we might need to make this a function. Something like

def requires_numpy_2(reason=None):
    if reason is None:
        reason = "requires numpy >= 2"
    return pytest.mark.skipif(np.lib.NumpyVersion(np.__version__) < "2.0.0b1", reason=reason)

...

@requires_numpy_2(reason="trapezoid added in numpy2")
def test_trapezoid(self):
    ...

could work. Otherwise it is possible to skip the entire test module if numpy is not available:

pytest.importorskip("numpy")

of course there was a helper for it all along...
