71) How to handle frames in Selenium WebDriver?
Select a frame by its (zero-based) index.
driver.switchTo().frame(int arg0);

• Select a frame using its previously located WebElement.

       driver.switchTo().frame(WebElement frameElement);

• Locating iframe using tagName

       driver.switchTo().frame(driver.findElements(By.tagName(“iframe”).get(0));

• Switch to the frame by Name

       driver.switchTo().frame("iframe1");

72) What is the difference between driver.close() and driver.quit command?

• close(): WebDriver’s close() method closes the web browser window that is being currently accessed by the WebDriver. The command neither requires any parameter nor does is return any value.

• quit(): quit() method closes down all the windows that the program has opened. Same as close() method, the command neither requires any parameter nor does is return any value.

73) How to handle web based alerts in Selenium WebDriver?
There are the four methods that we would be using along with the Alert interface.

• void dismiss():- The accept() method clicks on the “Cancel” button as soon as the pop up window appears.
• void accept():- The accept() method clicks on the “Ok” button as soon as the pop up window appears.
• String getText():- The getText() method returns the text displayed on the alert box.
• void sendKeys(String stringToSend):- The sendKeys() method enters the specified string pattern into the alert box.

Syntax:
// accepting javascript alert 
                Alert alert = driver.switchTo().alert();
                alert.accept();
