テストの実行中にエラーが発生しました。私はSQLIntegrityConstraintViolationExceptionを取得します。一意キーまたは主キー制約でキー値が重複したためにステートメントが中止されました
Internal Exception: java.sql.SQLIntegrityConstraintViolationException: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'SQL160412141534310' defined on 'CHARACTERS'.
