Pagetience

Build Status

Pronounced like "patience".

Using a simple DSL, you can declare which of your page object elements must be present and visible on the page before your code can consider it loaded.

Installation

Add this line to your application's Gemfile:

gem 'pagetience'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install pagetience

Usage

To use Pagetience, simply include Pagetience in your page object class and then use the required method to set which elements must be visible on the page for it to be considered loaded.

class GooglePage
  include PageObject
  include Pagetience

  text_field :search, name: 'q'
  required :search
end

When an instance of your page object is created then the required elements will be checked for.

Page transitions

Using the wait_for_transition_to method within your page object, you can now wait for an expected page to transition to.

class FirstPage
  include PageObject
  include Pagetience

  text_field :a, id: 'a'
  button :b, id: 'b'
  required :a, :b

  def go_to_b
    self.a = 'a'
    self.b

    wait_for_transition_to SecondPage
  end
end

class SecondPage
  include PageObject
  include Pagetience

  button :c, id: 'c'
  required :c

  def back_to_a
    self.c

    wait_for_transition_to FirstPage, 15, 5 # wait up to 15 seconds, polling every 5 seconds
  end
end

# In a test

@current_page = FirstPage.new(@browser).go_to_b
expect(@current_page.loaded?).to eq true # true
expect(@current_page).to be_an_instance_of SecondPage # true

Waiting for individual elements

The wait_for_element method allows you to wait for a specific element on the page to be there. It doesn't have to be one of your required fields -- it just has to declared.

class SomePage
  include PageObject
  include Pagetience

  button :foo, id: 'foo'

  def wait_for_foo
    wait_for_element :foo
  end

  def wait_longer_for_foo
    wait_for_element :foo, 60, 5 # wait up to 60 seconds, polling every 5 seconds
  end
end

Configuration

Pagetience can be configured, too.

Pagetience.configure do |config|
  config.timeout = 60
  config.polling = 5
end

It can then be retrieve easily!

def give_me_a_property
  Pagetience.config.timeout
end

give_me_a_property # => 60

Adjusting the Timeout/Polling for a specific Page

You can use the waiting method to specify how long you want to wait and, optionally, at what interval to poll the page for element visibility.

The default timeout is 30 seconds, polling every second.

class GooglePage
  include PageObject
  include Pagetience

  text_field :search, name: 'q'
  required :search
  waiting 60, 5 # wait up to 60 seconds, polling every 5 seconds
end

Supported Platforms

Currently, this gem only works with the page-object gem. It's a high priority to make working with other page object/webdriver libraries easier.

Notes/Todo/Issues

  1. Add platform support for Selenium WebDriver
  2. Add platform support for Watir WebDriver
  3. SitePrism?
  4. Documentation
  5. Organize unit tests
