是否可以使用Selenium WebDriver进行截图?

(注:不含硒遥控器)

Java

是的,这是可能的。下面以Java为例:

WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)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"));

我使用下面的c#代码来获取整个页面或仅一个浏览器截图

    public void screenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
            Screenshot screenshot = screen.GetScreenshot();
            screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
        }
    }

    public void fullPageScreenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            }
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
        }
    }

Java

这里似乎没有-在Java中截取一个特定元素的截图:

public void takeScreenshotElement(WebElement element) throws IOException {
    WrapsDriver wrapsDriver = (WrapsDriver) element;
    File screenshot = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
    Rectangle rectangle = new Rectangle(element.getSize().width, element.getSize().height);
    Point location = element.getLocation();
    BufferedImage bufferedImage = ImageIO.read(screenshot);
    BufferedImage destImage = bufferedImage.getSubimage(location.x, location.y, rectangle.width, rectangle.height);
    ImageIO.write(destImage, "png", screenshot);
    File file = new File("//path//to");
    FileUtils.copyFile(screenshot, file);
}

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);
   }
}

是的,可以使用Selenium WebDriver对网页进行快照。

WebDriver API提供的getScreenshotAs()方法为我们做了这项工作。

语法:getScreenshotAs(OutputType<X> target)

返回类型:X

参数:target—查看OutputType提供的选项

适用性:不特定于任何DOM元素

例子:

    TakesScreenshot screenshot = (TakesScreenshot) driver;
    File file = screenshot.getScreenshotAs(OutputType.FILE);

有关详细信息,请参阅下面的工作代码片段。

    public class TakeScreenShotDemo {

        public static void main(String[] args) {
            WebDriver driver = new FirefoxDriver();
            driver.manage().window().maximize();
            driver.get(“http: //www.google.com”);

            TakesScreenshot screenshot = (TakesScreenshot) driver;

            File file = screenshot.getScreenshotAs(OutputType.FILE);

            // Creating a destination file
            File destination = new File(“newFilePath(e.g.: C: \\Folder\\ Desktop\\ snapshot.png)”);
            try {
                FileUtils.copyFile(file, destination);
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
    }

机器人框架

下面是一个使用Robot Framework和Selenium2Library的解决方案:

*** Settings ***
Library                        Selenium2Library

*** Test Cases ***
Example
    Open Browser               http://localhost:8080/index.html     firefox
    Capture Page Screenshot

这将在工作空间中保存一个截图。也可以为关键字Capture Page截图提供一个文件名来改变这种行为。
