f%% (%d/%d)" % [acn.to_f * 100 / aan, acn, aan] ' lib/drb/unix.rb.cov 86.11% (62/72) lib/drb/drb.rb.cov 81.70% (491/601) lib/drb/eq.rb.cov 100.00%
