(Test) sub fails-like

Defined as:

sub fails-like ( \test where Callable:D|Str:D$ex-type$reason?*%matcher)

Same interface as throws-like, except checks that the code returns a Failure instead of throwing. If the code does throw or if the returned Failure has already been handled, that will be considered as a failed test.
