Feature or enhancement

Proposal:

After implementing HACL* HMAC in #99108, I've observed that I didn't test all code paths and that some tests I assumed were a bit incorrect (some redundancy was done). This is an issue to track all improvements done to HMAC tests (I'm planning to target an almost 100% coverage), but I'll close it when nothing needs to be done "for now".

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
