Signature de la méthode isolation

def isolation(self, input: Union[str, bytes, IO, NoneType] = None, env: Optional[Mapping[str, Optional[str]]] = None, color: bool = False) -> Iterator[Tuple[_io.BytesIO, Optional[_io.BytesIO]]] 

Description

isolation.__doc__

A context manager that sets up the isolation for invoking of a
        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
            Added the ``color`` parameter.
