class OutputCapture(object):
    """
    A context manager for capturing output to the
    :any:`sys.stdout` and :any:`sys.stderr` streams.

:param separate: If ``True``, ``stdout`` and ``stderr`` will be captured
                     separately and their expected values must be passed to
                     :meth:`~OutputCapture.compare`.

:param fd: If ``True``, the underlying file descriptors will be captured,
               rather than just the attributes on :mod:`sys`. This allows
               you to capture things like subprocesses that write directly
               to the file descriptors, but is more invasive, so only use it
               when you need it.

:param strip_whitespace:
        When ``True``, which is the default, leading and training whitespace
        is trimmed from both the expected and actual values when comparing.

.. note:: If ``separate`` is passed as ``True``,
              :attr:`OutputCapture.captured` will be an empty string.
