NAME

6       Test2::Compare::Custom - Custom field check for comparisons.
7

DESCRIPTION

9       Sometimes you want to do something complicated or unusual when
10       validating a field nested inside a deep data structure. You could pull
11       it out of the structure and test it separately, or you can use this to
12       embed the check. This provides a way for you to write custom checks for
13       fields in deep comparisons.

SYNOPSIS

16           my $cus = Test2::Compare::Custom->new(
17               name => 'IsRef',
18               operator => 'ref(...)',
19               code => sub {
20                   my %args = @_;
21                   return $args{got} ? 1 : 0;
22               },
23           );
24
25           # Pass
26           is(
27               { a => 1, ref => {},   b => 2 },
28               { a => 1, ref => $cus, b => 2 },
29               "This will pass"
30           );
31
32           # Fail
33           is(
34               {a => 1, ref => 'notref', b => 2},
35               {a => 1, ref => $cus,     b => 2},
36               "This will fail"
37           );
38

ARGUMENTS

40       Your custom sub will be passed 4 arguments in a hash:
41
42           code => sub {
43               my %args = @_;
44               # provides got, exists, operator, name
45               return ref($args{got}) ? 1 : 0;
46           },
47
48       $_ is also localized to "got" to make it easier for those who need to
49       use regexes.
50
51       got
52       $_  The value to be checked.
53
54       exists
55           This will be a boolean. This will be true if "got" exists at all.
56           If "exists" is false then it means "got" is not simply undef, but
57           doesn't exist at all (think checking the value of a hash key that
58           does not exist).
59
60       operator
61           The operator specified at construction.
62
63       name
64           The name provided at construction.
65

METHODS

67       $code = $cus->code
68           Returns the coderef provided at construction.
69
70       $name = $cus->name
71           Returns the name provided at construction.
72
73       $op = $cus->operator
74           Returns the operator provided at construction.
75
76       $bool = $cus->verify(got => $got, exists => $bool)
