Best way to take screenshots of tests in Selenium 2?

Question

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

Answer 1

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

Answer 2

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

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

Answer 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.

Answer 5

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"));

Answer 6

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.
