Best way to take screenshots of tests in Selenium 2?

I need a way to take screenshots of my functional tests. Right now I'm using Selenium 2 with C# bindings. I pretty much want to take a screenshot at the end of the test to make sure the desired page is displayed. Are there any particular tools you guys know of that I can incorporate into my C# code that will trigger a screenshot? I couldn't find a built-in Se开发者_如何学编程lenium 2 solution (without looking it over).

To do screenshots in Selenium 2 you need to do the following

driver = new FireFoxDriver(); // Should work in other Browser Drivers
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk");
Screenshot ss = ((ITakesScreenshot) driver).GetScreenshot();

//Use it as you want now
string screenshot = ss.AsBase64EncodedString;
byte[] screenshotAsByteArray = ss.AsByteArray;
ss.SaveAsFile("filename", ImageFormat.Png); //use any of the built in image formating
ss.ToString();//same as string screenshot = ss.AsBase64EncodedString;

That code should work, as I quickly tested it in IronPython Repl. See the IronPython code below

import clr
clr.AddReference("WebDriver.Common.dll")
clr.AddReference("WebDriver.Firefox.dll")
from OpenQA.Selenium import *
from OpenQA.Selenium.Firefox import *
driver = FirefoxDriver()
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk")
s = driver.GetScreenshot()
s.AsBaseEncodedString
# HUGE string appears in the REPL

var driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("http://www.google.com");
var ss = driver.GetScreenshot();   
ss.SaveAsFile("ss.png", System.Drawing.Imaging.ImageFormat.Png);

I don't know if it matters, but I ended up having to cast the driver when i was writing in c#.

something like:

Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();

Just use the extension method TakeScreenshot() in one line of code.

IWebDriver driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("Your_Homepage_Url");

driver.TakeScreenshot().SaveAsFile("file_name_string", ImageFormat.Jpeg);

1. Add a reference of System.Drawing in your solution/project.
2. Use System.Drawing.Imaging namespace in your test.

Here I am capturing the screen shot of Facebook Home page.

using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
using NUnit.Framework;
using System.IO;
using System.Collections;
using System.Drawing.Imaging;

namespace FacebookRegistrationUsingC_Sharp
{
    [TestFixture]
    public class ScreenShot
    {
        IWebDriver driver = null;
        IWebElement element = null;

        [SetUp]
        public void SetUp()
        {
            driver = new ChromeDriver("G:\\Selenium_Csharp\\Jar\\chromedriver_win32");           
            driver.Navigate().GoToUrl("https://www.Facebook.com");
            driver.Manage().Window.Maximize();

        }
        [Test]
        public void TestScreenShot()
        {           

            Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
            ss.SaveAsFile("e:\\pande", System.Drawing.Imaging.ImageFormat.Jpeg);
        }

        [TearDown]
        public void TearDown()
        {
            driver = null;
            element = null;
        }
    }
}

public void TakeScreenshot(string saveLocation) {
        var location = GetPath() + _name + "\\" + saveLocation + ".png";
        var ssdriver = _driver as ITakesScreenshot;
        var screenshot = ssdriver.GetScreenshot();
        screenshot.SaveAsFile(location, ImageFormat.Png);
    }

This code will help you to take screen shot

JAVA

protected void fullPageScreenshot(String testname) {
            String timeStamp = new SimpleDateFormat("dd_MM_yyyy_HH_mm_ss").format(Calendar.getInstance().getTime());
            String imageName = testname + "-" + timeStamp + ".png";
            Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(2000))
                    .takeScreenshot(DriverManager.getDriver());
            try {
                ImageIO.write(screenshot.getImage(), "PNG", new File("./FullPage_Screenshots/" + imageName));
            } catch (Exception e) {
                System.out.println("Capturing FullPage Screenshot failed");
            }
        }

use Ashot library to take fullpage screenshots - even where pages needs to be scrolled https://mvnrepository.com/artifact/ru.yandex.qatools.ashot/ashot/1.5.4

Use System.Drawing.Imaging reference. Following code can be used for taking screenshot.

IWebDriver driver = new FirefoxDriver();
ITakesScreenshot screenshotDriver = driver as ITakesScreenshot;
Screenshot screenshot = screenshotDriver.GetScreenshot();
String fp = "D:\\" + "snapshot" + "_"+ DateTime.Now.ToString("dd_MMMM_hh_mm_ss_tt") + ".png";
screenshot.SaveAsFile(fp, ImageFormat.Png);

Notes: Timestamp has two advantages: 1) You'll get to know the perfect DateTime when screenshot is taken. 2) SaveAsFile function overwrites the existing file. So, DateTime can help for different file creation.

        ScreenCaptureJob scj;
        scj = new ScreenCaptureJob();
        // Specify the path & file name in which you want to save         
        scj.OutputScreenCaptureFileName = @"C:\Users\jpavankumar\Desktop\Screencaptuere\ScreenRecording4.wmv";
        // Start the Screen Capture Job
        scj.Start(); scj.Stop();

Try this code out here ... hope it will be useful to you .... !

Define this in global code :

var counter = DateTime.Now.Ticks.ToString();

((ITakesScreenshot)driver).GetScreenshot().SaveAsFile((snap +counter + ".jpg").ToString(), OpenQA.Selenium.ScreenshotImageFormat.Jpeg);
test.Log(LogStatus.Fail, "Snapshot below: " + test.AddScreenCapture(snap + counter + ".jpg"));

driver.Url = "https://www.amazon.in/";
//Store image in bin folder
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile("CurrentPage.png"); 
//Store image in D drive        
((ITakesScreenshot)driver).GetScreenshot().SaveAsFile(@"D:\CurrentPage.png");

Best way to take screenshot and store in the file location in a generic way in python :

def screenShots(self):
        fileName= NewFile + "." + str(round(time.time() * 1000)) + ".png"
        screenshotDirectory = "../screenshot/"  #Move to that directory where you want ot store the screenshot
        relativeFileName = screenshotDirectory + fileName
        currentDirectory = os.path.dirname(__file__)
        destinationFile = os.path.join(currentDirectory,relativeFileName)
        destinationDirectory = os.path.join(currentDirectory,screenshotDirectory)

        try:
            if not os.path.exists(destinationDirectory):
                os.makedirs(destinationDirectory)
            self.driver.save_screenshot(destinationFile)

            self.log.info("Screenshot saved to directory" + destinationFile)

        except:
            self.log.error("Exception Occured")
            print_stack()

Using selenium there were two calls I was familiar with: captureEntirePageScreenshot and captureScreenshot. You might want to look into those calls to see if they'll accomplish what you're after.
