本文介绍了一种使用Selenium WebDriver进行IE浏览器自动化测试的方法。通过创建自定义MyIEDriver类，实现了与现有浏览器会话的连接及操作。示例代码展示了如何启动IE浏览器、执行基本的搜索操作，并复用已打开的浏览器窗口。

看了 http://blog.youkuaiyun.com/wwwqjpcom/article/details/51232302 这个的文章，照葫芦画瓢，弄了一个IE版本。

MyIEDriver.java


import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Map;

public class MyIEDriver extends InternetExplorerDriver {
	public static String sid = "0277ded1-a5fa-40f6-a396-9c192049051c";
	public static String url = "http://localhost:38005";
	private Capabilities mycapabilities;

	public MyIEDriver() {
		mystartClient(url);
		mystartSession(sid);
	}

	@Override
	protected void startSession(Capabilities desiredCapabilities, Capabilities requiredCapabilities) {
	}

	@Override

	}

	protected void mystartClient(String localserver) {
		HttpCommandExecutor delegate = null;

		try {
			URL driverserver = new URL(localserver);
			delegate = new HttpCommandExecutor(driverserver);
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}

		try {
			delegate.getAddressOfRemoteServer().openConnection().connect();
			super.setCommandExecutor(delegate);
			System.out.println("Connect to the existing browser");

		} catch (IOException e) {
			System.out.println(e.getMessage());
			System.out.println("can not connect" + delegate.getAddressOfRemoteServer() + "  and  " + delegate);
		}
	}

	protected void mystartSession(String sessionID) {

		if (!sessionID.isEmpty()) {
			super.setSessionId(sessionID);

		if (returnedCapabilities == null) {
			returnedCapabilities = new DesiredCapabilities();
		}
		for (Map.Entry<String, Object> entry : rawCapabilities.entrySet()) {
			// Handle the platform later
			if (CapabilityType.PLATFORM.equals(entry.getKey())) {
				continue;
			}
			returnedCapabilities.setCapability(entry.getKey(), entry.getValue());
		}
		String platformString = (String) rawCapabilities.get(CapabilityType.PLATFORM);
		Platform platform;
		try {

			}
		} catch (IllegalArgumentException e) {

			// system property. Try to recover and parse this.
			platform = Platform.extractFromSysProperty(platformString);
		}
		returnedCapabilities.setPlatform(platform);

		this.mycapabilities = returnedCapabilities;

	}

	@Override

	}

	}

	@Override

		}

		// Escape the quote marks

	}

}

开启浏览器：

import java.net.URL;
import java.util.Set;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.HttpCommandExecutor;

public class AppTest {
	public static void main(String[] args) {
		System.setProperty("webdriver.ie.driver", "D:/auto/public/selenium/webdriver/win64/IEDriverServer.exe");

		InternetExplorerDriver driver = new InternetExplorerDriver();
		
		String sessionid = driver.getSessionId().toString();
		System.out.println("session ID --->" + sessionid);
		
		URL url = ((HttpCommandExecutor)(driver.getCommandExecutor())).getAddressOfRemoteServer();
		System.out.println("url --->" + url.toString());
		
		driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
		driver.get("http://www.google.com");
		
		
		WebElement key =driver.findElement(By.id("lst-ib"));
		key.sendKeys("abc");
		
		Set set = driver.getWindowHandles();
		
//		driver.getCommandExecutor().getAddressOfRemoteServer().toString();
	}
}

不关闭浏览器，另外一段代码复用刚开启的浏览器：

public class Apptest2 {
	public static void main(String[] args) {
		System.setProperty("webdriver.ie.driver", "D:/auto/public/selenium/webdriver/win64/IEDriverServer.exe");

		InternetExplorerDriver driver = new MyIEDriver();
//		driver.get("http://localhost:38005");

		driver.get("http://www.baidu.com");
//		driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
//		WebElement key =driver.findElement(By.id("lst-ib"));
//		key.sendKeys("g");

	}
}
