UPDATE 20180209: Rails 5.1.4 の初期インストール (ミニテスト 5.11.3 を含む) に付属する新しいダミー アプリを作成し、テストは問題なく完了しました。世界で何がこの問題を引き起こしているのかを絞り込めないかどうかを確認するために、gemfile を使って実験を続けます...

アイデアやヒントがあれば教えてください！

最近、コードベースの新しい部分のテストを開始しましたが、非常に重大な問題を発見しました。何らかの理由で、すべてのテストでタイトルのエラーがスローされるようになりました。トレースを調べると、何らかの理由で引用された名前/テストのタイトルが問題を引き起こしているようです。パスしたことがわかっているテストに戻って実行すると(確かに以前の gem バージョンでは)、残念ながら、以下の User モデルで示すように、同じ結果が得られます。

RVM、Rails、Ruby を完全に削除して再インストールするなど、できることはすべて試しました。Minitest を 10.5.3 などの以前のビルドにバージョンアップしようとしましたが、まだうまくいきません。私はこれを修正するために一日のほとんどを費やしました。私は頭がいっぱいで、必死に助けが必要です! 私はすべてのgemを明示的にバージョン保護する必要があるという難しい方法を学びました;）

前もって感謝します！さらにファイル/スニペットを含める必要がある場合はお知らせください。スケジュールが許す限り、できれば 24 時間以内にご質問にお答えできるよう最善を尽くします。
