This module may be used in unit tests, for when you want to test that your SSH state machines are really doing what you expect they are doing. You will typically include this module in your unit test class, and then build a "story" of expected sends and receives:

  require 'test/unit'
  require 'net/ssh/test'

  class MyTest < Test::Unit::TestCase
    include Net::SSH::Test

    def test_exec_via_channel_works
      story do |session|
        channel = session.opens_channel
        channel.sends_exec "ls"
        channel.gets_data "result of ls"
        channel.gets_close
        channel.sends_close
      end

      assert_scripted do
        result = nil

        connection.open_channel do |ch|
          ch.exec("ls") do |success|
            ch.on_data { |c, data| result = data }
            ch.on_close { |c| c.close }
          end
        end

        connection.loop
        assert_equal "result of ls", result
      end
    end
  end

See Net::SSH::Test::Channel and Net::SSH::Test::Script for more options.

Note that the Net::SSH::Test system is rather finicky yet, and can be kind of frustrating to get working. Any suggestions for improvement will be welcome!

Public Instance methods

First asserts that a story has been described (see story). Then yields, and then asserts that all items described in the script have been processed. Typically, this is called immediately after a story has been built, and the SSH commands being tested are then executed within the block passed to this assertion.

Returns the connection session (Net::SSH::Connection::Session) for use in these tests. It is a fully functional SSH session, operating over a mock socket (socket).

Returns the test socket instance to use for these tests (see Net::SSH::Test::Socket).

If a block is given, yields the script for the test socket (socket). Otherwise, simply returns the socket‘s script. See Net::SSH::Test::Script.

Returns the transport session (Net::SSH::Transport::Session) for use in these tests. It is a fully functional SSH transport session, operating over a mock socket (socket).
