Ruby

time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path

Java (Robot Framework)

我使用这种方法进行截图。

void takeScreenShotMethod(){
    try{
        Thread.sleep(10000)
        BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
        ImageIO.write(image, "jpg", new File("./target/surefire-reports/screenshot.jpg"));
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

你可以在任何需要的地方使用这种方法。

Java

我无法得到可接受的答案，但根据当前的WebDriver文档，以下内容对我来说在OS X v10.9 (Mavericks)上的Java 7工作得很好:

import java.io.File;
import java.net.URL;

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class Testing {

   public void myTest() throws Exception {
       WebDriver driver = new RemoteWebDriver(
               new URL("http://localhost:4444/wd/hub"),
               DesiredCapabilities.firefox());

       driver.get("http://www.google.com");

       // RemoteWebDriver does not implement the TakesScreenshot class
       // if the driver does have the Capabilities to take a screenshot
       // then Augmenter will add the TakesScreenshot methods to the instance
       WebDriver augmentedDriver = new Augmenter().augment(driver);
       File screenshot = ((TakesScreenshot)augmentedDriver).
               getScreenshotAs(OutputType.FILE);
   }
}

File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage originalImage = ImageIO.read(scrFile);
//int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
BufferedImage resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");

c#代码

IWebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((ITakesScreenshot)driver).GetScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

/**
 * Take a screenshot and move to the given folder location.
 *
 * @param driver
 * @param folderLocation
 * @return screenShotFilePath
 */
public static String captureScreenshot(WebDriver driver, String folderLocation) {

    // Variable to store screenshot's file path.
    String screenShotFilePath = null;

    // Generate unique id for screen shot name.
    String uniqueId = UUID.randomUUID().toString().substring(31);

    if (driver != null) {

        // Generate screenshot as a file
        File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

        // New screenshot file path with having file name
        screenShotFilePath = folderLocation + File.separator + uniqueId + ".png";

        // Move file to the destination location.
        FileUtils.moveFile(scrFile, new File(screenShotFilePath));
    }

    return screenShotFilePath;
}
