HISTORY OF DRUPAL TESTING
Drupal Testing: D6 core – Simpletest Application specific testing - Manual Tests - Written test cases – Word documents - The spreadsheet of pain. (Checklist)
Challenges -
Testing different browsers Reproducible results Providing a record Doesn’t test integration with 3rd party API (backend functionality)
CONTINUOUS INTEGRATION:
Continuous Integration (CI) implements continuous processes of applying quality control — small pieces of effort, applied frequently. Continuous integration aims to improve the quality of software, and to reduce the time taken to deliver it, by replacing the traditional practice of applying quality control after completing all development. Continuous Integration emerged in the Extreme Programming (XP) community, and XP advocates Martin Fowler and Kent Beck first wrote about continuous integration circa 1999.

HACKATHON TEAM :
Five. Striving as one. Driven by a passion for continuous automated quality control.

HACKATHON OBJECTIVE:
Develop, deploy, demonstrate, and identify challenges of making using ci infrastructure to implement acceptance tests (unit tests, selenium) on one existing site.
TECHNICAL DETAILS
phpqatools.org
provisions servers with testing components
admin gui to trigger test suites, or view reports
code metrics
user acceptance
Necessary components
•For necessary components and installation instructions, go to:
•Phing Drupal Template • http://reload.github.com/phing-drupal-template/ • Jenkins Drupal Template • http://reload.github.com/jenkins-drupal-template •Phing Drupal Template with User Acceptance Test • http://github.com/promet/phing-drupal-template • In addition for phing-drupal-template with user acceptance test, you need to install additional pear libraries
• For more instructions, http://phpqatools.org/
Installing Infrastructure
Initial assumption: your server has several initial software already 1. Go to https://github.com/promet/phing-drupal-template 2. Three files that you need to use to install infrastructure 3. Put in on your site Drupal root 4. If you want to override it, build.properties 5. Customize variables
EXAMPLE TEST SUITE FOR SITE SUPPORT
Jenkins: Scheduled 1AM User
Acceptance Test Jenkins: Clone
Production to Test
PHING: Autodiscover the Selenium test
PHING: Selenium Config Upload
Done
Jenkins: If errors found, notify stakeholders
PHING: Report Generated
Jenkins & PHING: User Acceptance PHPUnit +
Selenium
PHING: Trigger each Selenium test and generate report
PHING: PHPUnit Configuration Load
PHING: Trigger each PHPUnit Test and generate report
PHING: Autodiscover the PHPUnit test

(ability to use Drupal API)
What is Selenium?
•Selenium automates browsers. That's it. What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
•Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.
• Goes through every page • Makes sure header, footer, logos, etc • All branding elements in place
Functional Test PHPUnit
• Project Airbox • Checkout process that involves passing customer information to third party
banking API, passes back customer ID • Months after completion, API changes broke the application
• PHPUnit figures out how and where the problem is • More importantly, is there a problem?
• Major time saver for detective work • -- bootstrap option to make use of forked upal without SUT • https://github.com/chriscalip/upal • http://drupal.org/node/1567500 • actually installs a complete Drupal site like the regular Drupal installer for every test
being executed, using a random database prefix and some logic baked into Drupal's (regular runtime) core that re-routes all HTTP requests originating from WebTestBase into the "child site under test" (the db-prefixed one). Based on that, every test is able to specify additional modules to install into that child site, in order to test various combinations of modules and configuration and content/data and user input and
