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"));
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
