我正在尝试将一份使用Selenium IDE编写的内部Web应用程序脚本，转移到使用Java中RemoteWebDrivers的Selenium Grid环境。
这份脚本在Chrome和Firefox上能够正常运行，但是在Internet Explorer上却不行。每次当我试图在页面中查找一个元素时，我只得到一个NoSuchElementException异常（页面本身可以正常加载）。
以下是使用维基百科页面展示相同行为的示例代码：
public class Wikipedia_test_IE {
private WebDriver driver = null;
private String baseUrl = null;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
@Before
public void setUp() throws Exception {
// DesiredCapabilities cap = DesiredCapabilities.firefox();
DesiredCapabilities cap = DesiredCapabilities.internetExplorer();
cap.setCapability(CapabilityType.VERSION, "9");
driver = new RemoteWebDriver (new URL("http://192.168.1.230:4444/wd/hub"), cap);
baseUrl = "https://en.wikipedia.org/wiki/Rosetta_%28spacecraft%29";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@Test
public void testAKTargobankTestfall1KN() throws Exception {
driver.get(baseUrl);
driver.findElement(By.linkText("space probe")).submit();
}
}
我尝试使用findElement(By.Id)和findElement(By.cssSelector)但没有效果。在页面加载和选择之间加入延迟也没有效果，使用click而不是submit也一样。我已经启用了IE驱动程序的调试日志记录，但输出并不能帮助我理解问题所在，希望有人能够提供帮助。
