A simple gem that assists in creating flexible page objects for testing browser based applications. The goal is to facilitate creating abstraction layers in your tests to decouple the tests from the item they are testing and to provide a simple interface to the elements on a page. It works with both watir-webdriver and selenium-webdriver.
The project wiki is the first place to go to learn about how to use page-object.
The rdocs for this project can be found at rubydoc.info.
To see the changes from release to release please look at the ChangeLog
To read about the motivation for this gem please read this blog entry
There is a book that describes in detail how to use this gem and others to create a complete view of testing web and other types of applications. The book is named Cucumber & Cheese

Defining your page object
You define a new page object by including the PageObject module:
class LoginPage include PageObject end
When you include this module numerous methods are added to your class that allow you to easily define your page. For the login page you might add the following:
class LoginPage include PageObject text_field(:username, :id => 'username') text_field(:password, :id => 'password') button(:login, :id => 'login') end
Calling the text_field and button methods adds several methods to our page object that allow us to interact with the items on the page. To login using this page we could simply write the following code:
login_page.username = 'cheezy' login_page.password = 'secret' login_page.login
Another approach might be to create higher level methods on our page object that hide the implementation details even further. Our page object might look like this:
class LoginPage include PageObject text_field(:username, :id => 'username') text_field(:password, :id => 'password') button(:login, :id => 'login') def login_with(username, password) self.username = username self.password = password login end end
and your usage of the page would become:
login_page.login_with 'cheezy', 'secret'
Creating your page object
page-object supports both watir-webdriver and selenium-webdriver. The one used will be determined by which driver you pass into the constructor of your page object. The page object can be create like this:
browser = Watir::Browser.new :firefox my_page_object = MyPageObject.new(browser)
browser = Selenium::WebDriver.for :firefox my_page_object = MyPageObject.new(browser)
- Fork the project.
- Test drive your feature addition or bug fix. Adding specs is important and I will not accept a pull request that does not have tests.
- Make sure you describe your new feature with a cucumber scenario.
- Make sure you provide RDoc comments for any new public method you add. Remember, others will be using this gem.
- Commit, do not mess with Rakefile, version, or ChangeLog. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
