Selenium - IE 8 - 无法找到包含链接文本的元素

在Selenium测试中（使用版本2.40.0），我无法使用Internet Explorer 8远程查找包含链接文本的元素。它适用于Chrome。Selenium - IE 8 - 无法找到包含链接文本的元素

这里有一个公共网站（groovy）样本。

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() 
    } 

}

这是登录

编辑 我想在家里和它的工作。但在办公室，问题持续存在。可能受IE影响的网络设置，Windows域等？

我认为你的编辑可能是正确的。

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

  • 在IE 7或更高版本的Windows Vista或Windows 7，则必须为每个区是设置保护模式设置相同的价值。该值可以打开或关闭，只要每个区域的值相同即可。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，在标签为“启用保护模式”的选项卡底部会出现一个复选框。 此外，对于IE 10及更高版本，必须禁用“增强保护模式”。该选项位于“Internet选项”对话框的“高级”选项卡中。

  • 必须将浏览器缩放级别设置为100％，以便可以将原生鼠标事件设置为正确的坐标。

  • 仅适用于IE 11，您需要在目标计算机上设置注册表项，以便驱动程序可以维护与其创建的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密钥是HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ Main \ FeatureControl \ FEATURE_BFCACHE。对于64位Windows安装，密钥为HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ Internet Explorer \ Main \ FeatureControl \ FEATURE_BFCACHE。请注意，FEATURE_BFCACHE子键可能存在也可能不存在，如果不存在则应该创建。重要提示：这里面的关键，创建0

我的猜测是，你的问题是与保护模式值名为iexplore.exe的DWORD值。

这真的是一个棘手的！ – banterCZ

硒等待链接在页面上只显示285毫秒。您可以尝试使用implicit or explicit等待，等待足够长的时间以确保页面加载后该元素是否存在。

并确保Firmy是您的锚标记中存在的确切单词，即使有额外的空间它也会抛出Nosuchelement异常。如果不确定，您可以使用PartialLinkText。

这是使用显式的等待：

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

这将等待30秒的元素是可见的。

链接就在那里，这就是为什么我提到公共网页。我认为，问题可能是IE版本或代理。我必须跟踪原因。 – banterCZ
