使用Apache Mina作为模拟/内存SFTP服务器进行单元测试

Question

我在处理如何使用Apache Mina时遇到了一些麻烦。他们的文档对于我的无能的大脑来说是有点缺乏的。我看到有用的起始代码在 Java SFTP server library?

我无法弄清楚的是如何使用它。我想设置一个单元测试，检查我的SFTP代码，使用米娜作为一种模拟服务器，即，能够编写单元测试，如：

@Before 
public void beforeTestSetup() { 
    sshd = SshServer.setUpDefaultServer(); 
    sshd.setPort(22); 
    sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("hostkey.ser")); 

    List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<NamedFactory<UserAuth>>(); 
    userAuthFactories.add(new UserAuthNone.Factory()); 
    sshd.setUserAuthFactories(userAuthFactories); 
    sshd.setPublickeyAuthenticator(new PublickeyAuthenticator()); 


    sshd.setCommandFactory(new ScpCommandFactory()); 

    List<NamedFactory<Command>> namedFactoryList = new ArrayList<NamedFactory<Command>>(); 
    namedFactoryList.add(new SftpSubsystem.Factory()); 
    sshd.setSubsystemFactories(namedFactoryList); 

    try { 
     sshd.start(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

@Test 
public void testGetFile() { 

} 

的问题是要放什么testGetFile()。

我一直在测试通过测试代码，想知道在上面是否需要更多的配置来指定根目录，用户名和认证密钥文件名。那么我需要使用客户端或我自己的SFTP API代码来从中获取文件？

我确定这是一个很好的API，没有太多的指导，任何人都可以帮忙吗？

这里是我做的测试（JUnit）：

@Test 
    public void testPutAndGetFile() throws JSchException, SftpException, IOException 
    { 
    JSch jsch = new JSch(); 

    Hashtable<String, String> config = new Hashtable<String, String>(); 
    config.put("StrictHostKeyChecking", "no"); 
    JSch.setConfig(config); 

    Session session = jsch.getSession("remote-username", "localhost", PORT); 
    session.setPassword("remote-password"); 

    session.connect(); 

    Channel channel = session.openChannel("sftp"); 
    channel.connect(); 

    ChannelSftp sftpChannel = (ChannelSftp) channel; 

    final String testFileContents = "some file contents"; 

    String uploadedFileName = "uploadFile"; 
    sftpChannel.put(new ByteArrayInputStream(testFileContents.getBytes()), uploadedFileName); 

    String downloadedFileName = "downLoadFile"; 
    sftpChannel.get(uploadedFileName, downloadedFileName); 

    File downloadedFile = new File(downloadedFileName); 
    Assert.assertTrue(downloadedFile.exists()); 

    String fileData = getFileContents(downloadedFile); 

    Assert.assertEquals(testFileContents, fileData); 

    if (sftpChannel.isConnected()) { 
     sftpChannel.exit(); 
     System.out.println("Disconnected channel"); 
    } 

    if (session.isConnected()) { 
     session.disconnect(); 
     System.out.println("Disconnected session"); 
    } 

    } 

    private String getFileContents(File downloadedFile) 
    throws FileNotFoundException, IOException 
    { 
    StringBuffer fileData = new StringBuffer(); 
    BufferedReader reader = new BufferedReader(new FileReader(downloadedFile)); 

    try { 
     char[] buf = new char[1024]; 
     for(int numRead = 0; (numRead = reader.read(buf)) != -1; buf = new char[1024]) { 
     fileData.append(String.valueOf(buf, 0, numRead)); 
     } 
    } finally {  
     reader.close(); 
    } 

    return fileData.toString(); 
    }
