Join For Freein continuation of my earlier blog spring integration fakeftpserver example in this example i will show how to test spring integration flow using mock sftpserver. there a are few good writeups on the net including the stackoverflow writeup, using apache mina as a mock/in memory sftp server for unit testing. the code for this blog is @ spring integration flow to test ftp/sftp server .
to run the junit test, run “mvn test” and understand the test flow.
again talking about the same spring integration flows as mentioned in my earlier blog, i will write a test for a sftp server,
the maven dependency for this is as below,
<dependency>
<groupid>org.apache.sshd</groupid>
<artifactid>sshd-core</artifactid>
<version>0.5.0</version>
</dependency>
<dependency>
<groupid>org.slf4j</groupid>
<artifactid>slf4j-api</artifactid>
<version>1.6.1</version>
</dependency>
<dependency>
<groupid>com.jcraft</groupid>
<artifactid>jsch</artifactid>
<version>0.1.49</version>
</dependency>
<dependency>
<groupid>org.slf4j</groupid>
<artifactid>slf4j-log4j12</artifactid>
<version>1.7.2</version>
</dependency>
the startup and teardown of the junit is as below,
@before
public void beforetestsetup() throws exception {
sshd = sshserver.setupdefaultserver();
sshd.setport(22999);
sshd.setkeypairprovider(new simplegeneratorhostkeyprovider("hostkey.ser"));
sshd.setpasswordauthenticator(new passwordauthenticator() {
public boolean authenticate(string username, string password, serversession session) {
// todo auto-generated method stub
return true;
}
});
commandfactory mycommandfactory = new commandfactory() {
public command createcommand(string command) {
system.out.println("command: " + command);
return null;
}
};
sshd.setcommandfactory(new scpcommandfactory(mycommandfactory));
list<namedfactory<command>> namedfactorylist = new arraylist<namedfactory<command>>(); namedfactorylist.add(new sftpsubsystem.factory()); sshd.setsubsystemfactories(namedfactorylist); sshd.start(); }
@after
public void teardown() throws exception { sshd.stop(); }
the junit test is as below,
public void testputandgetfile() throws exception {
jsch jsch = new jsch();
hashtable config = new hashtable();
config.put("stricthostkeychecking", "no");
jsch.setconfig(config);
session session = jsch.getsession("remote-username", "localhost", 22999);
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);
asserttrue(downloadedfile.exists());
string filedata = getfilecontents(downloadedfile);
assertequals(testfilecontents, filedata);
if (sftpchannel.isconnected()) {
sftpchannel.exit();
logger.debug("disconnected channel");
}
if (session.isconnected()) {
session.disconnect();
logger.debug("disconnected session");
}
}
i hope this blog helped you.
