def setastest(tf=True):
    """
    Signals to nose that this function is or is not a test.

    Parameters
    ----------
    tf : bool
        If True, specifies that the decorated callable is a test.
        If False, specifies that the decorated callable is not a test.
        Default is True.

    Notes
    -----
    This decorator can't use the nose namespace, because it can be
    called from a non-test module. See also ``istest`` and ``nottest`` in
    ``nose.tools``.

    Examples
    --------
    `setastest` can be used in the following way::

      from numpy.testing.decorators import setastest

      @setastest(False)
      def func_with_test_in_name(arg1, arg2):
          pass

    """
    def set_test(t):
        t.__test__ = tf
        return t
    return set_test
