# 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](http://search.cpan.org/perldoc?Benchmark\#Standard\_Exports) and [Benchmark\#Optional\_Exports](http://search.cpan.org/perldoc?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. # REPOSITORY Benchmark::Confirm is hosted on github # AUTHOR Dai Okabayashi # SEE ALSO [Benchmark](http://search.cpan.org/perldoc?Benchmark) # LICENSE This module is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
