--------------------------------------------- /Users/gugod/dev/Acme-Greeting/t/01.english.t (Wstat: 65280 Tests: 5 Failed: 1) Failed test: 5 Non-zero exit status: 255 Parse errors: Bad plan. You planned 4 tests but ran 5. Files=1, Tests=5, 0 wallclock secs ( 0.00 usr 0.01 sys + 0.05 cusr 0.01 csys = 0.07 CPU) Result: FAIL [MSG]: /Users/gugod/Acme-Greeting/t/01.english.t was changed. /Users/gugod/dev/Acme-Greeting/t/01.english......ok --------------------------------------------- Result: PASS [MSG]: /Users/gugod/dev/Acme-Greeting/t/01.english.t was changed. /Users/gugod/dev/Acme-Greeting/t/01.english......ok ---------------------------------------------

What It Does... 1. Scan modiﬁed ﬁles 2. Find all tests requiring a re-run. 3. Run those tests 4. Report PASS / FAIL 5. GOTO 1

How it’s done 1. Scan modified files. File::Modified 2. Find all tests requiring a re-run. Module::ExtractUse 3. Run those tests. App::Prove 4. Report PASS / FAIL. Log::Dispatch 5. GOTO 1. while(1)

CPANFTW CPAN For The Win

Good For...

Test Driven Development

Test Driven Refactoring

<CODE>

What It Does (1st day) 1. Wait until any ﬁle is modiﬁed 2. Run all tests 3. Report PASS / FAIL 4. GOTO 1

Run ALL tests

Wasting Time

Write less test

bad software

hate software

Run as few tests as possible Module::ExtractUse

Only run .t if that’s modiﬁed

dependency of .t

Moose.pm moose.t Cow.pm cow.t OX.pm ﬁght.t

Log::Dispatch based notiﬁcation Should be easy extend

Log::Dispatch::Screen

/me Mac

Good developing platform and macbook air is so shiny

Growl Universal Reminder http://growl.info

Log::Disptach::MacGrowl auto-used if installed

Not good enough...

Only check .pm dependency .pm → .t .c → .t .conf → .t .yaml → .t

Shallow Dependency

Animal.pm Moose.pm Cow.pm cow.t moose.t

isa Animal.pm Moose.pm Cow.pm cow.t moose.t

isa Animal.pm Moose.pm isa Cow.pm cow.t moose.t

isa Animal.pm Moose.pm isa tested by Cow.pm cow.t moose.t

isa Animal.pm Moose.pm isa tested by tested by Cow.pm cow.t moose.t

isa Animal.pm Moose.pm tested by isa tested by animal.t tested by Cow.pm cow.t moose.t

Should clearly notiﬁed what’s failed

No High-Def cute looking icon ICON DESIGNER WANTED

Future • Better Dependency Detection • Convention based (For Catalyst / Jifty / Others) • Conﬁguration based • Support other Universal Reminder on other platform. (Twitter!)

Happy Testing
