嗨，我正在使用以下内容来检索警报消息数据，但它失败了

Alert alert = driver.switchTo().alert();
        String ss1=alert.getText();

它显示以下错误消息。

Popup present/Not : true

       did not provide any stacktrace information)

基于此在您的堆栈跟踪中：

    org.openqa.selenium.NoAlertPresentException: No alert is present (WARNING: The server did not provide any stacktrace information)

Selenium 认为不存在弹出窗口，您可能需要等待它出现：

    WebDriverWait wait = new WebDriverWait(driver, 15, 100)
    wait.until(ExpectedConditions.alertIsPresent())

上面的代码片段将使 selenium 等待最多 15 秒，以便每隔 100 毫秒检查一次警报是否出现。
