问题

Does anyone know if it\'s possible to take a screenshot using Selenium WebDriver? (Note: Not Selenium RC)

回答1:

Java

Yes, it is possible. The following example is in Java:

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"));

回答2:

Python

Each WebDriver has a .save_screenshot(filename) method. So for Firefox, it can be used like this:

from selenium import webdriver

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

Confusingly, a .get_screenshot_as_file(filename) method also exists that does the same thing.

There are also methods for: .get_screenshot_as_base64() (for embedding in html) and .get_screenshot_as_png()(for retrieving binary data).

and Note that WebElements have a .screenshot() method that works similarly, but only captures the selected element.

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);
   });
});

Ruby

require 'rubygems'
require 'selenium-webdriver'

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

more file types and options are available and you can see them in takes_screenshot.rb

I got this issue resolved. You can augment the RemoteWebDriver to give it all of the interfaces its proxied driver implements:

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

        $filedata = $this->currentScreenshot();
        file_put_contents($filepath, $filedata);
    }

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

Java (Robot Framework)

I used this method for taking screen shot.

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();
    }
}

You may use this method wherever required.

Java

Seems to be missing here - taking screenshot of a specific element in Java:

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);
}

回答13:

I could not get the accepted answer to work, but as per the current WebDriver documentation, the following worked fine for me with Java 7 on OS X 10.9:

   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);
   }

Python - Screenshot of Element:

This is a pretty old question and has multiple answers. However it seems taking screenshot of a particular web element using Python is missing here.

location

A web element has its own position on page and generally it is measured in x and y pixels and known as (x,y) co-ordinates of element. And location object contains two values.

location[‘x’] - returns ‘x’ co-ordinate of the element
location[‘y’] - returns ‘y’ co-ordinate of the element

size

Like location, each WebElement has width and height; Available as size object.

size[‘width’] - returns ‘width’ of the element
size[‘height’] - returns ‘height’ of the element

Using (x,y) co-ordinates and width, height values we can crop the image and store it in a file.

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')

回答20:

Python

You can capture the image from windows using python web driver. Use the code below which page need to capture the screenshot

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

回答21:

Java

Using RemoteWebDriver, after augmenting the Node with screenshot capability, I would store the screenshot like so:

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();
    }
}

You may use this method wherever required. Then, I assume you can customize the style sheet of maven-surefire-report-plugin at surefire-reports/html/custom.css so that your reports include the link to the correct screenshot for each test?

回答22:

C#

public static void TakeScreenshot(IWebDriver driver, String filename)
{
    // Take a screenshot and save it to filename
    Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
    screenshot.SaveAsFile(filename, ImageFormat.Png);
}

回答23:

You can use the following code snippet/function to take screenshot with the selenium:

    public void TakeScreenshot(IWebDriver driver, string path = @"output")
    {
        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);
        ss.SaveAsFile(filename, ImageFormat.Png);
    }

You can give a try to AShot API. Here's the github link for the same.

回答25:

Java

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;
}

Using these two methods you can take a screen shot with the date and time as well.
