Embrace Your Inner Grumpy Metatesting in 2016 Chris Hartjes GPUG
- January 27, 2016
A little something about me • PHP user since 1998
• testing advocate since 2004 • writer of PHP books at http://grumpy-learning.com • working at Mozilla as QA engineer in Cloud Services • organize TrueNorthPHP • /dev/hell podcast • OpenCFP head honcho
What is Metatesting?
It starts with… Magic: The Gathering?
Mature Testing Tools Are Available
Mature Testing Tools • PHPUnit — http://phpunit.de • Behat —
http://behat.org • PHPSpec — http://www.phpspec • Codeception — http://codeception.com
Mature Testing Tools • Don’t reinvent mature tools • Extend
them for your own needs
Open Source Drives Acceptance
Open Source • Every popular framework has extensive test suites
• Lack of tests speaks volumes about intent • Great entry point into contributing
Proof Exists To Back The Promises
Proof Exists • Study commissioned by IBM and Microsoft •
White paper -> http://research.microsoft.com/en- us/groups/ese/nagappan_tdd.pdf
Proof Exists • TDD clearly takes more time… • …but
results in fewer bugs in production
“Hey boss, for just one extra day per week on
this project we can get up to 90% fewer bugs making it into production”
Testing Moves Bugs To A Cheaper Phase
Cheaper Fixes • cheapest time to fix bugs is when
the developer finds them during their work • cost of bugs needs to be evaluated as multiples of developer costs
Cheaper Fixes • cultural costs • opportunity costs
Build Systems Are Finally Easy To Use
Build Systems • Jenkins — https://jenkins-ci.org • Travis-CI — https://travis-ci.org
Build Systems • Great side effects • Highlights pain points
Awesome Complementary Tools
Complementary Tools • code coverage • static analysis
Complementary Tools • Code Climate — https://codeclimate.com • Scrutinizer —
https://scrutinizer-ci.com
“Tracking improvements via tests lets you know the team is
on track and doing good work.”
It will never be more difficult to test PHP code
The time investment in tests produces tangible results
I still suck at Magic but are good at Metatesting
