Question

我有一个处理ftp服务器的应用程序，现在我想写一些测试，但是我在开始时遇到了麻烦，我试图模拟会话工厂但它抛出异常并且无法理解为什么，这是我的代码：

@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));
}

这是我得到的例外：

有人能告诉我哪里做错了吗？：/

如果您要测试您的FtpClient，您可以使用MockFtpServer在测试中配置和使用非常简单。

MockFtpServer项目提供模拟/虚拟FTP服务器对FTP客户端测试非常有用的实现码。提供了两个FTP服务器实现，每个实现不同抽象程度。

Java模拟FTP会话
