How to get total number of nested frames inside the frame

Snapshot of Frame_top with 3 nested frames:

Code:

WebElement topframe = driver.findElement(By.xpath("//frame[@name='frame-top']"));   
String frame1 =  driver.switchTo().frame(topframe).switchTo().frame("frame-left").findElement(By.xpath("//body")).getText();                
System.out.println(frame1);
List<WebElement> nestedFrames = driver.switchTo().frame(topframe).findElements(By.tagName("frame"));
System.out.println(nestedFrames.size());

On top you can see this page has nested frames inside the frame(frame_top).
Using line 1-3 I'm able to get the text of each nested frame. However I can't get number of frames inside the "Frame_top".(Line 4-5).
How do I get total number of frames inside the "frame_top"? Thanks in advance

To get total number of nested frames with in the parent <frame> you need to:

• Induce WebDriverWait for the desired frameToBeAvailableAndSwitchToIt.
• Induce WebDriverWait for the visibilityOfAllElementsLocatedBy() of the frames.
• You can use either of the following Locator Strategies:

  • Using cssSelector and tagName:

    new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("frame[name='frame-top']")));
    System.out.println(new WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.tagName("frame"))).size());
    

  • Using xpath and tagName:

    new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.xpath("//frame[@name='frame-top']")));
    System.out.println(new WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.tagName("frame"))).size());
