 * objectIdは、{@link Message}に設定するオブジェクトを指定するもので、同一テストケース中に、このTestActionより前に、オブジェクトを戻すテストアクションが存在する場合は、そのアクションIDを指定する。また、同一シナリオ中に、このTestActionより前に、オブジェクトを戻すテストアクションが存在する場合は、テストケースIDとアクションIDをカンマ区切りで指定する。空行を指定した場合は、オブジェクトをTestActionの結果から取得しない。<br>
 * objectScriptは、{@link Message}に設定するオブジェクトを生成するスクリプトを指定する。スクリプトは、{@link Interpreter#evaluate(String,Map)}で評価され、引数の変数マップには、"context"で{@link TestContext}、"preResult"でpreResultが渡される。<br>
 * objectId、objectScriptの両方が指定されていない場合は、preResultを使用する。<br>
