        If you want to change cubicweb test server parameters, define a new

        :class:`CubicWebServerConfig` and override the :var:`configcls`

        attribute:

            configcls = CubicWebServerConfig

        From Windmill configuration:

        .. attribute:: browser

            identification string (firefox|ie|safari|chrome) (firefox by default)

        .. attribute :: edit_test

            load and edit test for debugging (False by default)

        .. attribute:: test_dir (optional)

            testing file path or directory (windmill directory under your unit case

            file by default)

        Examples:

            browser = 'firefox'

            test_dir = osp.join(__file__, 'windmill')

            edit_test = False

        If you prefer, you can put here the use cases recorded by windmill GUI

        (services transformer) instead of the windmill sub-directory

        You can change `test_dir` as following:

            test_dir = __file__

        Instead of toggle `edit_test` value, try `python <test script> -f`
