What is the problem this feature would solve?

I'm writing @lishaduck/effect-platform-deno and am currently in the process of porting over @effect/platform-node-shared's tests. I've swapped them over to it.effect to make failures easier to read, but there's not a .fail function for when I know tests don't pass yet.

What is the feature you are proposing to solve the problem?

Add in the .fail function from vitest core.

What alternatives have you considered?

Skipping them.
