Take a screenshot with Selenium WebDriver

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

Answer: Take a screenshot with Selenium WebDriver

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

WebDriver driver = new FirefoxDriver(); driver.get("http://www.google.com/"); File scrFile =…

My first time using Selenium was last year. I installed Selenium IDE, Firefox plugin, it's basically a recording tool and there is no "real" scripting involved. Though once you have recorded a test or test suite you can edit the back end code that is generated. I am on a serious journey to become an EXPERT at QA Test Automation so last night I installed Selenium-Webdriver on my machine. Today I took some time to read about it on the train and this evening I became Dr. Evil!!!!!

Some Background:

Selenium automates browsers and web applications. It has a variety of Tools Selenium-Webdriver, Selenium RC and Selenium IDE. However, for the purpose of this exercise we are going to learn Selenium-Webdriver. Selenium-Webdriver seems to be the most interesting. You can run scripts in the following languages: Ruby, Java, Perl, C#, Python, and PHP. For the purpose of the exercise we are using Ruby.

Assumptions for this exercise:

You have Ubuntu Linux installed and have a basic understanding of it

You have Ruby installed and have a basic understanding of it

You have Firefox Installed and have a basic understanding of it

Install:

Go to your Ubuntu Terminal and type:

$sudo gem install selenium-webdriver

selenium-webdriver should be successfully installed with rubygems

Let's start scripting:

From your Ubuntu Linux Terminal command line prompt:

type:

irb - this will launch interactive ruby

press enter

next type:

require 'rubygems' - this loads rubygems

press enter

next type:

require 'selenium-webdriver' - this loads the webdriver for use

press enter

next type:

driver = Selenium::WebDriver.for :firefox - this helps load firefox you will see JSON message. After the JSON message is received a blank firefox window will open up

finally type:

driver.get "http://hisandhernews.com" - This will open up hisandhernews.com website

press enter

NOTE: Each time you enter you will see "true" which means that Ruby has evaluated the Object you have entered.

Sample:

aq-kiss@aq-kiss-Dell-DXP061:~$ irb irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'selenium-webdriver' => true irb(main):003:0> driver = Selenium::WebDriver.for :firefox Warning: multi_json is using default ok_json engine. Suggested action: require and load an appropriate JSON library. => #<Selenium::WebDriver::Driver:0x..fb7221548 browser=:firefox> irb(main):004:0> driver.get "http://hisandhernews.com" => "" irb(main):005:0>

HOLY COW You just Learned how to Script in Selenium with Ruby in a Ubuntu Linux Environment!!!!!

Yes! I know selenium API lets you switch between windows:

driver.switch_to_window('window_name')

But what if I wanted to switch between windows and I don't know the window name?

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Function name: switch_window

args: none

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

#Definition of switching windows from popup to parent window # def switch_window()       current_windows = page.driver.browser.window_handles     if current_windows.length == 1 and @parent       browser.switch_to.window @parent       @parent = nil       return     end         current_window = page.driver.browser.window_handle         current_windows.each do |win_handle|       if win_handle == current_window         if current_windows.length > 1           @parent = win_handle           @browser_parent = page.driver.browser           next         end       end             page.driver.browser.switch_to.window win_handle             break         end

  end

Because Cucumber relies solely on an implementation of Selenium-webdriver any limitation with selenium-webdriver is carried over, I was automating an hack of a tool at an old work place which required right-click event to access some fancy AJAX menu my thoughts! bleeeeh! but a new challenge is always good regardless of how stupid it is. being a strong believer in selenium-webdriver, my thoughts where "selenium is y silver bullet and I bet selenium handles right click in a single line of code"  Optimism is the mother all evil!! after reading going through selenium API docs for the uptinth time , I gave up search for a right click function and wrote a javascript function which execute nicely in selenium, BAMMM!! problem solve.

see below for how to perform a right click event on an AJAX page :

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Function name: RightClickOnElement

args: elementid

         ID of element to perform right click on

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

def RightClickOnElement(elementid) page.execute_script(' function contextMenuClick(element){     var evt = element.ownerDocument.createEvent("MouseEvents");     var RIGHT_CLICK_BUTTON_CODE = 2; // the same for FF and IE     evt.initMouseEvent("contextmenu", true, true,          element.ownerDocument.defaultView, 1, 0, 0, 0, 0, false,          false, false, false, RIGHT_CLICK_BUTTON_CODE, null);     if (document.createEventObject){         // dispatch for IE        return element.fireEvent("onclick", evt)      }     else{        // dispatch for firefox + others       return !element.dispatchEvent(evt);     } } item = document.getElementById('+elementid+'); contextMenuClick(item ); ') end
