8.
If you have any questions
around the modules, you
can ask me after this talk.

9.
Do you like testing?

10.
Do you like TDD?

11.
Then…

12.
History of Perl testing
libraries…!

13.
Test::More, Test::Class

14.
Test::More
use Test::More tests => 1;
ok(“dan” eq “kogai”);

15.
Test::Class

16.
Architecture
Test::Builder
Test::More Test::Class
Test::Excepti
ons
etc…

17.
Test::Builder
• Counts number of tests
• Counts number of Failures
• Counts number of Succeeded.

18.
TAP!

19.
Test Anything
Protocol

20.
Latest enhancements
• subtest
• done_testing

21.
subtest 'feature2', sub {
ok 1, 'it works';
ok 0, 'it looks great';
};
done_testing;

22.
TAP with prove

23.
prove eats TAP

24.
Test::Builder is
evolving…

25.
Test::Builder2
• It may started at 2011.
• With dreams…

26.
TB2
• Custom output
• Full rewrite
• OO-ish APIs

27.
But…

28.
We need workaround
for now…!

29.
Test::Pretty 爆誕

30.
Pretty output without
code modifications!

31.
めっちゃ見やすい!!

32.
How it works?

33.
Monkey patching…

34.
But it works. Maybe.

35.
It’s not a big problem.
Because this is a
workaround for now.

36.
Test::Ika

37.
RSpec like testing
framework for Perl5

38.
Ika?

39.
Ika =

40.
Please check it, if you
love RSpec.

41.
Test::More の停滞
Development has stagnated

42.
Test::Builder2
• It may started at 2011.
• With dreams…
• It was gone. ← NEW!

43.
Test::More x.xx was
released.

44.
Then…

45.
I can’t wait evolution.

46.
Test::Kantan 爆誕

47.
Yet another testing
framework

48.
Test::Kantan is not
based on Test::Builder

49.
What’s new?

50.
subtests with hooks

51.
before_each
after_each

52.
IIRC
jasmine inspired
interfaces.

53.
BDD Style

54.
Given-When-Then

55.
Plain old Test::More
style

56.
Assertions

57.
ok { $foo->bar() eq ‘baz’ };

58.
Power Assert
hooks B optree.

59.
ok { x(x($foo)->bar())
eq ‘baz’ };

60.
expect($x)->to_be_true;

61.
Shows testing details
if it’s failed.

62.
All or nothing.
pass or die;

63.
Conclusion

64.
Conclusion
• Test::SharedFork
• Test::TCP
• Test::Pretty
• Test::Ika
• Test::Kantan ← NEW!

65.
Enjoy testing!

66.
Thanks
