1. Automated UI testing.
Selenium

2. Gold Sponsor of
DrupalCamp Kyiv 2011

3. Silver Sponsors of

4. Plan

What is Selenium?

Selenium IDE, RC, Webdriver

Integration to Drupal

Tests API, locators, examples

Future

5. What is Selenium?

Selenium IDE

Selenium RC

Selenium Grid

Selenium 2 (Webdriver)

6. Selenium IDE

Addon to Firefox

Easy to start using

Can record tests in PHP

Demo

7. Selenium RC

Run in multiple browsers in Virtual Boxes

Runs tests via Javascript

8. Selenium RC

To install Selenium RC download java server
from http://seleniumhq.org/download

Run Selenium IDE tests via PHPUnit

Ubuntu: apt-get install phpunit

If php 5.2 make a preference for karmic like for
php

Demo

9. Selenium 2 Webdriver

Communicate with browsers in 'native' way via
drivers

Not limited to javascripts. For example: upload
files, work with popups, iframes etc.

Support for a lot of browsers including mobile
phone browsers

PHPUnit libraries:
https://github.com/chibimagic/WebDriver-PHP

10. Selenium2 Webdriver and Drupal

How to integrate to simpletest

In order to get into sandbox we need to set
headers

This is possible with Firefox only (send custom
profile to Selenium)

http://drupal.org/project/selenium

Demo

11. Drupal tests API

Main class DrupalSeleniumWebTestCase

Init driver as connection to Selenium server

Already implemented methods:

drupalOpenUrl, drupalLogin, drupalLogout,
verboseScreenshot ...

class SeleniumWebElement (sendKeys, click,
submit, getText...)

12. Selenium 2 locators
css, id, name, class, link, xpath

13. XPath vs CSS locators
Selenium RC has sizzle
Webdriver uses native browsers CSS selectors.
CSS selectors are faster
XPath can go up
Example:
id('user1')/../../td[@class="actions"]/a[@class="delete-user"]

14. Drag and drop example

15. Run tests on headless server

Key tool: Xvfb – X11 server that performs all graphical
operations in memory, not showing any screen output
(http://en.wikipedia.org/wiki/Xvfb).

Before we start Selenium server we need to start Xvfb.

Run tests from shell:
sudo -u www-data php ./scripts/run-tests.sh --url http://URL --class
SeleniumTestExample

16. Future

Implement methods from DrupalWebTestCase

Start using Selenium in testing contrib modules
and core (module draggableviews already have
one selenium test)
