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);

    }

}
