の起動中に、私は

Junit -4 
selenium-java-2.42.2 
selenium-server-standalone-2.21.0 
& Firefox Setup 42.0 

を使用しかし、あなたはFF 39.0以上を実行したい場合は、まだそのエラーに

Answer 1

を取得しますプロジェクトにセレン-2.4.0のjarファイルを追加します。 FF 47.0以上の場合は、セレン-2.53.0ジャンパーをマリネットと共に使用してください。

まず、hello worldプログラムを実行していれば、同じ組み合わせで実際のプログラムを実行すると、selenium-2.43.0、FF 42.0、JUnit（少なくとも1つのテストアノテーション）の組み合わせで実行できます。
