Best Way to Take Screenshots of Tests in Selenium 2

Best way to take screenshots of tests in Selenium 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

How can I take a screenshot with Selenium WebDriver?

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"));

How to capture a screenshot after each step in tests with JAVA and Cucumber?

Solved this using Aspects. Was pretty tricky, note the annotation:

@After("call(public * cucumber.runtime.StepDefinitionMatch.runStep(..)) && within(cucumber.runtime.Runtime)")
