NAME

Test - Rakudo Testing Library

SYNOPSIS

  use Test;

DESCRIPTION

FUNCTIONS

  throws_like($code, Mu $expected_type, *%matchers)

If $code is Callable, calls it, otherwise EVALs it, and expects it thrown an exception.

If an exception is thrown, it is compared to $expected_type.

Then for each key in %matchers, a method of that name is called on the resulting exception, and its return value smart-matched against the value.

Each step is counted as a separate test; if one of the first two fails, the rest of the tests are skipped.

From @usev6

Fixed with commit rakudo/rakudo@3c00699

I don't think this warrants a test (at least not in roast). Therefore I'm closing this ticket as 'resolved' now. Please reopen or add a test to Rakudo's t/02-rakudo if you disagree.

@usev6 - Status changed from 'new' to 'resolved'
