在 Selenium 测试（使用版本 2.40.0）中，我无法远程使用 Internet Explorer 8 找到带有链接文本的元素。它适用于 Chrome。

这里有一个公共网站的（groovy）示例。

import org.junit.Test
import org.openqa.selenium.By
import org.openqa.selenium.remote.DesiredCapabilities
import org.openqa.selenium.remote.RemoteWebDriver

class SampleIT {

    @Test
    void test() {
        def abilities = DesiredCapabilities.internetExplorer()
        def webDriver = new RemoteWebDriver(new URL("http://10.50.26.116:4444/wd/hub"), abilities)
        webDriver.get("http://www.seznam.cz")
        webDriver.findElement(By.linkText("Firmy")).click()
    }

}

这是日志

   org.openqa.selenium.NoSuchElementException: Unable to find element with link text == Firmy (WARNING: The server did not provide any stacktrace information)

编辑 我在家里试过了，它奏效了。但在办公室，问题一直存在。IE 会受到网络设置、Windows 域等的影响吗？

我认为您的编辑可能走在正确的轨道上。

从Selenium Internet Explorer wiki中，您可以看到以下所需配置：

  • 在 Windows Vista 或 Windows 7 上的 IE 7 或更高版本上，您必须将每个区域的保护模式设置设置为相同的值。该值可以打开或关闭，只要每个区域都相同。要设置保护模式设置，请从“工具”菜单中选择“Internet 选项...”，然后单击“安全”选项卡。对于每个区域，标签底部都会有一个标记为“启用保护模式”的复选框。此外，对于 IE 10 及更高版本，必须禁用“增强保护模式”。此选项位于 Internet 选项对话框的高级选项卡中。

  • 浏览器缩放级别必须设置为 100%，以便可以将本机鼠标事件设置为正确的坐标。

  • 仅对于 IE 11，您需要在目标计算机上设置一个注册表项，以便驱动程序可以保持与它创建的 Internet Explorer 实例的连接。对于 32 位 Windows 安装，您必须在注册表编辑器中检查的项是 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE。对于 64 位 Windows 安装，密钥是 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE。请注意，FEATURE_BFCACHE 子项可能存在也可能不存在，如果不存在，则应创建它。重要提示：在此键中，创建一个名为 iexplore.exe 且值为 0 的 DWORD 值。

我的猜测是您的问题与保护模式有关。

Selenium 只等待了 285 毫秒，链接在页面上可见。您可以尝试使用隐式或显式等待，这将等待足够长的时间以确保在页面加载后元素是否存在。

并确保Firmy您的锚标记中存在确切的单词，即使有额外的空格也会引发Nosuchelement异常。如果不确定可以使用PartialLinkText.

这是使用显式等待：

new WebDriverWait(driver, 30).until(ExpectedConditions.visibilityOfElementLocated(By.linkText("Firmy"))).click();

这将等待 30 秒以使元素可见。
