This document provides code examples for handling various events in Selenium WebDriver tests, including: framing and iframes using switchTo().frame(); handling multiple windows by switching between them; accepting, dismissing, and entering text into alerts; dragging and dropping elements; performing mouse hover events; and taking screenshots on failure to capture errors.

1. Selenium Web Driver Code to handle the following events
How to handle Frames, iFrames:
Frames Code:
driver.switchTo().frame("id"); (Where id was the frame id)
iFrame Code:
WebElement iFrame= driver.findElement(By.(“id”)); (Where id was the
iframe id)
driver.switchTo().frame(iFrame);
How to handle Multiple windows:
Multiple windows Code:
for(String winHandle : driver.getWindowHandles())
{
driver.switchTo().window(winHandle);
}
driver.manage().window().maximize();
Code for the operations held in new window
String winHandleBefore = "Page Title for parent window";
driver.switchTo().window(winHandleBefore);

2. How to handle Alerts:
Alert Accept Code:
Alert al=d.switchTo().alert();
String s=al.getText();
assertEquals("Expected value in the alert",s);
al.accept();
Alert Accept Code: For confirmation alerts with ok and cancel buttons
For Alert with click ‘ok’ was same as above
For Alert with click ‘Cancel’ button below was the code:
Alert al=d.switchTo().alert();
String s=al.getText();
assertEquals("Expected value in the alert",s);
al.dismiss();
Insert values in alerts:
Alert al=d.switchTo().alert();
String s=al.getText();
assertEquals("Expected value in the alert",s);
al.sendKeys(“Text”);
al.accept();
How to handle Drag & Drop:
WebElement draggable = driver.findElement(By.id("id"));
WebElement droppable = driver.findElement(By.id("id"));
new Actions(driver).dragAndDrop(draggable, droppable).build().perform();
How to handle Mouse over events:
Actions builder = new Actions(d);
WebElement tagElement = d.findElement(By.id("id"));
builder.moveToElement(tagElement).build().perform();
tagElement.click();

3. Screenshots on Failure:
try
{
Code
}
catch(Exception e){
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
String k="C:eclipseScreenshotsMagError.png";
FileUtils.copyFile(scrFile, new File(k));
}
