NAME ^

Benchmark::Confirm - take a Benchmark and confirm returned values

SYNOPSIS ^

for example, it is ordinary to execute benchmark script...

    perl some_benchmark.pl

and use Benchmark::Confirm

    perl -MBenchmark::Confirm some_benchmark.pl

then you get the result of benchmark and the confirmination.

    Benchmark: timing 1 iterations of Name1, Name2, Name3...
         Name1:  0 wallclock secs ( 0.00 usr +  0.00 sys =  0.00 CPU)
                (warning: too few iterations for a reliable count)
         Name2:  0 wallclock secs ( 0.00 usr +  0.00 sys =  0.00 CPU)
                (warning: too few iterations for a reliable count)
         Name3:  0 wallclock secs ( 0.00 usr +  0.00 sys =  0.00 CPU)
                (warning: too few iterations for a reliable count)
                        Rate Name3 Name1 Name2
    Name3 10000/s    --    0%    0%
    Name1 10000/s    0%    --    0%
    Name2 10000/s    0%    0%    --
    ok 1
    ok 2
    ok 3
    1..3

See the last 4 lines, these are the result of confirmation.

DESCRIPTION ^

Benchmark::Confirm displays a confirmation after benchmarks that the each values from benchmark codes are equivalent or not.

All you have to do is to use Benchmark::Confirm instead of Benchmark.

However, if you write some benchmarks in the one script, you should call some methods from Benchmark::Confirm. for more details see below METHODS section.

METHODS ^

See Benchmark#Standard_Exports and Benchmark#Optional_Exports sections.

Moreover, atonce and reset_confirm these functions are only for Benchmark::Confirm.

atonce

atonce function confirms values manually.

You can use this function when you write some benchmarks in one script. Or you shuld use reset function instead on between some benchmarks.

    use strict;
    use warnings;

    use Benchmark::Confirm qw/timethese/;

    {
        my $result = timethese( 1 => +{
            Name1 => sub { "something" },
            Name2 => sub { "something" },
            Name3 => sub { "something" },
        });
    }

    Benchmark::Confirm->atonce;

    {
        my $result = timethese( 1 => +{
            Name1 => sub { 1 },
            Name2 => sub { 1 },
            Name3 => sub { 1 },
        });
    }

reset_confirm

This function resets stacks of returned value.

CAVEATS ^

If benchmark code returns CODE reference, then Benchmark::Confirm treats it as string value: 'CODE'. This may change in future releases.
