If you're going Deno, I suggest trying the integrated test runner, it's quite good and the experience OOB is nice.

What I like about the Cucumber setup is the definition of Feature files in Gherkin that define your test scenarios and having the actual step implementations decoupled of that. This allows for very easy reusability of all my steps across multiple scenarios.

As far as I can see, this is not the way to go with the integrated test tooling (or not even possible).
