NAME
Test::Deep::NumberTolerant - A Test::Deep plugin for testing numbers within a tolerance range
VERSION
version 0.001
SYNOPSIS
use Test::More;
use Test::Deep;
use Test::Deep::NumberTolerant;
cmp_deeply(
{
counter => 123,
},
{
counter => within_tolerance(100, plus_or_minus => 50),
},
'counter field is 100 plus or minus 50',
);
DESCRIPTION
Test::Deep::NumberTolerant
provides the sub within_tolerance
to indicate that the data being tested matches the equivalent tolerance(...)
value.
I wrote this because I found myself doing this a lot:
cmp_deeply(
$thing,
methods(
delete_time => methods(epoch => code( sub { $_[0] == tolerance(time(), plus_or_minus => 2) || (0, "got $_[0], expected ", time()) } )),
),
'object has been deleted',
);
With this module, this can be simplified to the much more readable:
cmp_deeply(
$thing,
methods(
delete_time => methods(epoch => within_tolerance(time(), plus_or_minus => 2)),
),
'object has been deleted',
);
FUNCTIONS
within_tolerance
Exported by default; to be used within a Test::Deep comparison function such as cmp_deeply. Accepted arguments are the same as for "tolerance" in Number::Tolerant
.
