in reply to Assigning to a ArrayRef accessor type

Hello tomred, and congratulations on your first post!

MockObj::files is not an array, it’s an array reference. So instead of assigning to an array variable:

my @strings = $mock->files;
[download]

you should assign to a scalar:

my $strings = $mock->files;
note explain $strings;

cmp_deeply($strings, bag(@list));
[download]

which gives the desired test result:

 1:14 >perl 2056_SoPW.pl
# [
#   'string one',
#   'Different string',
#   'With feeling'
# ]
# [
#   'string one',
#   'Different string',
#   'With feeling'
# ]
ok 1
1..1

Hope that helps,

An alternative to this: `my $strings = $mock->files;` [download] Would be this: `my @strings = @{ $mock->files };` [download] Or if you've got a very recent version of Perl: `my @strings = $mock->files->@*;` [download] Moose also has an optional feature where it can detect if an accessor is called in a list context and return a list instead of a reference, but Moo didn't implement that because it can get confusing to work with. toby döt ink	[reply] [d/l] [select]
