Std.Test.fails

fn

This is a callable function.

What it does

A check that holds exactly when the one it is given does not.

For a failure that is known and expected — a bug being tracked, a limit

being documented. It reports when the inner check starts holding, which is

what turns a known failure into something that tells you when it is fixed

rather than something that stays red until someone looks.
