What is Selenium?
Selenium IDE
Selenium RC
Selenium Grid
Selenium 2 (Webdriver)

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

Selenium2 and Drupal
Simpletest. Change user agent headers.
Support for Firefox and Chrome
http://drupal.org/project/selenium

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...)

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

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"]

Important notes
Selenium is for automating of manual testing
Can't interact with hidden elements
Sometimes browser is too fast. Remember to wait till javascript finishes its work.
Some differences in API between browsers (Chrome can't upload files, difference in work with selectboxes)

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

Drupal core tests
autocomplete
collapse
machine-name
states
tabledrag
tableheader
tableselect
textarea
vertical-tabs
upload
