    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
                       independently

        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

        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.

        changes the current working directory to it. This isolates tests
        that affect the contents of the CWD to prevent them from
        interfering with each other.

            when exiting.
