Re^2: Error: Can't locate Test/Exception.pm in @INC (you may need to install the Test::Exception module) on CPANPLUS

Hello haukex,

Thanks for the complete analysis and solution to my problem.

I kept looking online and I found also that most people also propose to use Test::Fatal I will give it a try. Thanks again on showing me how to include it on my Makefile.PL I completely forgot about that, since the last module that I wrote was almost 4 years ago.

On the mean time, I was experimenting and I also found a successful way of testing croak without the use of any secondary test module but with the use of Test::More/like (fellow monk toolic proposed this on Testing error handling that calls "die"), sample below:

$@ = '';
eval { hexDumperOutput('Test', '這是一個測試') };
like( $@, qr/Unknown encoding format 'Test'/,
      'Check encoding formats hexDumperOutput' );

Again thanks a lot for your time and effort, it helped me a lot.

like( $@, qr/Unknown encoding format 'Test'/,

Yes, despite some long-standing issues with $@, since this code is explicitly checking for a specific value, that should work ok too, without any extra modules. Test::Fatal uses Try::Tiny internally, which works around some of the issues with $@. Three of my four CPAN modules use Test::Fatal extensively for testing with no problems across all of CPAN Testers.

testing croak without the use of any secondary test module

I realized the other day that since all I was using from Test::Fatal was its exception function, I could successfully replace it with the following, with no changes to my tests necessary. However, this still theoretically suffers from the same problems I linked to earlier.

sub exception (&) {
    return eval { shift->(); 1 } ? undef
        : ($@ || confess "\$@ was false");
}
