spec_helper.rbにテスト対象のホストの情報を登録する。登録する情報は以下の通り。
さらに、テストスクリプトに記載された順番通りにテストが実施されるように記載する。

作成したテストスクリプトは以下となる。各処理のTIPSは後ほど、機能ごとに説明する。

以下のコマンドでInfrataster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。パラメータに実行するテストスクリプトファイルを指定した場合、そのファイルのみのテストが実行される。指定がない場合、specフォルダ以下の全テストスクリプトファイル(*_spec.rb)が順次実行される。
$ /usr/local/bin/rspec -f d spec/tissvv096_spec.rb | tee tissvv096_test.log
'-f'オプションはログ出力の形式を定義している。使用できるオプションはrspec --helpで表示される。
-f, --format FORMATTER Choose a formatter. [p]rogress (default - dots) [d]ocumentation (group and example names) [h]tml [j]son custom formatter class name
今回はエビデンスとして利用するため、'-f d'を使用している。
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。
