### Question:
ZipEntryInputStream extends InputStream { @Override public void mark(int readlimit) { zipInputStream.mark(readlimit); } ZipEntryInputStream(ZipInputStream zipInputStream); @Override int available(); @Override void close(); @Override void mark(int readlimit); @Override boolean markSupported(); @Override int read(); @Override int read(byte[] b); @Override int read(byte[] b, int off, int len); @Override void reset(); @Override long skip(long n);  }### Answer:
@Test public void markShouldDelegateToZipInputStreamMark() { zipEntryInputStream.mark(7); Mockito.verify(zipInputStream, Mockito.times(1)).mark(7); Mockito.verifyNoMoreInteractions(zipInputStream); }
