Simple unit test

HoloViews

Hi,

Hope you are all safe and well.

Do you know what I am doing wrong here? I am trying to do a simple unit test but can’t get started.

My assumption is that these are the same and should pass (or almost equal if I was using floats).

Best,
Douglas

import holoviews as hv

hv.__version__ # '1.14.5'

a = [1, 2]
c1 = hv.Curve(a)
c2 = hv.Curve(a)
hv.element.comparison.Comparison.assertEqual(c1, c2)

      4 c1 = hv.Curve(a)
      5 c2 = hv.Curve(a)

I think Assert Equal is a simple test and for a curve I need

hv.element.comparison.Comparison.compare_curve(hv.Curve([1,2]), hv.Curve([1,2]))

Nope, still struggling. Any thoughts on this?

hv.element.comparison.Comparison.compare_overlays(hv.Curve([1,2]) * hv.Curve([1,2]), hv.Curve([1,2]) * hv.Curve([1,2]))

Looking at the code, it seems to again do simple comparisons of the contained objects rather than curve v curve comparison etc…
