    script for unittesting purposes in a isolated environment.  This only
    works in single-threaded systems without any concurrency as it changes the
    global interpreter state.

    :param charset: the character set for the input and output data.  This is
                    UTF-8 by default and should not be changed currently as
                    the reporting to Click only works in Python 2 properly.
    :param env: a dictionary with environment variables for overriding.
    :param echo_stdin: if this is set to `True`, then reading from stdin writes
                       to stdout.  This is useful for showing examples in
                       some circumstances.  Note that regular prompts
                       will automatically echo the input.
    :param mix_stderr: if this is set to `False`, then stdout and stderr are
                       preserved as independent streams.  This is useful for
                       Unix-philosophy apps that have predictable stdout and
                       noisy stderr, such that each may be measured
                       independently

        forwarded directly to the command line script, the `extra` keyword
        arguments are passed to the :meth:`~clickpkg.Command.main` function of
        the command.

        This returns a :class:`Result` object.

           The ``catch_exceptions`` parameter was added.

        .. versionchanged:: 3.0
           The result object now has an `exc_info` attribute with the
           traceback if available.

        .. versionadded:: 4.0
           The ``color`` parameter was added.

        :param cli: the command to invoke
        :param args: the arguments to invoke. It may be given as an iterable
                     or a string. When given as string it will be interpreted
                     as a Unix shell command. More details at
