RS( s� The CLI runner provides functionality to invoke a Click command line
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

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

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.
.. versionadded:: 3.0
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
: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.
