| 捕捉屏幕截图
截图捕获功能可以帮助我们在需要在运行时抓取截图，在特别是当故障发生。随着截图的帮助和日志信息，我们将能够更好地分析结果
截图是本地执行和Selenium 网格(远程)处决配置不同。让我们来看看他们每一个例子。
本地主机执行
在下面的例子中，我们将计算百分比之后的截图。请确保给一个有效的路径，用以保存屏幕截图。
import
java.io.File;
import java.io.IOException;
import java.util.concurrent.TimeUnit;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
public class webdriverdemo
{
public static void main(String[] args) throws
IOException
{
WebDriver driver = new FirefoxDriver();
//Puts a Implicit wait, Will wait for
10 seconds before throwing exception
driver.manage().timeouts().implicitlyWait(10,
TimeUnit.SECONDS);
//Launch website
driver.navigate().to("http://www.calculator.net/");
//Maximize the browser
driver.manage().window().maximize();
// Click on Math Calculators
driver.findElement(By.xpath(".//*[@id='menu']/div[3]/a")).click();
// Click on Percent Calculators
driver.findElement(By.xpath(".//*[@id='menu']/div[4]/div[3]/a")).click();
// Enter value 10 in the first number
of the percent Calculator
driver.findElement(By.id("cpar1")).sendKeys("10");
// Enter value 50 in the second number
of the percent Calculator
driver.findElement(By.id("cpar2")).sendKeys("50");
// Click Calculate Button
driver.findElement(By.xpath(".//*[@id='content']/table/tbody/tr/td[2]/input")).click();
// Get the Result Text based on its xpath
String result = driver.findElement(By.xpath(".//*[@id='content']/p[2]/span/font/b")).getText();
File screenshot = ((TakesScreenshot)driver).getScreenshotAs
(OutputType.FILE);
FileUtils.copyFile(screenshot, new File("D:screenshotsscreenshots1.jpg"));
//Print a Log In message to the screen
System.out.println(" The Result is
" + result);
//Close the Browser.
driver.close();
}
}

输出
在执行这个脚本，截图保存在“D:screenshots”文件夹中名为'screenshots1.jpg“，如下图所示。
Selenium网格- 捕捉屏幕截图
当Selenium网格工作，我们应该确保从远程系统采取正确的截图。我们将充分利用增强的驱动程序。
例子
我们将连接到集线器Firefox的节点上执行该脚本。更多关于配置集线器和节点，请参阅Selenium网格章节。
