### Question:
FSToFSTransferClient implements BinaryTransferClient { @Override public BinaryDetails getStoredBinaryDetails(PID binPid) { return FileSystemTransferHelpers.getStoredBinaryDetails(destination, binPid); } FSToFSTransferClient(IngestSource source, StorageLocation destination); @Override URI transfer(PID binPid, URI sourceFileUri); @Override URI transferReplaceExisting(PID binPid, URI sourceFileUri); URI transfer(PID binPid, URI sourceFileUri, boolean allowOverwrite); @Override URI transferVersion(PID binPid, URI sourceFileUri); @Override void shutdown(); @Override boolean isTransferred(PID binPid, URI sourceUri); @Override BinaryDetails getStoredBinaryDetails(PID binPid);  }### Answer:
@Test public void getStoredBinaryDetailsForAbsentFile() { assertNull(client.getStoredBinaryDetails(binPid)); }
