Java Mocking FTP Session

I have an application that deals with ftp server, now I want to write some test, but I got trouble in the beginning, I am trying to mock the session factory but it throws exception and could not understand why, here is my code:

@Mock
SessionFactory<FTPFile> sessionFactory;


@Before
public void initMocks() {
    MockitoAnnotations.initMocks(this);
    DefaultFtpSessionFactory sf = new DefaultFtpSessionFactory();
    sf.setHost(host);
    sf.setPort(port);
    sf.setUsername(username);
    sf.setPassword(password);
    Mockito.when(sessionFactory.getSession()).thenReturn((Session<FTPFile>) new CachingSessionFactory<FTPFile>(sf));
}

and here is the exception I got:

java.lang.IllegalArgumentException: [Assertion failed] - this String argument must have text; it must not be null, empty, or blank

If you are looking to test your FtpClient you could use MockFtpServer is very simple to configure and use in tests.

The MockFtpServer project provides mock/dummy FTP server implementations that can be very useful for testing of FTP client code. Two FTP Server implementations are provided, each at a different level of abstraction.
