我有一个简单的测试来检查载波上传器是否工作。

我为此使用了 minitest，并且该测试在单独运行时有效，但不在 Railsrake test...环境下。

（测试代码如下。）

有效的东西：

  • 如果我运行ruby test/uploaders/image_file_uploader_test.rb测试通过。
  • 如果我运行testrb test/uploaders/image_file_uploader_test.rb测试通过。
  • 如果我从 IRB（而不是Rails 控制台）手动调用测试中的所有行，代码会执行预期的操作
  • 如果我创建一个小的 Rake TestTask 来运行文件（任务也在下面复制），则测试通过。

不起作用的事情：

  • 如果我打电话rake test test/uploaders/image_file_uploader_test.rb，我会进入调试器（下面的堆栈跟踪）
  • 如果我打电话zeus rake test test/uploaders/image_file_uploader_test.rb，我也会进入调试器

有什么奇怪的：

如果我将调试器中的调用堆栈指向导致失败的测试行uploader.store!(@file)——并直接使用 调用它(rdb:1) p uploader.store!(@file)，它就可以工作！我的意思是，该方法按预期返回，并且文件出现在正确的目录中。

想法？

我可能在这里做一些非常愚蠢的事情。一定是和 Rake 任务加载 Rails 环境有关吧？我是双重包括东西还是什么？它与 Rails 环境中的初始化程序有关吗？（注意，当我store!从调试器执行时，它会将文件存储在测试中指定的位置，因此它成功地覆盖了 Rails 初始化程序）。

简单的耙子任务

require 'rake/testtask'

Rake::TestTask.new('dev:test') do |t|
  t.test_files = FileList['test/uploaders/*_test.rb']
end

Rails 初始化程序（注意，我认为测试与此隔离......）

CarrierWave.configure do |config|
  config.storage = :file

  # Override the directory where uploaded files will be stored.
  config.store_dir = -> do
    if model.nil?
      "uploads/other/#{Time.now.strftime("%F")}/#{Time.now.strftime("%H-%M-%S")}"
    else
      # This is a sensible default for uploaders that are meant to be mounted:
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end
  end

  # Override the directory where temp files will be stored.
  config.cache_dir = -> do
    # This is a better default because it prevents temp files from becoming public and is more consistent with the Rails directory structure.
    Rails.root.join('tmp/uploads')
  end
end

谢谢！

我已经解决了这个问题，虽然不是通过一个完全科学的过程，因为我正在更改代码中的其他内容，包括整个 Rails 环境，随着我的进行。

当前的工作版本大大简化了 Carrierwave 初始化程序，将路径定义移动到上传程序，然后在测试中对这些方法进行猴子修补。

令人讨厌的是，基于初始化方法的最初原因是为原始图像选择了自定义目录，而不是为处理后的版本选择了自定义目录。现在这似乎工作正常，但我不确定这个当前代码与旧代码有何不同。

Rails 初始化程序

CarrierWave.configure do |config|
  config.storage = :file
end

上传者

class ImageFileUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick

  version :thumbnail do
    process resize_to_fill: [100,100]
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

  def store_dir
    if model.nil?
      "uploads/other/#{Time.now.strftime("%F")}/#{Time.now.strftime("%H-%M-%S")}"
    else
      # This is a sensible default for uploaders that are meant to be mounted:
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end
  end

  def cache_dir
    # This is a better default because it prevents temp files from becoming public and is more consistent with the Rails directory structure.
    Rails.root.join('tmp/uploads')
  end

end

测试

require_relative '../test_helper'
require 'rmagick'
require 'carrierwave'
require_relative '../../app/uploaders/image_file_uploader'

class ImageFileUploaderTest < MiniTest::Unit::TestCase

  # Before any tests run, set up parameters.
  FILENAME = 'test_photo_1.jpg'
  STORE_DIR = 'tmp/uploads/store'
  CACHE_DIR = 'tmp/uploads/cache'
  STORE_PATH = File.join __dir__, '..', '..', STORE_DIR
  CACHE_PATH = File.join __dir__, '..', '..', CACHE_DIR

  # Override the store and cache dirs so we’re not reliant on Rails.
  class ::ImageFileUploader
    storage :file
    def store_dir; STORE_PATH; end
    def cache_dir; CACHE_PATH; end
  end

  # Before each test runs, set up a file to test with.
  def setup
    @file = File.new "#{__dir__}/../test_files/#{FILENAME}"
  end

  # After each test runs, clear the results directory so it doesn't influence other tests.
  def teardown
    FileUtils.rm_rf STORE_PATH
    FileUtils.rm_rf CACHE_PATH
  end

  # The whole point of this is to upload a file.
  def test_upload_of_file
    uploader = ImageFileUploader.new
    uploader.store!(@file)
    # Ensure the uploaded file is correct.
    assert_equal Digest::SHA2.file(@file).hexdigest, Digest::SHA2.file("#{STORE_PATH}/#{FILENAME}").hexdigest
  end

  # After each test, there is nothing to clean up, as teardown clears the output dir.
  def after_tests
  end

end

（注意，包含的test_helper内容与修复无关——在我让它工作后，我将一些requires 移到了 helper 上，以干燥与其他测试的一些重叠。）
