About Me
• I run Voltamp Media Inc., a 1-man web-dev
shop
• PHP-literate since 2002
• CodeIgniter since 2005 (1.6 whenever that
was)
• Bitten by the TDD bug around 2006
• Met Hudson/Jenkins in 2011
The Tools
• Jenkins - http://jenkins-ci.org
– Continuous Integration Tool
– Basic install is a quick download then:
• java –jar jenkins.war
• Normal vs. LTS
– For bigger installations, its recommended to run within a
java container, like Tomcat.
• PHPUnit – http://phpqatools.org
– A set of QA tools
– Installation is via PEAR
• Selenium – http://seleniumhq.org/
– java -jar selenium-server-standalone-2.31.0.jar
Getting Started
• Open a browser to:
– http://localhost:8080
Managing Jenkins
• File System Location
– Config files
– Project build areas
– Manage plugins
• Start from here - http://jenkins-php.org/
• Get the plugins
Static Code Analysis Plug-ins
Clover PHP Plugin
Plot plugin
DRY Plugin
Checkstyle Plugin
PMD Plugin
Git Plugin
HTML Publisher Plugin
xUnit Plugin
The First Job
• Each job must be configured!
– Source Code – how to get the code
– Build triggers (poll SCM, commit hooks)
– Build Steps
• Scripts (very limited environment)
• Maven
• Ant – see http://jenkins-php.org/ for yours!
– Post Build Steps
• Plots, reports
The ANT Script
• This is auto-generated,
then modified as
needed
• Test by running:
% ant /path/to/build.xml
• More at
http://ant.apache.or
g
The PHPUnit Script
• This is auto-generated, then modified as needed too
• Test by running: % phpunit
PHPUnit Tips and Tricks - fixtures
• YAML files can be used within a fixture
PHPUnit Tips and Tricks – data
providers
• YAML files can
be used as a
data provider
too
– Calls the provider
(returns an array)
– For each row it calls the
test
• The YAML is
different!
PHPUnit Tips and Tricks – Exceptions
• Test your exceptions!
• Check exception class and code
Bonus! PHPUnit and Selenium
• Make Jenkins drive PHPUnit drive Selenium!
My Issues - controller
• My current projects use CodeIgniter. CIUnit
makes using PHPUnit and CI better, but setup
is painful.
– End case of parent controller
• Correct parent class in setUp, but not in the
testMethod!
• MY_Controller vs. Controller
– $this->CI = set_controller('MY_Controller');
My Issues - Selenium
• Selenium has matured quite a bit, but
documentation and support is still very lean.
• PHPUnit’s Selenium2 class is much better, but still
leaves much to be desired.
– Click() does not wait for the page to load after a form
submission. Selenese supported clickandwait(), but I
can’t find documentation…

Mocks
Dependency Injection
Code Coverage
DRY-er!
More Integration coverage with Selenium
Exclude External Libraries in analysis || fix
them!
• Better TDD / BDD
