Note: #320 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

    This is the lowest-level retry helper. Generally, you'll use the
    higher-level retry helper :class:`Retry`.

    Args:
        target(Callable): The function to call and retry. This must be a
            nullary function - apply arguments with `functools.partial`.
        predicate (Callable[Exception]): A callable used to determine if an
            exception raised by the target should be considered retryable.
            It should return True to retry or False otherwise.
        sleep_generator (Iterable[float]): An infinite iterator that determines
            how long to sleep between retries.
        deadline (float): How long to keep retrying the target. The last sleep
            period is shortened as necessary, so that the last retry runs at
            ``deadline`` (and not considerably beyond it).
        on_error (Callable[Exception]): A function to call while processing a
            retryable exception.  Any error raised by this function will *not*
            be caught.

    Returns:
        Any: the return value of the target function.

    Raises:
        google.api_core.RetryError: If the deadline is exceeded while retrying.
