Thanks @jacobbohlin! I left a few comments, let me know what you think

[lhutton1]

I think we could just remove this section completely?

[jacobbohlin]

Agreed, that's probably better.

[lhutton1]

It would be interesting to see if the output tolerance could be lowered now that we support more operators

[jacobbohlin]

I can give that a try.

[lhutton1]

Is it worth parameterising this network like the above?

[jacobbohlin]

I cannot say I have a definitive answer for this. Probably not the most efficient way to improve test coverage relative to test time.

Thanks @jacobbohlin

I think we could refactor the tests here to be a single one with stimulus being the model url and accelerator variant.
Moreover, lets write out a tuples of model url and accelerator variants for each tests -- therefore we have more control/visibility of what is being tested as opposed default parametric explosion of the test space.

Some references that we have done this at other places, also feel free to migrate any utility that you feel we can re-use to aot_test_utils

Thanks @manupa-arm. That is a much better approach, I will update according to your suggestions.

[lhutton1]

Thanks @jacobbohlin LGTM!
