                    used (envisaged for testing purposes only)

                extra_env (dict): Extra items to add to the environment
                    (neither requires nor precludes env)
                fail_on_error (bool): Raise an exception if the subprocess returns
                    an error. Default is True. The return code is available as
                    ``exe.returncode``
                ignore_errors (int or list): A list of error codes to ignore.
                    If these codes are returned, this process will not raise
                    an exception even if ``fail_on_error`` is set to ``True``

                error: Where to send stderr
    
            Accepted values for input, output, and error:
    
            * python streams, e.g. open Python file objects, or ``os.devnull``
            * filenames, which will be automatically opened for writing
            * ``str``, as in the Python string type. If you set these to ``str``,
              output and error will be written to pipes and returned as a string.
              If both ``output`` and ``error`` are set to ``str``, then one string
              is returned containing output concatenated with error. Not valid
              for ``input``
    
            By default, the subprocess inherits the parent's file descriptors.
