SImplecov - 不正确的葡萄API测试覆盖率

我有一个基于葡萄的API的Rails 4.2应用程序。我开始使用Rpsec为它编写测试。我的测试效果很好，测试了我的预期。但是，当我在终端运行rspec时，Simplecov没有显示api文件的正确覆盖范围，如下图所示。SImplecov - 不正确的葡萄API测试覆盖率

上使用dir /lib/api/app该文件确实有一些覆盖。但Simplecov显示他们覆盖0％。

比较，我跑的规格内的RubyMine有内置的覆盖工具，它显示了正确的报道：

所以，我在这里失去了一些东西？ simplecov怎么了？

这是我rails_helper.rb：

ENV['RAILS_ENV'] ||= 'test' 
require File.expand_path('../../config/environment', __FILE__) 

abort("The Rails environment is running in production mode!") if Rails.env.production? 
require 'spec_helper' 
require 'rspec/rails' 
require 'simplecov' 
SimpleCov.start 'rails' 

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f } 


ActiveRecord::Migration.maintain_test_schema! 

RSpec.configure do |config| 

    config.include RSpec::Rails::RequestExampleGroup, type: :request, file_path: /spec\/api\/v1/ 


    config.fixture_path = "#{::Rails.root}/spec/fixtures" 

    config.use_transactional_fixtures = false 


    config.infer_spec_type_from_file_location! 

    Faker::Config.locale = 'pt-BR' 

end

这是API的一个端点，trips.rb：

module Api 
    module App 
    class Trips < Grape::API 
     include Grape::Kaminari 
     resource :trips do 
     desc 'Return a list of trips of a vehicle.' 
     params do 
      requires :vehicle_id, type: Integer, desc: 'id of the vehicle' 
      optional :page, type: Integer, desc: 'Page of registers. Default to 1 (first page).' 
      optional :per, type: Integer, desc: 'Number of registers per page. Default to 25.' 
     end 
     get do 
      vehicle = Vehicle.find params[:vehicle_id] 
      if vehicle.user == current_user 
      trips = Trip.where(vehicle_id: vehicle.id).order(started_at: :desc) 

      present paginate(trips), with: Entities::Trip 
      else 
      error!('Unauthorized', 401) 
      end 
     end 

     desc 'Return a Trip' 
     params do 
      requires :id, type: Integer, desc: 'id of the Trip' 
     end 

     route_param :id do 
      get do 
      trip = Trip.find params[:id] 
      if trip.vehicle.user == current_user 
       present trip, with: Entities::Trip 
      else 
       error!('Unauthorized', 401) 
      end 

      end 
     end 

     end 
    end 
    end 
end

这是一个例子规范，应该是100％覆盖（trips_spec.rb）：

describe Api::App::Trips do 
    include ApiHelpers 

    let(:user)   { create(:user) } 
    let(:user2)   { create(:user) } 
    let(:vehicle)  { create(:vehicle, user_id: user.id) } 
    let(:vehicle2)  { create(:vehicle, user: user2) } 
    let(:trip)   { create(:trip, vehicle: vehicle) } 
    let(:trip2)   { create(:trip, vehicle: vehicle2) } 
    let(:auth_headers) { user.create_new_auth_token } 




    describe 'GET /api/v1/trips/:id' do 

    context 'when not authenticated' do 
     it 'returns 401 unauthorized' do 
     get "/api/v1/trips/#{trip.id}" 
     expect(response).to have_http_status(401) 
     end 
    end 

    context 'when user owns the vehicle' do 

     it 'returns a trip by id' do 
     get "/api/v1/trips/#{trip.id}", nil, auth_headers 
     expect(response.status).to eq(200) 
     expect(json_response).to be_an Hash 
     end 
    end 

    context 'when vehicle is from another user' do 

     it 'returns error 404' do 
     get "/api/v1/trips/#{trip2.id}", nil, auth_headers 
     expect(response.status).to eq(401) 
     end 
    end 

    end 

    describe 'GET /api/v1/trips' do 

    context 'when user owns the vehicle' do 

     it 'returns a list of trips by vehicle id' do 
     get "/api/v1/trips?vehicle_id=#{vehicle.id}", nil, auth_headers 
     expect(response.status).to eq(200) 
     expect(json_response).to be_an Array 
     end 
    end 

    context 'when vehicle belongs to another user' do 
     it 'returns error 404' do 
     get "/api/v1/trips?vehicle_id=#{vehicle2.id}", nil, auth_headers 
     expect(response.status).to eq(401) 
     end 
    end 

    end 

end
