selenium不会遍历所有凭据，而是在线程“ main” org.openqa.selenium.NoSuchElementException中给出异常：

Question

当我尝试使用循环结构使网站自动化时，第一次迭代会运行，但是第二次迭代不会并给出.NoSuchElementException错误

我已经尝试过不带循环地输入凭据，仍然是同样的问题，当页面在第一次迭代后注销时，无法找到Webelements。我已经检查了它们，它们仍然相同，不是动态的

公共静态无效TestTitle（）引发异常{

            //compare page title and profile name

                System.out.println("Passed");
            } else {
                System.out.println("Failed");
            }

            //goes to the profile and logs out from the app
            driver.findElement(By.xpath("//*[@id=\"user-menu\"]/a")).click();
            driver.findElement(By.linkText("Logout")).click();
            //clears the login credentials from previous login
            driver.findElement(By.id("prependedInput")).clear();
            driver.findElement(By.id("prependedInput2")).clear();
            Thread.sleep(2000);

    }
}

我希望我的循环有效，通过输入网站凭据而不是注销来登录网站，然后输入相同网站的下一个凭据并注销
