UnitTest
========

::

    from doctest import ELLIPSIS

    from shelldoctest.shellunittest import Connection, TestCase

    host = "localhost:22"

    class MyTest(TestCase):
        c1 = Connection(host)
        c2 = Connection(host)

        def test(self):
            self.assertOutput(self.c1, "pwd", "/.../...\n", ELLIPSIS)
            self.c1("cd /", None)
            self.assertOutput(self.c2, "pwd", "/.../...\n", ELLIPSIS)
            self.assertOutput(self.c1, "pwd", "/\n")
