Rspec С Использованием Базы Данных Разработки

Я использую Rails 4.2 с Ruby 2.2 и rspec для тестовых наборов. Я установил

Rails.env = 'test'

в моей spec_helper и rails_helper. Вот моя база данных.файл yml:

development:
  adapter: postgresql
  encoding: unicode
  database: app_dev
  pool: 5
  username: postgres
  password: root

test:
  adapter: postgresql
  encoding: unicode
  database: app_test
  pool: 5
  username: postgres
  password: root

production:
  adapter: postgresql
  encoding: unicode
  database: app_prod
  pool: 5
  username: postgres
  password: root

вот мой rails_helper:

Rails.env = 'test'
require 'spec_helper'
require File.expand_path('../../config/environment', __FILE__)
require 'rspec/rails'
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|
  config.include JsonHelper
  config.include PathHelper
  config.include S3Helper
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_spec_type_from_file_location!
end

приложение.rb:

require File.expand_path('../boot', __FILE__)

require 'rails/all'
require 'yaml'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module AppName
  class Application < Rails::Application
    config.generators do |g|
      g.assets = false
      g.helper = false
      g.views = false
    end

    # Load all locale files
    config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}')]
    config.i18n.load_path += Dir[Rails.root.join(
                              'config', 'locales', '**', '**', '*.{rb,yml}')]
    config.autoload_paths += %W(#{config.root}/lib)
    config.autoload_paths += Dir["#{config.root}/lib/**/"]
    config.autoload_paths += Dir["#{config.root}/app/workers/"]
    config.action_controller.include_all_helpers = false
    config.active_record.schema_format           = :sql
    config.i18n.available_locales = [:en, :hi, :mr]
    config.i18n.default_locale = :hi
    config.i18n.fallbacks = [:en]
    config.active_record.raise_in_transactional_callbacks = true
  end
end

когда я запускаю свои тестовые случаи, рельсы.env-это "тест", как и ожидалось (используется pry для проверки). однако мои тестовые случаи всегда поражают разработка баз данных.

Rails.env
#=> "test"

ActiveRecord::Base.connection_config
#=> {:adapter=>"postgresql", :encoding=>"unicode", :database=>"app_dev", :pool=>5, :username=>"postgres", :password=>"root"}

spec_helper:

require File.expand_path('../../config/environment', __FILE__)
require 'rspec/rails'
require 'simplecov'
require 'simplecov-rcov'
require 'database_cleaner'
require 'factory_girl_rails'

ENV['RAILS_ENV'] ||= 'test'
SimpleCov.start

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
  # Database Cleaner
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
    Rails.application.load_seed
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end
end

SimpleCov.formatter = SimpleCov::Formatter::RcovFormatter

я чешу голову с последних нескольких часов, но ничего не решает загадку. Любая помощь была бы замечательной!
