WebDriver Explorer菜单滚动

时间：2013-09-03 17:37:10

标签： java webdriver selenium-webdriver

我们的网络应用程序UI基于GXT框架（GWT + EXT JS）并具有资源管理器（树）类菜单。 我想向下滚动以到达资源管理器中的树节点。这是我试过的

enter image description here 

@Test

public void test() {

    logger.info("*************** Started Create Template ******************");

    String nodeElement = //span[@class='x-tree3-node-text'][contains(text(),'QE Auto Template585 [1]')]";
    WebElement treeNode = driver.findElement(By.xpath(nodeElement));        

    treeNode.click();       

}

我仍然得到'NoSuchElementException'，即使这是DOM中存在的元素 任何指针？

我正在使用selenium v​​2.35 / firefox v23

答案 0 :(得分：1)

在您尝试查找这些元素之前，这些元素可能尚未在DOM中完成加载。

您可以尝试等待预期的条件presenceOfAllElementsLocatedBy：

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver).withTimeout(15L, TimeUnit.SECONDS).pollingEvery(1, TimeUnit.SECONDS);

List<WebElement> treeNodes = wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.className("x-tree3-node-text")));

答案 1 :(得分：0)

只有firefox 23支持原生事件。我认为FF 28还不支持。
