は私の効果的なポンポンは、この（非常に大きい:-(）のようになります。注目に値するかもしれない

何されます

Answer 1

JUnit JARが少なくともテストスコープの依存関係であることを確認してください。スタックトレースから、Tycoが確実に動作していることから問題が発生しているように見えます。 JUnit4TestCheckerのrunWithがヌルで、hereからロードされているため、NPEが発生しています。

私はTychoについて知識がありませんが、プロジェクトではなく、タイコプラグイン自体にJUnit依存関係を追加することもできます。

Answer 2

nullでない必要があるデータベース内にいくつかのエンティティがあるように見えますが、私が実行しようとしているテストは、Junit Plugin Testsです。 utはnullになります。 JUnitテストの実行中にこのメッセージが表示されますか？はいの場合、実際のコードでこのJunitで使用されるJunitテストとデータベースエンティティ/ SQLクエリを共有できますか？
