        """Creates a test client for this application.  For information
        about unit testing head over to :ref:`testing`.

        The test client can be used in a `with` block to defer the closing down
        of the context until the end of the `with` block.  This is useful if
        you want to access the context locals for testing::

            with app.test_client() as c:
                rv = c.get('/?vodka=42')
                assert request.args['vodka'] == '42'

        .. versionchanged:: 0.4
           added support for `with` block usage for the client.
