It’s an interesting API design. Clearly borrows from existing test frameworks, but with some unusual idiosyncrasies (options arg) which feel somewhat awkward. That said, I’ve been working on a test framework in my spare time… for reasons, mostly performance and DX. I’ll get more detailed as it gets closer to ready for early users. But this looks like it at least has potential to be a good low level foundation to build other features on. Worth a spike to see if it’s a good fit, now I know what to do with my Sunday!
