> There is a long-lived and incredible community of classic gaming emulation work online for it to reference. And that community has created…conformance tests! Opus found them and built against one, that has >3k golden instructions

I'm doing something similar but not for an emulator, using tests other projects in a similar space use to validate things.

I also know a friend that feeds Claude Gherkin formatted test criteria, and apparently that yields insanely good Claude output.

I said last year to people that I swear BDD is going to make a comeback. Hasn’t yet, but I still reckon it might!

Any good recommended reading?

They are talking about Cucumber, a behavior driven development platform. Gherkin is a syntax for writing test cases:

Very neat, seems quite appropriate for the way people currently work with LLMs.

I'd just ask Claude about writing test specs in Gherkin. I'm going to try this Monday.
