Geocoder: Stub out address geocoding during RSpec unit tests

mock_geocoder.rb

# In spec_helper:
# RSpec.configure do |config|
#   ...
#   config.include(MockGeocoder)
# end
#
# In your tests:
# it 'mock geocoding' do
#   mock_geocoding! # You may pass additional params to override defaults (i.e. :coordinates => [10, 20])
#   address = Factory(:address)
#   address.lat.should eq(1)
#   address.lng.should eq(2)
# end

require 'geocoder/results/base'

module MockGeocoder
  def self.included(base)
    base.before :each do
      ::Geocoder.stub(:search).and_raise(RuntimeError.new 'Use "mock_geocoding!" method in your tests.')
    end
  end

  def mock_geocoding!(options = {})
    options.reverse_merge!(:address => 'Address', :coordinates => [1, 2], :state => 'State', :state_code => 'State Code', :country => 'Country', :country_code => 'Country code')

    MockResult.new.tap do |result|
      result.stub options
      Geocoder.stub :search => [result]
    end
  end

  class MockResult < ::Geocoder::Result::Base
    def initialize(data = [])
      super(data)
    end
  end
end

Hi. I'm having a problem using this because the Geocoder::Result module isn't found.

spec/support/mock_geocoder.rb:37:in `<module:MockGeocoder>': uninitialized constant Geocoder::Result (NameError)

As far as I can tell, it's never loaded by Geocoder.

Do I need to require this file specifically? How do I do that?

@dtuite Did you ever figure it out?

@jmccartie I'm afraid not. Let me know if you get anywhere please.

@dtuite I bailed on trying to stub out the object and used FakeWeb instead.

@jmccartie Try this if you like: http://dtuite.github.com/how-to-test-the-geocoder-gem.html

add require 'geocoder/results/base' at the top of gist

For anyone using Rspec 2+, I made a fork that works with the new expect syntax.
