9. WebDriver
“Best fit” language
Clean & Object Oriented API
HtmlUnitDriver
Java bindings

10. Selenium 2
- IDE
- Web Driver
Bindings : Java, C#, Python, Ruby
WebDriver API
Simplified Architecture Selenium Server NOT needed *
- Grid 2

11. Selenium Server
Replicate Selenium RC functionalities
Selenium Grid 2

12. First steps
Java / C# bindings
Selenium Server
Android APK
http://code.google.com/p/selenium/downloads/list
Chrome Driver
http://code.google.com/p/chromium/downloads/list
Ruby
gem install selenium-webdriver
Python
pip install selenium / easy_install selenium

13. Let’s code!

14. Locator Strategies
• Id
webDriver.findElement(By.id("logo"));
• Name
webDriver.findElement(By.name("q"));
• Tag Name
webDriver.findElement(By.tagName("H1"));
• Class name
webDriver.findElements(By.className("sponsor_logos"));
• CSS Selector
webDriver.findElement(By.cssSelector("section#sponsor>p"));
• XPath
webDriver.findElement(By.xpath("//section[@id=‘miniconfs’]/a[2]"));
• Link Text
webDriver.findElements(By.linkText("About"));
• Partial Link Text
webDriver.findElement(By.partialLinkText("visitcanberra"));

15. Page interactions
webElement.click()
webElement.sendKeys(...)
webElement.submit()
Actions class Mouse Events / Drag and Drop

16. AJAX applications
DOM Elements loaded asynchronously
a) Polling the DOM for n seconds
webDriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS); (Java)
webDriver.manage.timeouts.implicit_wait = 30 (Ruby)
webDriver.implicit_wait(30) (Python)
b) Wait until condition occurs
ExpectedCondition / WebDriverWait

17. Testing style and executing JS
Testing CSS properties
webElement.getCssValue(“height”);
webElement.getCssValue(“background-image”);
Javascript execution
JavascriptExecutor js = (JavascriptExecutor) webDriver;
Long value = (Long) js.executeScript("return window.scrollY");

18. TargetLocator and Navigation Interfaces
TargetLocator Frames and Popup Dialogs
TargetLocator target = webDriver.switchTo();
WebElement element = target.frame(“name”)
Alert alert = target.alert();
Navigation Browser buttons emulation
Navigation nav = webDriver.navigate();
nav.back(); / nav.forward(); nav.to(“url”);

19. Migrating from Selenium 1
Selenium selenium = new WebDriverBackedSelenium(webDriver,
“http://osdc.com.au”);
selenium.open("http://osdc.com.au");
selenium.click("id=follow_twitter");
selenium.waitForPageToLoad("10000");
WebDriver webDriver = ((WebDriverBackedSelenium)
selenium).getUnderlyingWebDriver();

20. Page Object Pattern / PageFactory
Pages as Objects
Separation between DOM and services in a Page
WebDriver API not exposed
PageFactory class to easily instantiate a Page Object

21. Selenium Grid 2
Starting Hub
java -jar selenium-server-standalone-2.9.0.jar -role hub
Starting WebDriver Node
java -jar selenium-server-standalone-2.9.0.jar -role webdriver -
