Module: Watirsome::Initializers

Defined in:
lib/watirsome/initializers.rb

Overview

Initializes page class. Allows to define “#initialize_page” which will be called as page constructor. After page is initialized, iterates through region and initialize each of them.

Examples:

Page Initializer

class Page
  include Watirsome

  attr_accessor :page_loaded

  def initialize_page
    self.page_loaded = true
  end
end

page = Page.new(@browser)
page.page_loaded
#=> true

Region Initializer

module HeaderRegion
  def initialize_region
    self.page_loaded = true
  end
end

class Page
  include Watirsome
  include HeaderRegion

  attr_accessor :page_loaded
end

page = Page.new(@browser)
page.page_loaded
#=> true

def initialize(browser)
  @browser = browser
  initialize_page if respond_to?(:initialize_page)
  initialize_regions
end

#initialize_regions ⇒ Object

Iterates through definitions of “#initialize_region”, thus implementing polymorphic Ruby modules (i.e. page regions).
