Unreliable test timings! On an initial run, this test took 632.78ms, which exceeded the deadline of 200.00ms, but on a subsequent run it took 0.34 ms, which did not. If you expect this sort of variability in your test timings, consider turning deadlines off for this test by setting deadline=None.
=============================== warnings summary ===============================

likely not critical, still the different in run time is surprising.

Thanks! Yes, we noticed that before but it slipped due to other priorities, good it's now here so we don't forget!
