If you have any questions around the modules, you can ask me after this talk.

Do you like testing?

Do you like TDD?

Then…

History of Perl testing libraries…!

Test::More, Test::Class

Test::More

use Test::More tests => 1;

ok(“dan” eq “kogai”);

Test::Class

ArchitectureTest::Builder

Test::More Test::Class Test::Exceptions

etc…

Test::Builder

• Counts number of tests

• Counts number of Failures

• Counts number of Succeeded.

TAP!

Test Anything Protocol

Latest enhancements

• subtest • done_testing

subtest 'feature2', sub { ok 1, 'it works'; ok 0, 'it looks great'; }; done_testing;

TAP with prove

prove eats TAP

Test::Builder is evolving…

Test::Builder2

• It may started at 2011. • With dreams…

TB2

• Custom output • Full rewrite • OO-ish APIs

But…

We need workaround for now…!

Test::Pretty 爆誕

Pretty output without code modifications!

めっちゃ見やすい!!

How it works?

Monkey patching…

But it works. Maybe.

It’s not a big problem. Because this is a

workaround for now.

Test::Ika

RSpec like testing framework for Perl5

Ika?

Ika =

Please check it, if you love RSpec.

Test::More の停滞 Development has stagnated

Test::Builder2

• It may started at 2011. • With dreams… • It was gone. ← NEW!

Test::More x.xx was released.

Then…

I can’t wait evolution.

Test::Kantan 爆誕

Yet another testing framework

Test::Kantan is not based on Test::Builder

What’s new?

subtests with hooks

before_each after_each

jasmine inspired interfaces.

IIRC

BDD Style

Given-When-Then

Plain old Test::More style

Assertions

ok { $foo->bar() eq ‘baz’ };

Power Assert hooks B optree.

ok { x(x($foo)->bar()) eq ‘baz’ };

expect($x)->to_be_true;

Shows testing details if it’s failed.

All or nothing. pass or die;

Conclusion

Conclusion

• Test::SharedFork

• Test::TCP

• Test::Pretty

• Test::Ika

• Test::Kantan ← NEW!

Enjoy testing!

Thanks
