Handling Dynamic Frame Elements Using WebDriver

We can switch to frame using driver.switchToFrame(); statement. We can use Frame Element or ID or Index to switch. But what if the frame is dynamic? Dynamic in index and dynamic in attributes or if it doesn't have any attributes.

We can use its child element to find the frame. Here I have given a solution to switch to any frame in page using its child element locator. A frame which is having at least one unique element can be switched using this technique.

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class FindingFrameElementUsingChildElement {

 public static void main(String[] args) {
  System.setProperty("webdriver.chrome.driver", "F:\\SeleniumSoftware\\BrowserDrivers\\chromedriver.exe");
  WebDriver driver = new ChromeDriver();

  // Maximize browser
  driver.manage().window().maximize();

  // setup page load timeout
  driver.manage().timeouts().pageLoadTimeout(15, TimeUnit.SECONDS);

  // element wait time
  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

  // open url
  driver.get("file:///C:/Users/envy/Desktop/FindFrame/Index.html");
  
  //specify child element locator
  By childElmLocator = By.id("demotextfrm");
  
  //If child elment found this will switch to that frame and enters text
  if(switchToFrameByUsingChild(driver, childElmLocator)) {
   driver.findElement(childElmLocator).sendKeys("test");
   System.out.println("Switched to Frame where child exist");
  }else {
   System.out.println("Frame not found.");
  }  
  
 }

 public static boolean switchToFrameByUsingChild(WebDriver driver, By childElmLocator) {
  driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
  //get all frame element from the page
  List frameElems = getAllFrames(driver);
  
   //use forloop to navigate switch one by one frame
   for (int frmIndex = 0; frmIndex < frameElems.size(); frmIndex++) {
    //switch to frame
    driver.switchTo().frame(frameElems.get(frmIndex));
    //verify element existance in frame
    if (driver.findElements(childElmLocator).size() > 0) {
     //if exist exit from method     
     return true;
     //if not exist verify that any frames exist
    } else if (getAllFrames(driver).size() > 0) {
     //call the switchToChildFrameByChild method
     //this verify element existance in child frames 
     if(switchToChildFrameByChild(driver, childElmLocator)) {
      //if exist in child element exit from method     
      return true;
     }else {
      //switch to main page if element not exist in frame and child frames
      driver.switchTo().defaultContent();
     }
    }else {
     //switch to main page if element not exist in frame
     driver.switchTo().defaultContent();
    }
   }
  return false;

 private static List getAllFrames(WebDriver driver) {
  //to get all frame elements that are created using frame and iframe tags
  List iFrmLst = driver.findElements(By.tagName("iframe"));
  List frmLst = driver.findElements(By.tagName("frame"));
  List totalFrms = new ArrayList();
  totalFrms.addAll(iFrmLst);
  totalFrms.addAll(frmLst);
  return totalFrms;
 }

    } else if (getAllFrames(driver).size() > 0) {

     } else {
      //switch to parent frame as element not exist
