Question

我刚刚发现了Geocoder gem，我的问题与如何通过Rspec测试它的使用有关。正如我在这里看到的How to test geocoder gem

我创建了一个google_data.json来模拟googlemaps响应，以便每次都不会点击他们的API并且不会消耗我的每日请求数量（而且这样测试真的更快）。当我想测试像这样的函数时，我的问题出现了

def self.find_by_radius_from_location(location, radius=10)
  coords = Geocoder.coordinates(location)
  Garage.near(coords, radius, units: :km)
end

这是我的测试（如果我连接到gmaps api就可以使用）

describe 'find_by_radius_from_location' do
let!(:garage_inside_radius) { FactoryGirl.create(:turin_garage) }
let!(:garage_outside_radius) { FactoryGirl.create(:rome_garage) }

  context 'given a city' do
    it 'should return one garage' do
      garages = Garage.find_by_radius_from_location('Torino', 10)
      garages.first.should eq(garage_inside_radius)
      raise garages.inspect
      ids = garages.collect { |g| g[:id] }
      ids.count.should be(1)
    end
  end
end

车库坐标是正确的（如果我连接到gmaps，测试通过）我的json有什么问题，因为我收到2个车库而不是1个车库。这是

{
  "status": "OK",
  "results": [ {
    "types": [ "street_address" ],
    "formatted_address": "Via Monginevro 162, Torino, Italy",
    "address_components": [ {
      "long_name": "Via Monginevro 162",
      "short_name": "Via Monginevro 162",
      "types": [ "route" ]
    }, {
      "long_name": "Torino",
      "short_name": "Torino",
      "types": [ "city", "political" ]
    }, {
      "long_name": "Italy",
      "short_name": "IT",
      "types": [ "country", "political" ]
    } ],
    "geometry": {
      "location": {
        "lat": 45.0647,
        "lng": 7.63015
      }
    }
  }, {
    "types": [ "street_address" ],
    "formatted_address": "Via G. Ferraris 2/4, Roma, Italy",
    "address_components": [ {
      "long_name": "Via G. Ferraris 2/4",
      "short_name": "Via G. Ferraris 2/4",
      "types": [ "route" ]
    }, {
      "long_name": "Roma",
      "short_name": "Roma",
      "types": [ "city", "political" ]
    }, {
      "long_name": "Italy",
      "short_name": "IT",
      "types": [ "country", "political" ]
    } ],
    "geometry": {
      "location": {
        "lat": 41.8084,
        "lng": 12.3015
      }
    }
  } ]
}

这有什么问题？有没有办法测试我的find_by_radius_from_location功能？我想我应该只收到一个车库，但我收到2个......为什么？

修改

我找到了一种解决方法，但也许有更好的方法来实现这一目标。

let!(:garage_inside_radius) { FactoryGirl.create(:turin_garage) }
let!(:garage_outside_radius) { FactoryGirl.create(:rome_garage) }
let(:outside_coords) { { latitude: 41.8084, longitude: 12.3015 } }
before(:each) do
  garage_outside_radius.update_attributes(outside_coords)
end
