如何使用while循环验证WebElement是否存在

Question

我添加了这个来创建一个随机组名，现在我想验证这个组名是否存在：public String generateRandomName(int length) {    char[] chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"            .toCharArray();    StringBuilder sb = new StringBuilder();    Random random = new Random();    for (int i = 0; i < length; i++) {        char c = chars[random.nextInt(chars.length)];        sb.append(c);    }    String randomString = sb.toString();    return randomString;}这是我的while循环：public boolean validateGroupNameIsCorrect(String groupName) {    int i = 1;    WebElement NewGroupText = driver.findElement(By.xpath("//*[@id='content']/form/span["+ i + "]"));    while (true) {        if (getNewGroupText().getText().equals(groupName));        return true;        System.out.println(i);    }}
