Как mock файловая система hadoop

Question

Я пытаюсь высмеять файловую систему hadoop и конструктор, используя power mock и mockito. Но я получаю следующую ошибку. Я новичок в mockitos, поэтому я не уверен, что не так.

>java.lang.VerifyError: Inconsistent stackmap frames at branch target 42

    FileStatus[] status = fs.listStatus (new Path ("string")); 
    CopyBookReader cBook = new CopyBookReader(status[0].getPath(),fs); 
    cBook.toString(); 
} 

}

Answer 1

Это вызвано ошибкой в ​​некоторых версиях Powermock как это противоречит Java 7 в модифицированном проверки байт-кода. Обновите свою версию Powermock.
