[Fiona] this looks more like a test code bug rather than an indication that the device doesn't support modinv. SO should still return -1.
Also - while you're updating, can you please fix the typo in the trace - ASYNC should be ASYMM

[Ayuj]  Each test execute if device supports that algorithm else it is skipped. Thus, here it checks if modinv is not supported in capability then skip the test, which looks okay to me.

So, why do you say it is a bug?

Probably message is not proper should have been "Device doesn't support MODINV"

Will update typo.

[Fiona] please update the trace to match the return, e.g. something like "modulus length %len not supported by this device"
[Ayuj] Sure.

[Fiona] same as above, i.e. code bug. And typo in trace.

[Fiona] same as above. Fix trace.
