    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.
    :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

        command line tool.  This sets up stdin with the given input data
        and `os.environ` with the overrides from the given dictionary.
        This also rebinds some internals in Click to be mocked (like the
        prompt functionality).

        This is automatically done in the :meth:`invoke` method.

        :param input: the input stream to put into sys.stdin.
        :param env: the environment overrides as dictionary.
        :param color: whether the output should contain color codes. The
                      application can still override this explicitly.

        .. versionchanged:: 8.0
            ``stderr`` is opened with ``errors="backslashreplace"``
            instead of the default ``"strict"``.

        .. versionchanged:: 4.0

        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.

        :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
                     :func:`shlex.split`.
        :param input: the input data for `sys.stdin`.
        :param env: the environment overrides.
        :param catch_exceptions: Whether to catch any other exceptions than
                                 ``SystemExit``.
        :param extra: the keyword arguments to pass to :meth:`main`.
        :param color: whether the output should contain color codes. The
                      application can still override this explicitly.

        .. versionchanged:: 8.0
            The result object has the ``return_value`` attribute with
            the value returned from the invoked command.

        .. versionchanged:: 4.0
            Added the ``color`` parameter.

        .. versionchanged:: 3.0
            Added the ``catch_exceptions`` parameter.

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