java—如何模拟hadoop文件系统

我试图用powermock和mockito来模拟hadoop文件系统和构造函数。我对Mockito斯还不熟悉，所以我不确定到底出了什么问题。

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

     public class TestHadoopTest {

    @Test
    public void testtestme() throws Exception {

        CopyBookReader cbr = PowerMockito.mock(CopyBookReader.class);
        TestHadoop testhad = new TestHadoop();          
        PowerMockito.mockStatic(FileSystem.class);
        Configuration conf = mock(Configuration.class);

        PowerMockito.whenNew(CopyBookReader.class).withArguments(isA(Path.class),isA(FileSystem.class)).thenReturn(cbr);
        testhad.testme();

    }

}

public class TestHadoop {

    public void testme() throws Exception{

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

}
