嗨，我使用下面的檢索警報消息的數據，但它失敗硒如何獲得警報警報消息

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

它顯示波紋管的錯誤消息。

在提供很少的信息時幫助不大，但是，如果您試圖在顯示警報時在您的硒腳本中獲取任何元素，那麼您的警報將消失並且出現此錯誤。 – Amit 2013-04-29 07:36:05

基於這個在您的堆棧跟蹤：

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

硒不認爲一個彈出窗口目前，您可能想等待它出現：

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

上面的代碼片段會讓硒等待長達15秒，以便警報每100毫秒檢查一次以查看它是否已經出現。

你到底在哪裏放這個片段？在初始化警報警報之前還是之前？ – ERJAN 2015-02-20 06:45:26

您需要在等待它出現之前觸發警報。 – Ardesco 2015-02-21 09:31:08
