如何在測試中重新加載燈具

我試圖通過比較動態生成的飼料與已知輸出來測試RSS飼料。爲了使這個工作，我需要加載凍結時間的燈具。下面的工作，但似乎矯枉過正重新加載模式和固定裝置重置數據庫。如何在測試中重新加載燈具

# test/integration/feed_test.rb 
require 'test_helper' 
load 'Rakefile' 

class FeedTest < ActionDispatch::IntegrationTest 
    def setup 
    # Normalize time in order to match fixture file 
    travel_to Time.zone.parse('2015-03-01T12:00:00') do 
     silence_stream(STDOUT) do 
     # anything written to STDOUT here will be silenced 
     Rake::Task['db:schema:load'].reenable 
     Rake::Task['db:schema:load'].invoke 
     end 
     Rake::Task['db:fixtures:load'].reenable 
     Rake::Task['db:fixtures:load'].invoke 
    end 
    end 

    test 'feed matches fixture file' do 
    get feed_path 
    assert_equal contents('feed.atom'), response.body 
    end 
end 

# test/test_helper.rb 
module ActiveSupport 
    class TestCase 
    fixtures :all 

    def contents(file_name) 
     IO.read "test/fixtures/files/#{file_name}" 
    end 
    end 
end

我不知道如何重新加載只是travel_to塊內的項目篩選器。我也無法讓travel_to在test_helper.rb中工作。

但是，這種方法的真正問題是重裝Rakefile導致從secure_headers寶石以下虛假警告：

$ rake test

好像我應該能夠重新加載一些燈具，而無需使用耙子在所有，但我不知道如何這樣做。

您是否嘗試過這個不同版本的Ruby，或許2.3.1或2.2.5？ Ruby 2.3.0被報告爲「越野車」。 –

不幸的是，事實並非如此。我安裝Ruby 2.3.1並獲得相同的消息。 – dankohn

下面是解決我的問題的修補程序：

# frozen_string_literal: true 
require 'test_helper' 
load 'Rakefile' 

class FeedTest < ActionDispatch::IntegrationTest 
    # Turn off transactional fixtures for this test since we are loading 
    # the fixtures database anyway. This will prevent the timestamp change 
    # from spilling into other tests. 
    self.use_transactional_tests = false 

    setup do 
    # Ensure the test db has its environment metadata set to test, 
    # otherwise tasks farther down will fail. New for Rails 5 
    Rake::Task['db:environment:set'].invoke 
    # Normalize time in order to match fixture file 
    travel_to Time.zone.parse('2015-03-01T12:00:00') do 
     ActiveRecord::Schema.verbose = false 
     Rake::Task['db:schema:load'].reenable 
     Rake::Task['db:schema:load'].invoke 
     Rake::Task['db:fixtures:load'].reenable 
     Rake::Task['db:fixtures:load'].invoke 
    end 
    end 

    test 'feed matches fixture file' do 
    get feed_path 
    assert_equal contents('feed.atom'), response.body 
    end 
end
