Hi,

I am a total beginner of Ruby and Selenium and i want to use both =)

1. Selenium-webdriver gem - How do I find out which methods that this  
gem contains or other gems?  
2. Catch a bug – If a link or element is missing on the page how do I  
catch this defect and output it and then continue with my test script?  
Some design tips?

Best Regards,  
Mattias

I recommend using Watir-Webdriver, as this is Selenium with a great  
interface.

Check out tips and examples here:  
[http://watirwebdriver.com/](http://watirwebdriver.com/)

Plenty of methods are shown there and in the documentation. As for  
catching missing elements, you have methods such as "present?" returning  
a boolean value.

Try this:

require 'watir-webdriver'  
b = Watir::Browser.start '[bit.ly/watir-webdriver-demo](http://bit.ly/watir-webdriver-demo)'  
l = b.link :text =\> 'Google Docs'  
b.goto l.href

Hi again,

What actually happens below? See my comments after #  
Would really appreciate if someone wanted to take the time to explain.

require 'rubygems' #lib?  
require 'selenium-webdriver' #lib?

driver = Selenium::WebDriver.for :firefox #instantiate driver with  
Selenium and Webdriver methods?  
driver.get "[http://google.com](http://google.com)"

element = driver.find\_element :name =\> "q" # What happens here? :name =\>  
"q"?  
element.send\_keys "Cheese!"  
element.submit

puts "Page title is #{driver.title}"

wait = Selenium::WebDriver::Wait.new(:timeout =\> 2)#Wait is a new class?  
wait.until { driver.title.downcase.start\_with? "cheese!" }#Verify that  
cheese has been printed?

puts "Page title is #{driver.title}"  
driver.quit

Best Regards  
Mattias

You don't need this in Ruby 1.9

> require 'selenium-webdriver' #lib?

Have a look at this:  
[http://watirmelon.com/2011/05/05/selenium-webdriver-vs-watir-webdriver-in-ruby/](http://watirmelon.com/2011/05/05/selenium-webdriver-vs-watir-webdriver-in-ruby/)

This just creates an instance of firefox with a temp profile which can  
be controlled via Selenium-webdriver

> driver.get "[http://google.com](http://google.com)"
> 
> element = driver.find\_element :name =\> "q" # What happens here? :name =\>  
> "q"?

The element on the page with the name "q" happens to be the search text  
field. I recommend using Firebug to find out what each element can be  
identified by.

Watir-webdriver's latest version has waiting built-in, it looks like  
Selenium has a seperate wait module.

> wait.until { driver.title.downcase.start\_with? "cheese!" }#Verify that  
> cheese has been printed?

You're passing a block to the wait module, until method which will stop  
waiting once it evaluates to "true". This waits until the page has  
loaded to a point that it has changed the title of the browser window.

> puts "Page title is #{driver.title}"  
> driver.quit

I'm not sure about Selenium, but with watir-webdriver using "close"  
rather than "quit" cleans up the temp files as well.

> Best Regards

This is what the same sequence looks like with watir-webdriver:

require 'watir-webdriver'  
driver = Watir::Browser.new :firefox  
driver.goto "[http://google.com](http://google.com)"  
element = driver.text\_field(:name =\> "q")  
element.set "Cheese!\n"  
puts "Page title is #{driver.title}"  
driver.wait\_until { driver.title.downcase.start\_with? "cheese!" }  
puts "Page title is #{driver.title}"  
driver.close
