How to call a page-object from a class.rb at Support folder

I am using the page-object gem. Suppose i have a page-object on features/bussines/pages/booking_page.rb for a page like:

class Booking

   include PageObject

   span(:txtFirstName,   :id => 'details_first_name')

end

...and i use a "tools" class located at features/support/tools.rb with something like:

class MyTools

  def call_to_page_object
    on Booking do |page|
       puts page.txtFirstName
    end
  end
end

...but this approach fails because calling to the object from the class is not allowed:

undefined method `on' for #<Booking:0x108f5b0c8> (NoMethodError)

Pretty sure i'm missing some concept on the way to use the page-object from a class but don't realize whats the problem. Can you please give me an idea about what could be wrong here, please?

Thank you very much!

============================

Justin found the reason why the call to the class crash. The final class code results:

class MyTools

  #Include this module so that the class has the 'on' method
  include PageObject::PageFactory

  def initialize(browser)
    #Assign a browser object to @browser, which the 'on' method assumes to exist
    @browser = browser
  end

  def getCurrentRewards
    on Booking do |page|
      rewards_text = page.rewards_amount
      rewards_amount = rewards_text.match(/(\d+.*\d*)/)[1].to_f
      puts "The current rewards amount are: #{rewards_amount}."
      return rewards_amount
    end
  end

end

And the call to the function:

user_rewards = UserData.new(@browser).getCurrentRewards

Why it did not work me? Two main reasons:

Thanks all!

To use the on (or on_page) method requires two things:

  1. The method to be available, which is done by including the PageObject::PageFactory module.
  2. Having a @browser variable (within the scope of the class) that is the browser.

So you could make your MyTools class work by doing:

class MyTools
  #Include this module so that the class has the 'on' method
  include PageObject::PageFactory

  def initialize(browser)
    #Assign a browser object to @browser, which the 'on' method assumes to exist
    @browser = browser
  end

  def call_to_page_object
    on Booking do |page|
       puts page.txtFirstName
    end
  end
end

You would then be calling your MyTools class like:

#Assuming your Cucumber steps have the the browser stored in @browser:
MyTools.new(@browser).call_to_page_object

Your class should use the extend keyword to access special class methods like span:

class Booking
   extend PageObject
   span(:txtFirstName, :id => 'details_first_name')
end

I hope this works.

What are you trying to do?

Did you read Cucumber & Cheese book?

Pages should be in the features/support/pages folder. You can put other files that pages need there too.

If you want to use on method in a class, you have to add this to the class:

include PageObject

The code from MyTools class looks to me like it should be in Cucumber step file, not in a class.
