selenium - Nunit 3 Console Runner を使用した Specflow テスト

Question

私は最近新しいプロジェクトを開始し、Specflow 2.1 を使用することにしました。これには NUnit3 が同梱されています。

現在、プロジェクトはセットアップされ、Visual Studio のテストランナーは正しく実行されていますが、Nunit 3 コンソールランナーから同じテストを実行しようとすると、エラーが発生します。

私が使用するコマンドは nunit3-console.exe --labels=All --framework=net-4.5 Blah.Testing.Specflow.dll

同じアセンブリを使用して 2 つのネイティブ Nunit テストを追加しましたが、それらは正常に実行されています。失敗している 1 つの specflow テストです。

TechTalk.Specflow アセンブリを反映して CreateTestRunnerInstance メソッドを調べてみましたが、解決策を導くのに役立つものは何も見つかりませんでした。
