Consider below example about switch to frames using index value and while execute the script giving TypeError can’t access dead object error message on console.

Example:

public static void main(String[] args) throws InterruptedException {

System.setProperty("webdriver.gecko.driver", "D:/NTTA_Automation/ChasePayment/driver/geckodriver.exe");
System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true");
System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, "/dev/null");

driver = new FirefoxDriver();
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.get("https://xxxxx.com");
Thread.sleep(5000);
driver.switchTo().frame(0);
driver.findElement(By.id("name")).clear();
driver.findElement(By.id("name")).sendKeys("tollplus");
driver.findElement(By.id("ccNumber")).clear();
driver.findElement(By.id("ccNumber")).sendKeys("5454545454");
driver.findElement(By.id("CVV2")).clear();
driver.findElement(By.id("CVV2")).sendKeys("123");
Thread.sleep(1000);
new Select(driver.findElement(By.id("expMonth"))).selectByVisibleText("12");
Thread.sleep(1000);
driver.findElement(By.id("Button")).click();
Thread.sleep(5000);

String getText = driver.findElement(By.xpath("//h2[text()='Success']")).getText();

if (getText.equals("Success")) {
system.out.println("Message Success is displaying on screen");

driver.quit();
} else {
System.out.println("Message Success is not displaying on screen");

}

}
}

Solution : TypeError can’t access dead object

After switching into “driver.switchTo().frame(0)”; any frame ,we need to come back to default content of our respective open browser page,add below line before getText method as below.

public static void main(String[] args) throws InterruptedException {

System.setProperty("webdriver.gecko.driver", "D:/NTTA_Automation/ChasePayment/driver/geckodriver.exe");
System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true");
System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, "/dev/null");

driver = new FirefoxDriver();
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.get("https://xxxxx.com");
Thread.sleep(5000);
driver.switchTo().frame(0);
driver.findElement(By.id("name")).clear();
driver.findElement(By.id("name")).sendKeys("tollplus");
driver.findElement(By.id("ccNumber")).clear();
driver.findElement(By.id("ccNumber")).sendKeys("5454545454");
driver.findElement(By.id("CVV2")).clear();
driver.findElement(By.id("CVV2")).sendKeys("123");
Thread.sleep(1000);
new Select(driver.findElement(By.id("expMonth"))).selectByVisibleText("12");
Thread.sleep(1000);
driver.findElement(By.id("Button")).click();
Thread.sleep(5000);

//Add below line to switch back to default content to get access to all the objects.
driver.switchTo.defaultContent();

String getText = driver.findElement(By.xpath("//h2[text()='Success']")).getText();

if (getText.equals("Success")) {
system.out.println("Message Success is displaying on screen");

driver.quit();
} else {
System.out.println("Message Success is not displaying on screen");
driver.quit();
}

}
}
