Have you seen Cucumber? https://cucumber.io/docs It's a system that attempts to enable specifications for a software product to be written in a way that can be parsed by an automated testing framework.

In theory, you carefully say what you want the software to do in given scenarios, human developers understand the spec as-is, and automated tests can read and execute the spec as-is as a test.

I have no professional experience with it because all the docs make it look like something I would run from: lots of in-code scaffolding and talking like a computer just to get the same job done. But maybe you'll like it.
