How to count the number of frames in a page in Selenium?

We can count the number of frames in Selenium by the methods listed below −

• With the help of List<WebElement> with tagname frame/iframe.

• With the help of a Javascript executor.

Example

With tagname.

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import java.util.List;
public class FrameCount{
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver",       "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url =
      "http://the-internet.herokuapp.com/nested_frames";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      //By finding list of the web elements using frame or iframe tag
      List<WebElement> f = driver.findElements(By.tagName("frame"));
      System.out.println("Total number " + f.size());
      driver.quit();
   }
}

Example

With Javascript Executor.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.JavascriptExecutor;
import java.util.concurrent.TimeUnit;
public class FrameCountJS{
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = "http://the-internet.herokuapp.com/nested_frames";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      //Javascript executor script to get the window length
      JavascriptExecutor exe = (JavascriptExecutor) driver;
      int f = Integer.parseInt(exe.executeScript("return window.length").toString());
      System.out.println("No. of iframes on the page are " + f);
      driver.quit();
   }
}
