java - 在 Selenium WebDriver 中执行 InternetExplorerDriver 时发生 NoSuchElementException

Question

目前，我正在开发 WebDriver 以调用 IE 浏览器来运行测试。但是当我尝试运行下面的简单示例时收到了 NoSuchElementException。

但是，如果我使用 Chrome 驱动程序或 Firefox 驱动程序，代码就可以正常工作。任何想法或想法将不胜感激。

jar :selenium-server-standalone-2.5.0.jar

代码:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public static void main(String[] args) throws InterruptedException {
  DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer();
  ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
  WebDriver driver = new InternetExplorerDriver(ieCapabilities);
  driver.get("www.google.com");
  driver.findElement(By.name("q"));
}

错误信息:

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to find element with name == q (WARNING: The server did not provide any stacktrace information)

Answer 1

您已明确避免必须设置 IE 的保护模式设置。这就是 InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS 功能设置的作用。当您删除此功能设置并设置保护模式设置时，如 project wiki 中所述, 看来问题自行解决了。
