Moving Default Data: undefined method 'merge' for nil:NilClass

[Michael Stamps]

Making my way through the book, I get to the 'Moving our default data' section and got an error.  After banging on it for a while, I decided I got something wrong somewhere that I was not able to find, so I started over completely.  Then it happened again.

I created the config/data folder, the new default.yml file with the listed values.  I ran the "Adopting a puppy using all default data" scenario and am met with an error:

NoMethodError: undefined method `merge' for nil:NilClass

./features/support/pages/checkout_page.rb:19:in `checkout'

./features/step_definitions/adopting_puppies_steps.rb:50:in `/^I complete the adoption$/'

C:\Ruby\workspace\test_puppies\features\adopting_puppies.feature:89:in `And I complete the adoption'

checkout_page.rb lines 18-21:

  def checkout(data ={})

    populate_page_with data_for(:checkout_page, data)

    place_order

  end

adopting_puppies_steps.rb 49-51:

When(/^I complete the adoption$/) do

  on(CheckoutPage).checkout

end

  Scenario: Adopting a puppy using all default data

    When I click the View Details button for "Brook"

    And I click the Adopt Me button

    And I click the Complete the Adoption button

    And I complete the adoption

    Then I should see "Thank you for adopting a puppy!"

default.yml contents:

checkout_page:

name: Cheezy

address: 123 Main Street

email: che...@example.com

pay_type: Check

Today I learned to indent my yml contents properly.

Thanks!

HI Michael,

After posting my query, I realised that you had gone through the same issue with the error - NoMethodError: undefined method `merge' for nil:NilClass

Can you please help me sorting it out.

Thanks,

Sanjay
