例: 打开百度首页 ,进行截图
package com.example.tests;
import java.io.File;
import org.apache.commons.io.FileUtils;
import org.junit.*;
import org.openqa.selenium.*;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class Selenium2 {
@Test
public void testTakesScreenshot() {
WebDriver driver = new InternetExplorerDriver();
driver.get("http://www.baidu.com");
try {
File srcFile = ((TakesScreenshot)driver).
getScreenshotAs(OutputType.FILE);
FileUtils.copyFile
(srcFile,new File("d:\screenshot.png"));
} catch (Exception e) {
e.printStackTrace();
}
driver.close();
}
}
  TakesScreenshot接口提供了getScreenshotAs()方法来捕捉屏幕。上面的例子中,我们指定了OutputType.FILE作为参数传递给getScreenshoAs()方法,告诉它将截取的屏幕以文件形式返回。
  如果使用的是RemoteWebDriver() ,则方法应该如下
  首先启动selenium java -jar selenium-server-standalone-2.25.0.jar
package com.example.tests;
import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.commons.io.FileUtils;
import org.junit.*;
import org.openqa.selenium.*;
import org.openqa.selenium.remote.*;
public class Selenium2 {
@Test
public void testRemoteWebDriverScreenShot() {
//指定使用的浏览器
DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
WebDriver driver = null;
try {
driver = new RemoteWebDriver( //我使用localhost来测试
new URL("http://localhost:4444/wd/hub"), capability);
} catch (MalformedURLException e) {
e.printStackTrace();
}
driver.get("http://www.sina.com.cn");
//对远程系统进行截图
driver = new Augmenter().augment(driver);
File scrFile =
((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
try {
FileUtils.copyFile(scrFile, new File("D:\screenshot.png"));
} catch (IOException e) {
e.printStackTrace();
}
}
}
