Rails Geocoder Testing with rspec - ruby-on-rails

Question

I am trying to set up my RSpec tests to use stubs rather then using networking to do the geocoding.
I added this:
before(:each) do
Geocoder.configure(:lookup => :test)
Geocoder::Lookup::Test.add_stub(
"Los Angeles, CA", [{
:latitude => 34.052363,
:longitude => -118.256551,
:address => 'Los Angeles, CA, USA',
:state => 'California',
:state_code => 'CA',
:country => 'United States',
:country_code => 'US'
}],
)
end
I am using FactoryGirl to create the test data like so:
FactoryGirl.define do
factory :market do
city 'Los Angeles'
state 'CA'
radius 20.0
end
end
The latitude/longitude are correctly being geocoded and stored in latitude/longitude. However, when I try:
Market.near(params[:search])
it returns nil.. But, if I just use the lookup => :google it works just as I intend it to. Has anyone got this working before, specifically the near method of geocoder?

Answer 1

I ended up coming back to this on a new project and figured it out.
The docs on geocoder actually state that the hash has to have string keys and not symbols. geocoder docs - see notes
i.e.
before(:each) do
Geocoder.configure(:lookup => :test)
Geocoder::Lookup::Test.add_stub(
"Los Angeles, CA", [{
"latitude" => 34.052363,
"longitude" => -118.256551,
"address" => 'Los Angeles, CA, USA',
"state" => 'California',
"state_code" => 'CA',
"country" => 'United States',
"country_code" => 'US'
}],
)
end
and not how I did it in the original post:
i.e. :latitude => 34.052363
I ended up doing something a bit more dynamic:
# frozen_string_literal: true
module GeocoderStub
def self.stub_with(facility)
Geocoder.configure(lookup: :test)
results = [
{
'latitude' => Faker::Address.latitude.first(9),
'longitude' => Faker::Address.longitude.first(9)
}
]
queries = [facility.full_address, facility.zip]
queries.each { |q| Geocoder::Lookup::Test.add_stub(q, results) }
end
end
and in my factory:
require './spec/support/geocoder_stub'
FactoryGirl.define do
factory :facility do
name { Faker::Company.name }
rating { rand(1..5) }
street { Faker::Address.street_address }
city { Faker::Address.city }
state { Faker::Address.state }
zip { Faker::Address.zip_code }
after(:build) { |facility| GeocoderStub.stub_with(facility) }
end
end
This adds a geocoder stub for every Facility factory that is built for both full address (method defined in facility) and zip.

Answer 2

I found a simpler approach to be just stubbing everything with the same values by default:
# test/test_helper.rb
Geocoder.configure(lookup: :test)
Geocoder::Lookup::Test.set_default_stub([{ coordinates: [40.7143528, -74.0059731] }])
Also, to avoid unnecessary calls, it's also a good idea to restrict your callbacks:
class Account < ActiveRecord
after_validation :geocode, if: ->(obj) { obj.address.present? and obj.address_changed? }
end
