ruby on rails プロジェクト [1] で多くの rake テストが失敗し、すべて同じエラー (nil を String に変換できない) があり、なぜこれが起こっているのか、どのようにデバッグすればよいのかわかりません。 .

たとえば、これは rake テストの最初のトレースバックです (メッセージの最後に完全な rake テストのトレースバックを添付しました [2])。

そして、合計1448回のテストのエラーを含む200回以上のテストがあります。

問題は、どこからデバッグを開始する必要があるかということです。+90% のテストで同じエラーが発生するのはなぜですか?

デバッグの場合。gem 'pry-rails' の使用をお勧めします。この gem をバンドルして、失敗したテストに「binding.pry」を追加するだけです。テストのすべての変数でコンソールが開くので、手動で確認できます。何が問題なのかを知るのに役立つことを願っています。

Cucumber バージョンの問題の 1 つかもしれません。

これは、cucumber-rails を最新バージョンにアップグレードすることで修正できます。これを表示するには、Gemfile を編集するだけです。

gem 'cucumber-rails', '>= 1.1.1'または新しいバージョン

私が同じを得たとき、それは私のエラーを解決しました。

あなたの場合、その指摘delayed_job gem

使用している場合はbundler、スクリプトまたは rake タスクの前に " bundle exec"を付けてみてください。

bundle exec script/delayed_job -n 2 start

そして試してみてください!!!!
