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

21. Latest enhancements
• subtest
• done_testing

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

24. TAP with prove

25. prove eats TAP

27. Test::Builder is
evolving…

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

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

30. But…

31. We need workaround
for now…!

32. Test::Pretty 爆誕

33. Pretty output without
code modifications!

38. めっちゃ見やすい!!

39. How it works?

40. Monkey patching…

41. But it works. Maybe.

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

43. Test::Ika

44. RSpec like testing
framework for Perl5

45. Ika?

46. Ika =

47. Please check it, if you
love RSpec.

48. Test::More の停滞
Development has stagnated

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

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

51. Then…

52. I can’t wait evolution.

53. Test::Kantan 爆誕

54. Yet another testing
framework

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

56. What’s new?

57. subtests with hooks

58. before_each
after_each

59. IIRC
jasmine inspired
interfaces.

60. BDD Style

62. Given-When-Then

64. Plain old Test::More
style

66. Assertions

67. ok { $foo->bar() eq ‘baz’ };

68. Power Assert
hooks B optree.

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

70. expect($x)->to_be_true;

71. Shows testing details
if it’s failed.

75. All or nothing.
pass or die;

76. Conclusion

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

78. Enjoy testing!

79. Thanks
