### Question:
ConnectionProgressStatus { public static ConnectionProgressStatus instanceForSend(final long byteCount) { return new ConnectionProgressStatus(CallbackType.SEND_PROGRESS, byteCount); } private  ConnectionProgressStatus(final CallbackType callbackType, final long byteCount); long getByteCount(); CallbackType getCallbackType(); static ConnectionProgressStatus instanceForSend(final long byteCount); static ConnectionProgressStatus instanceForReceive(final long byteCount); @Override String toString();  }### Answer:
@Test public void testInstanceForSend() { ConnectionProgressStatus status = ConnectionProgressStatus.instanceForSend(10); Assert.assertEquals("byte count not sent", 10, status.getByteCount()); }
