特定の製品 (to-do リスト) の GUI (JavaFX) をテストするために、TestFX を使用して以下の JUnit4 テストを作成し、必要な 2 つのクラスを作成しました。最初のクラスは GUI 全体を管理するメイン クラスで、2 番目はテキスト フィールドのクラスです。完全なソース コードは、必要に応じてここにあります(すでに提出されている学校のプロジェクトの一部でした)。
Eclipse で F11 ホットキー、または「Run As -> JUnit Test」を使用してテストを実行すると、テストは完全に正常に機能します。ただし、「カバレッジ」を選択すると、最初のテストケースにバグが発生します（最初に設定したものに関係なく）。具体的には、最初のテスト ケースの最初の 2 文字 (ここのサンプル ケースでは sh) を「入力」し、ユーザー入力が検出されたというエラーを表示します ( [TestFX] User mouse movement detected. Aborting test.)。その後、次のテスト ケースに移動します。
私は自分でそれを理解することができず、これについてオンラインで多くの助けを見つけることができないようです. どんな援助でも大歓迎です！スタック トレースに基づいて、それはスレッドに関するものであるように見えますが、実行中のカバレッジがどのようにそれを引き起こすのかわかりません (通常のテストでは発生しない場合)。
制限に達したため、スタック トレースを短くする必要がありました。
