Selenium and Watir, as we know, are the two most popular open-source testing frameworks. The next big thing is WebDriver, which is now merged with Selenium 2. Thanks Jari Bakken (who is also the creator of Celerity), we have Ruby bindings for Selenium 2 and even Watir wrapper of it: watir-webdriver, which some might refer it as Watir 2.0. With watir-webdriver, users can pretty much reuse existing Watir scripts, with minor changes.

What are the benefits of using watir-webdriver comparing existing Watir 1.6.5?

• Run same test scripts in IE, Firefox, Google Chrome and HTMLUnit (headless)
• No JSSH plugin required for running tests in Firefox
• Synergy of combination of Selenium and Watir

In last appearance at Watir Podcast, I said future TestWise versions will support WebDriver. Now you can try web-driver in IDE!

1. Download TestWise-2.0b1-setup.exe and install
2. In TestWise, open sample project c:\program files\testwise\samples\demo\demo.tpr (if you are using TestWise first, it shall be pre-loaded)
3. Select the first test script file (left mouse click the file name on the left): ajax_rwebspec_spec.rb,
   choose your browser (IE, Firefox or Chrome), then run it
    

Please note that both Selenium 2 and TestWise2 are at early development stage, so please use Watir 1.6.5 and TestWise 1.9 for production use.

For some sites (especially in .NET world), users are presented a native windows' authentication window (like below) before can access to it.

The standard open_browser in Watir won't work (get stuck), as it will be waiting response from the browser.

  open_browser("http://secure.site.com") # will stuck 

To add a bit more complexity, we expect the same tests to pass whether user has already logged in or not.

The solution is:

• Detecting Login Window using Ruby's timeout
• Use AutoIt to fill user name and password in native Windows Login Window.

    begin
      Timeout::timeout(5) {
        open_browser("http://secure.site.com")
      }
    rescue Timeout::Error => e
      # debug "Timeout error on get to site, maybe asking for login"
      autoit = WIN32OLE.new('AutoItX3.Control')
      win_title = "Connect to edam.bluefirems.com.au"
      ret = autoit.WinWait(win_title, '', 10)
      if ret
        autoit.ControlSetText(win_title, "", "Edit2", username)
        autoit.ControlSetText(win_title, "", "Edit3", password)
        autoit.ControlClick(win_title, "", "Button3")
      end
   end

The above test scripts will work, but not readable. By applying 'Extract Function' and "Move to Helper" Refactorings in TestWise, we get:

    # ...
    rescue Timeout::Error => e
      # debug "Timeout error on get to site, maybe asking for login"
      # calling helper function in test_helper.rb
       
      login_as("zhimin@secure.site.com", "Secret")    
    end
