Expect sending string twice

[prati...@gmail.com]

Code::
JSch jSch = new JSch();
Session session = jSch.getSession("admin", "192.168.0.233");
session.setPassword("vnera123");
session.setConfig("StrictHostKeyChecking", "no");
session.connect();
Channel channel = session.openChannel("shell");

Expect expect = new ExpectBuilder()
.withOutput(channel.getOutputStream())
.withInputs(channel.getInputStream(), channel.getExtInputStream())
.withEchoOutput(adapt(System.out))
.withInputFilters(removeColors(), removeNonPrintable())
.withErrorOnTimeout(true)
.build();
channel.connect();
expect.expect(contains("R1>"));
expect.sendLine();
expect.sendLine("enable");
expect.expect(contains("Password: "));
expect.sendLine("abcde");
channel.disconnect();
session.disconnect();
expect.close();

Output:
1>
enable

R1>
R1>enable
Password:
% Access denied

R1>abcde
---------------------------------------------------------------------
The "enable" command and also the password seems to be sent twice.
Is this a bug or am I going wrong somewhere.
I am using the latest jar(expectit-core-0.3.1.jar).

Thank-You,
Pratik

Hi,

Hmm. In many other tests all the commands are clearly sent once. Perhaps your service echos the received command. 

To check that I suggest to separate the output of what was actually being sent from what was received. For example,  when constructing an Expect instance you can pass the following sample anonymous EchoOutput class:

==========

          .withEchoOutput(new EchoOutput() {

                    @Override

                    public void onReceive(int input, String string) throws IOException {

                        System.out.println("RECEIVE:" + string);

                    }

                    @Override

                    public void onSend(String string) throws IOException {

                        System.out.println("SEND:" + string);

                    }

                })

============

Then that can give a clue of what was sent and what was received.

Regards,

Alexey

It would be nice to update this debugging tip using the new input and output methods (withEchoOutput/withEchoInput)

Best regards,
Sebastian

Done.

Ok thanks.
Hoy sould it work now to only capture the received data? compared to the prevues method:

  .withEchoOutput(new EchoOutput() {

                    @Override

                    public void onSend(String string) throws IOException {

                        System.out.println("SEND:" + string);

                    }

                })

Hi!

Now you register an appender separately for input and output data. For example:

    …

    .withEchoOutput(System.out)

    .withEchoInput(System.err, …)

    …

The number of input appenders should correspond to the number of input streams.

The method accepts an instance of Appendable which quite flexible. You can pass a StringBuilder for example.

Alexey
