Test2::Tools::PDL - Test2 tools for verifying Perl Data Language piddles
version 0.001
use Test2::Tools::PDL; # Functions are exported by default. # Ensure something is a piddle. pdl_ok($x); # Compare two piddles. pdl_is($got, $expected, 'Same piddle.');
Checks that the given $thing is a PDL object.
$thing
Checks that piddle $got is same as $exp.
$got
$exp
Now this method is internally similar as is($got->unpdl, $exp->unpdl). It's possible to work with both numeric PDLs as well as non-numeric PDLs (like PDL::Char, PDL::SV).
is($got->unpdl, $exp->unpdl)
This module contains tools for verifying PDL piddles.
This module can be configured by some module variables.
These two variables are used when comparing float piddles. For pdl_is($got, $exp, ...), the effective tolerance is $TOLERANCE + abs($TOLERANCE_REL * $exp).
pdl_is($got, $exp, ...)
$TOLERANCE + abs($TOLERANCE_REL * $exp)
Default value of $TOLERANCE is same as $Test2::Compare::Float::DEFAULT_TOLERANCE, which is 1e-8. Default value of $TOLERANCE_REL is 0.
$TOLERANCE
$Test2::Compare::Float::DEFAULT_TOLERANCE
1e-8
$TOLERANCE_REL
For example, to use only relative tolerance,
{ local $Test2::Tools::PDL::TOLERANCE = 0; local $Test2::Tools::PDL::TOLERANCE_REL = 1e-6; ... }
