I would like to know all the frames available on the page, how can I get that?

We can get a list of frame names available on a page as below:

	//Make sure you are in default frame
	driver.switchTo().defaultContent();
	List framesetList=driver.findElements(By.tagName("frame"));
	if(framesetList.size()>0){
	   for(WebElement framename :framesetList){
	      System.out.println("Frame with name:" + framename.getAttribute("name")+" found.");
	      }
	}
	else {
	      System.out.println("No frame found");
	}

How can I switch WebDriver control between Frames?

If the application under test contains frames, then we need to switch the WebDriver control to that frame before interacting with the element inside the frame.

We can switch to frame either with it’s name/id or by specifying frame index.

Sample code : By using frame name

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

By index (Zero-based):

driver.switchTo().frame(1);

And to come back to default frame:

driver.switchTo().defaultContent();

How can I switch WebDriver control to new window?

To switch latest window opened use below code:

for(String winHandle : driver.getWindowHandles()){
    driver.switchTo().window(winHandle);
}

Sampe code:

 package test;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class SwithcToNewWindow {

	public static void main(String[] arg) {

		// Instantiate the FirefoxDriver
		WebDriver driver = new FirefoxDriver();

		// Visit the Selenium-WebDriver FAQ site
		driver.get("http://seleniumwebdriverfaq.tumblr.com/");

		// Print the title of the page - It should print
		// "Selenium-WebDriver FAQ's"
		System.out.println("Title of the page before - switchingTo: " + driver.getTitle());

		//Now click on RSS button; it will open in new window
		driver.findElement(By.xpath("//a[text()='RSS']")).click();

		//Switch to newly opened window -RSS and get the page titele
		for(String winHandle : driver.getWindowHandles()){
		    driver.switchTo().window(winHandle);
		}
		System.out.println("Title of the page after - switchingTo: " + driver.getTitle());

		// Close the browser window
		driver.close();

		// Quit the driver
		driver.quit();
	}
}

Why I am getting "java.lang.IllegalStateException" while instantiating Chrome driver?

Sample error log:

Exception in thread "main" java.lang.IllegalStateException: The path to the chromedriver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://code.google.com/p/chromium/downloads/list
    at com.google.common.base.Preconditions.checkState(Preconditions.java:172)
    at org.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:103)
    at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:86)
    at tests.ChromeTest.main(ChromeTest.java:29)

To solve this problem, you have to set chromedriver executable path by the “webdriver.chrome.driver” system property.

That is, in java you can set that as below:

System.setProperty("webdriver.chrome.driver","C:\path\to\<<chromedriver_win_...>>\chromedriver.exe");

// Then Instantiate the ChromeDriver
WebDriver driver = new ChromeDriver();

Note - You can download latest ChromeDriver binary from here

				// Instantiate the OperaDriver 
				WebDriver driver = new OperaDriver();

				// Visit the Selenium-WebDriver FAQ site
				driver.get("http://seleniumwebdriverfaq.tumblr.com/");

				// Print the title of the page - It should print "Selenium-WebDriver FAQ's"
				System.out.println("Title of the page is: " + driver.getTitle());
