Selenium/PHP/Test framework deployment

This is a project to get an integrated testing framework in place.
 * Markus Glaser added initial Selenium testing support to the repository,
 * Ryan Lane has been building a cluster,
 * Priyanka Dhanda has been refining the Selenium configuration
 * Mark Hershberger integrating with CruiseControl to run both Selenium and PHPUnit tests
 * Michelle Knight has been recording Selenium tests

Status: Permanent hiatus
Update 2011-07-01: We sort of set up Selenium Grid, which automatically runs Selenium tests in different virtual environments (each with a different browser/OS etc.).

But most contributors ignored Selenium; they don't find its output useful. And Selenium Grid is an ops headache (it's a chore to maintain the VMs, and sometimes a Selenium Grid test failure actually indicates a Grid or virtual machine problem rather than a broken test!). Also, Selenium Grid's scope was limited: It remotely controls browsers in the VMs, so unless Selenium supported an OS and browser, it couldn't be part of the 'grid'.

WMF shut down their Selenium Grid VMs a few weeks ago in favor of TestSwarm. Sumanah 18:56, 1 July 2011 (UTC)

Feature justification
Currently, we do not have a lot of formal testing of MediaWiki, except for some usability work that Wikimedia Foundation has worked with Calcey to provide. Automated testing has also been lacking.

Selenium provides a means of doing automated system testing. This work would be complementary to work on Apache Continuum, which can provide us the means of continuously running Selenium tests, and with PHPUnit, which provides us with a framework for unit testing.

 * Documentation about the existing Selenium Framework (in progress)

Schedule
Milestones correspond to status meetings:
 * Sept 17 - send out proposed configuration (with prototype code)
 * Sept 24 - more or less working dynamic configuration, with a test or two actually using it
 * Oct 1 - dynamic config problem solved, and a couple of extension tests, initial test runs on the grid
 * Oct 8 - running better on the grid
 * Oct 15 - running smoothly on the grid
 * Oct 22 - finished

Automation work done by the Calcey team
Calcey has worked on basic automation of Wikimedia usability, using Selenium.

Test scripts are recorded using Selenium IDE 1.0.7 and converted to PHP. Test scripts were implemented such that data and code can be maintained individually and are reusable.

The automation suite can be found on the <> location. Recorded test scripts can be executed using the NetBeans IDE 6.8 which was integrated with PHP Unit and Selenium module for PHP.

Automated scripts can be run individually as separate scripts or complete test suite can be run at once. Test results will be generated with status of passed or failed for each and every test scenario available in the test scripts.
