import jcifs.smb.SmbFile;

// Using default context
CIFSContext context = SingletonContext.getInstance();

// Access a file (encryption is transparent - automatically used if server requires it)

                    }
                }
            }

    }

    @Test

        // Mocking SmbFile constructor is tricky, so we'll just verify the call to the delegate
        // and ensure no exception is thrown for a valid URL.
        // The actual SmbFile creation is outside the scope of this wrapper's direct responsibility.
