NAME
Test2::Tools::ClassicCompare - Classic (Test::More style) comparison tools.
DESCRIPTION
This provides comparison functions that behave like they did in Test::More, unlike the Test2::Tools::Compare plugin which has modified them.
SYNOPSIS
use Test2::Tools::ClassicCompare qw/is is_deeply isnt like unlike cmp_ok/;
is($got, $expect, "These are the same when stringified");
isnt($got, $unexpected, "These are not the same when stringified");
like($got, qr/.../, "'got' matches the pattern");
unlike($got, qr/.../, "'got' does not match the pattern");
is_deeply($got, $expect, "These structures are same when checked deeply");
cmp_ok($GOT, $OP, $WANT, 'Compare these items using the specified operatr');EXPORTS
- $bool = is($got, $expect)
- $bool = is($got, $expect, $name)
- $bool = is($got, $expect, $name, @diag)
-
This does a string comparison of the two arguments. If the two arguments are the same after stringification the test passes. The test will also pass if both arguments are undef.
The test
$nameis optional.The test
@diagis optional, it is extra diagnostics messages that will be displayed if the test fails. The diagnostics are ignored if the test passes.It is important to note that this tool considers
"1"and"1.0"to not be equal as it uses a string comparison.See Test2::Tools::Compare if you want an
is()function that tries to be smarter for you. - $bool = isnt($got, $dont_expect)
- $bool = isnt($got, $dont_expect, $name)
- $bool = isnt($got, $dont_expect, $name, @diag)
-
This is the inverse of
is(), it passes when the strings are not the same. - $bool = like($got, $pattern)
- $bool = like($got, $pattern, $name)
- $bool = like($got, $pattern, $name, @diag)
-
Check if
$gotmatches the specified pattern. Will fail if it does not match.The test
$nameis optional.The test
@diagis optional. It contains extra diagnostics messages that will be displayed if the test fails. The diagnostics are ignored if the test passes. - $bool = unlike($got, $pattern)
- $bool = unlike($got, $pattern, $name)
- $bool = unlike($got, $pattern, $name, @diag)
-
This is the inverse of
like(). This will fail if$gotmatches$pattern. - $bool = is_deeply($got, $expect)
- $bool = is_deeply($got, $expect, $name)
- $bool = is_deeply($got, $expect, $name, @diag)
-
This does a deep check, comparing the structures in
$gotwith those in$expect. It will recurse into hashrefs, arrayrefs, and scalar refs. All other values will be stringified and compared as strings. It is important to note that this tool considers"1"and"1.0"to not be equal as it uses a string comparison.This is the same as
Test2::Tools::Compare::is(). - cmp_ok($got, $op, $expect)
- cmp_ok($got, $op, $expect, $name)
- cmp_ok($got, $op, $expect, $name, @diag)
-
Compare
$gotto$expectusing the operator specified in$op. This is effectively aneval "\$got $op \$expect"with some other stuff to make it more sane. This is useful for comparing numbers, overloaded objects, etc.Overloading Note: Your input is passed as-is to the comparison. If the comparison fails between two overloaded objects, the diagnostics will try to show you the overload form that was used in comparisons. It is possible that the diagnostics will be wrong, though attempts have been made to improve them since Test::More.
Exceptions: If the comparison results in an exception then the test will fail and the exception will be shown.
cmp_ok()has an internal list of operators it supports. If you provide an unsupported operator it will issue a warning. You can add operators to the%Test2::Tools::ClassicCompare::OPShash, the key should be the operator, and the value should either be 'str' for string comparison operators, 'num' for numeric operators, or any other true value for other operators.Supported operators:
