We're using Test::Warnings in other tests. Might as well use it here too. That means you need to make it optional with Test::Requires but all the optional tests get run by travis so that's ok.

I'm not entirely clear on how to write this test using Test::Warnings - some of this might be lack of familiarity on my end about when exactly Perl decides to display the warnings: when I replace use, with require, I don't see the DEMOLISH warning. And I don't see how to wrap warnings {} around a use statement - any suggestions?

There are a few ways, but the easiest is probably just to load Test::Warnings, load the module in question, and then use had_no_warnings() to do the actual test.

A comment explaining why this is necessary would be good.
Per pull request moose#167, add comments better explaining why these changes are necessary, and use Test::Warnings

Alright, made those tweaks. Sorry for the delay - as noted in our other thread I was spending some time away from computers in California and Yosemite :) |

There's no need to put in a test count.

I think if you add Test::Warnings->import(':no_end_test') here then it will only run one test.

Could we move this into a block in the .t file? I think that'd make it a bit clearer.

FYI I accidentally rewrote the commit history (I amended the first post-review commit), but realized that was silly and did some git surgery to put it back. The results should be what we want now. |

Fix for https://rt.cpan.org/Public/Bug/Display.html?id=124194
Single calls to demolish had the potential to emit warnings. This silences 'em.
