有谁知道是否可以使用Selenium WebDriver截屏？（注：不是硒RC）

爪哇

是的，有可能。以下示例是Java语言：

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"));

蟒蛇

每个WebDriver都有一个.save_screenshot(filename)方法。因此，对于Firefox，可以这样使用：

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')

令人困惑的是，.get_screenshot_as_file(filename)还存在执行相同功能的方法。

也有以下方法：（.get_screenshot_as_base64()用于嵌入html）和.get_screenshot_as_png()（用于检索二进制数据）。

并且请注意，WebElement的.screenshot()方法工作类似，但是仅捕获所选元素。

C＃

public void TakeScreenshot()
{
    try
    {            
        Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
        ss.SaveAsFile(@"D:\Screenshots\SeleniumTestingScreenshot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        throw;
    }
}

JavaScript（Selenium-Webdriver）

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});

红宝石

require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :ie 
driver.get "https://www.google.com"   
driver.save_screenshot("./screen.png")

还有更多文件类型和选项可用，您可以在takes_screenshot.rb中查看

我解决了这个问题。您可以扩充RemoteWebDriver，以为其提供其代理驱动程序实现的所有接口：

WebDriver augmentedDriver = new Augmenter().augment(driver); 
((TakesScreenshot)augmentedDriver).getScreenshotAs(...); //works this way

PHP（PHPUnit）

使用PHPUnit_Selenium扩展版本1.2.7：

class MyTestClass extends PHPUnit_Extensions_Selenium2TestCase {
    ...
    public function screenshot($filepath) {
        $filedata = $this->currentScreenshot();
        file_put_contents($filepath, $filedata);
    }

    public function testSomething() {          
        $this->screenshot('/path/to/screenshot.png');
    }
    ...
}

C＃

public Bitmap TakeScreenshot(By by) {
    // 1. Make screenshot of all screen
    var screenshotDriver = _selenium as ITakesScreenshot;
    Screenshot screenshot = screenshotDriver.GetScreenshot();
    var bmpScreen = new Bitmap(new MemoryStream(screenshot.AsByteArray));

    // 2. Get screenshot of specific element
    IWebElement element = FindElement(by);
    var cropArea = new Rectangle(element.Location, element.Size);
    return bmpScreen.Clone(cropArea, bmpScreen.PixelFormat);
}

爪哇

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

import org.openqa.selenium.firefox.FirefoxDriver as FirefoxDriver

self.driver = FirefoxDriver()
tempfile = self.driver.getScreenshotAs(OutputType.FILE)
FileUtils.copyFile(tempfile, File("C:\\screenshot.png"))

Java（机器人框架）

我使用这种方法进行屏幕截图。

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();
    }
}

您可以在任何需要的地方使用此方法。

似乎在这里缺失-拍摄Java中特定元素的屏幕截图：

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);
}

C＃

using System;
using OpenQA.Selenium.PhantomJS;
using System.Drawing.Imaging;

namespace example.com
{
    class Program
    {
        public static PhantomJSDriver driver;

        public static void Main(string[] args)
        {
            driver = new PhantomJSDriver();
            driver.Manage().Window.Size = new System.Drawing.Size(1280, 1024);
            driver.Navigate().GoToUrl("http://www.example.com/");
            driver.GetScreenshot().SaveAsFile("screenshot.png", ImageFormat.Png);
            driver.Quit();
        }
    }
}

需要NuGetPackages：

1. PhantomJS 2.0.0
2. 硒支持2.48.2
3. Selenium.WebDriver 2.48.2

使用.NETFramework v4.5.2测试

               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);
   }

Python-Element的屏幕截图：

这是一个很老的问题，有多个答案。但是，这里似乎缺少使用Python拍摄特定Web元素的屏幕截图的功能。

位置

Web元素在页面上具有自己的位置，通常以x和y像素为单位进行度量，称为元素的（x，y）坐标。并且location对象包含两个值。

1. location ['x']-返回元素的'x'坐标
2. location ['y']-返回元素的“ y”坐标

尺寸

就像位置一样，每个WebElement都具有宽度和高度。可用作尺寸对象。

1. size ['width']-返回元素的“ width”
2. size ['height']-返回元素的“高度”

使用（x，y）坐标和宽度，高度值，我们可以裁剪图像并将其存储在文件中。

from selenium import webdriver
from PIL import Image

driver = webdriver.Firefox(executable_path='[Browser Driver Path]')
driver.get('https://www.google.co.in')

element = driver.find_element_by_xpath("//div[@id='hplogo']")

location = element.location
size = element.size

driver.save_screenshot("/data/image.png")

x = location['x']
y = location['y']
width = location['x']+size['width']
height = location['y']+size['height']

im = Image.open('/data/WorkArea/image.png')
im = im.crop((int(x), int(y), int(width), int(height)))
im.save('/data/image.png')

您可以使用python网络驱动程序从Windows捕获图像。使用以下页面需要捕获屏幕截图的代码

driver.save_screenshot('c:\foldername\filename.extension(png,jpeg)')

爪哇

public  void captureScreenShot(String obj) throws IOException {
    File screenshotFile=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    FileUtils.copyFile(screenshotFile,new File("Screenshots\\"+obj+""+GetTimeStampValue()+".png"));
}

public  String GetTimeStampValue()throws IOException{
    Calendar cal = Calendar.getInstance();       
    Date time=cal.getTime();
    String timestamp=time.toString();
    System.out.println(timestamp);
    String systime=timestamp.replace(":", "-");
    System.out.println(systime);
    return systime;
}

使用这两种方法，您还可以对日期和时间进行截屏。

使用RemoteWebDriver，在使用截图功能扩展Node之后，我将这样存储截图：

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

您可以在任何需要的地方使用此方法。然后，我假设您可以在surefire-reports / html / custom.css上自定义maven-surefire-report-plugin的样式表，以便您的报告包含指向每个测试的正确屏幕截图的链接？

爪哇

String yourfilepath = "E:\\username\\Selenium_Workspace\\foldername";

// take a snapshort
File snapshort_file = ((TakesScreenshot) mWebDriver)
        .getScreenshotAs(OutputType.FILE);
// copy the file into folder

FileUtils.copyFile(snapshort_file, new File(yourfilepath));

希望这能解决您的问题

C＃

    // Take a screenshot and save it to filename
    Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
    screenshot.SaveAsFile(filename, ImageFormat.Png);
}

    {
        var cantakescreenshot = (driver as ITakesScreenshot) != null;
        if (!cantakescreenshot)
            return;
        var filename = string.Empty + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + DateTime.Now.Millisecond;
        filename = path + @"\" + filename + ".png";
        var ss = ((ITakesScreenshot)driver).GetScreenshot();
        var screenshot = ss.AsBase64EncodedString;
        byte[] screenshotAsByteArray = ss.AsByteArray;
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path);
