如何在Java8中使用硒切换回父窗口

Question

我在子窗口中使用了以下代码，

driver.getWindowHandles().forEach(winHandle -> driver.switchTo().window(winHandle));

如何切换到父窗口？

Answer 1

    Set<String> ids = driver.getWindowHandles();
    Iterator<String> i = ids.iterator();
    String parentID = i.next(); //Parent Window
    while(i.hasNext())
    {
        String childID = i.next(); //Child Windows
        driver.switchTo().window(childID); // Iterating over child windows
    }

    driver.switchTo().window(parentID); //switching back to Parent window

Answer 2

int i = 0; // 0 for first window / tab
ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles());
driver.switchTo().window(tabs.get(i));
