Eiffel Selenium binding

Overview

Selenium will help you test your web applications effectively and efficiently against a vast number of browsers and platforms. This client is a binding for the REST API interface defined in the WebDriver protocol http://code.google.com/p/selenium/wiki/JsonWireProtocol.

WARNING this API is still under development, and maybe it will change

Requirements

• Get the server selenium-server-standalone-#.jar file provided here: http://code.google.com/p/selenium/downloads/list

• Download and run that file, replacing # with the current server version.

  java -jar selenium-server-standalone-#.jar
  (it only has a Firefox WebDriver by default)
  
  But you can add other drivers doing something like that (change PATH_TO to the corresponding value in your environment)
  java -jar selenium-server-standalone-2.32.0.jar  
  -Dwebdriver.chrome.driver=%PATH_TO%\chromedriver.exe  -Dwebdriver.ie.driver=%PATH_TO%\IEDriverServer.exe 
  

Getting Started Selenium-WebDriver API

(Eiffel binding only support (for now) RemoteWebDriver) The examples and guide are based on http://docs.seleniumhq.org/docs/03_webdriver.jsp#introducing-the-selenium-webdriver-api-by-example

WebDriver is a tool for automating web application testing, and in particular to verify that they work as expected.

class
	EXAMPLE_SEARCH

feature -- Example
	search
		local
			web_driver : WEB_DRIVER
			wait : WEB_DRIVER_WAIT
		do
			--Create a new instance of a Web driver
       		create web_driver.make

       		-- Start session with chrome
       		web_driver.start_session_chrome

       		-- Go to Google
       		web_driver.to_url ("http://www.google.com/")

       		-- Find the text input element by its name
    	     if attached web_driver.find_element ((create{SE_BY}).name ("q")) as l_element then

  				-- Enter something to search for
   	    		l_element.send_keys(<<"Eiffel Room">>)

     	  		-- Now submit the form. WebDriver will find the form for us from the element
     			l_element.submit

		     end
			 if attached web_driver.get_page_tile as l_title then
		     	print ("%NPage title is:" + l_title)
		     end
			
			-- Google's search is rendered dynamically with JavaScript.
    	    -- Wait for the page to load, timeout after 10 seconds
			 create wait.make (web_driver,10)
			 wait.until_when ("Eiffel Room")


			  if attached web_driver.get_page_tile as l_title then
		     	print ("%NPage title is:" + l_title)
		     end

			-- close the window
			web_driver.window_close
		end
end

Selenium-WebDriver API Commands and Operations

To learn more go to [Selenium documentation] (http://docs.seleniumhq.org/docs/03_webdriver.jsp#introducing-the-selenium-webdriver-api-by-example)

Fetching a Page

The first thing you are likely to want to do with WebDriver is navigate to a page. 

	web_driver.to_url ("http://www.google.com/")

Locating UI Elements (WebElements)

By ID

Example of how to find an element that looks like this:

<div id="head">...</div>

Eiffel Code

web_driver.find_element ((create{SE_BY}).id ("head"))

By Name

Example of how to find an element that looks like this:

<input name="cheese" type="text"/>

Eiffel Code

web_driver.find_element ((create{SE_BY}).name ("cheese"))

By Class Name

Example of how to find an element that looks like this:

<div class="cheese"><span>Cheddar</span></div><div class="cheese"><span>Gouda</span></div>

Eiffel Code

web_driver.find_element ((create{SE_BY}).class_name ("cheese"))

By CSS Selector

Example of how to find an element that looks like this:

<div id="food"><span class="dairy">milk</span><span class="dairy aged">cheese</span></div>

Eiffel Code

web_driver.find_element ((create{SE_BY}).css_selector ("#food span.dairy.aged"))

By Link Text

Example of how to find an element that looks like this:

<a href="http://www.google.com/search?q=EWF">EWF</a>>

Eiffel Code

web_driver.find_element ((create{SE_BY}).link_text ("EWF"))

By Partial Link Text

Example of how to find an element that looks like this:

<a href="http://www.google.com/search?q=ewf">search for ewf</a>>

Eiffel Code

web_driver.find_element ((create{SE_BY}).partial_link_text ("ewf"))

By Tag Name

Example of how to find an element that looks like this:

<iframe src="..."></iframe>

Eiffel Code

web_driver.find_element ((create{SE_BY}).tag_name ("iframe"))

By XPath

Example of how to find an element that looks like this:

<input type="text" name="example" />

Eiffel Code

web_driver.find_element ((create{SE_BY}).xpath ("//input"))
