How to wait for iFrames to load completely in Selenium webdriver?

We can wait for the iframe to load completely with Selenium webdriver.First of all we need to identify the iframe with the help iframe id, name, number or webelement. Then we shall use the explicit wait concept in synchronization to wait for the iframe to load.

We need to import org.openqa.selenium.support.ui.ExpectedConditions and import org.openqa.selenium.support.ui.WebDriverWait to incorporate expected conditions and WebDriverWait class. We will wait for the iframe to be loaded with the condition frameToBeAvailableAndSwitchToIt.

Let us see an html document of a frame.

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.openqa.selenium.support.ui.ExpectedConditions;

public class FrameLoadWait{
   public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver","C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      driver.manage().timeouts().implicitlyWait(8, TimeUnit.SECONDS);
      driver.get("https://the-internet.herokuapp.com/nested_frames");
      // frame load explicit condition
      WebDriverWait w = new WebDriverWait(driver, 5);    
      w.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("frame-bottom"));
      // identify element inside frame
      WebElement p=driver.findElement(By.cssSelector("body"));
      System.out.println("Text inside frame is: " + p.getText());
      driver.close();
   }
}

Output
