我有一个简单的测试来检查carrierwave上传器的工作原理。使用`testrb`测试通过，但使用Rails`rake test`崩溃？

为此，我使用minitest，测试在独立运行时运行，但不在Rails的rake test...环境下运行。

（代码为测试包含下面。）

的事物，它们：

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。
如果我手动调用从IRB测试，代码没有什么预期
如果我创建了一个小耙TestTask运行文件（任务也低于拷贝）的所有行（不 Rails的控制台）测试通过。

东西不起作用：

如果我打电话rake test test/uploaders/image_file_uploader_test.rb我掉下进入调试器（堆栈跟踪下文）
如果我打电话zeus rake test test/uploaders/image_file_uploader_test.rb我也掉下进入调试

奇怪的是：

如果我将调试程序中的调用堆栈抬头到引起失败的测试行 - uploader.store!(@file) - 并直接使用(rdb:1) p uploader.store!(@file)调用它，它将起作用！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？

我可能会在这里做一些非常愚蠢的事情。它必须与加载Rails环境的Rake任务有关，对吧？我是双重的 - 包括东西或其他东西？这与Rails环境中的初始化工具有关吗？（N.B.，当我从调试器执行store!时，它将文件存储在测试中指定的位置，因此它成功覆盖了Rails初始化程序）。

require 'rake/testtask' 

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

Rails初始化器（N.B.我认为测试从此隔绝...）

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，虽然没有通过一个完全科学的过程，因为我正在改变代码中的其他内容，包括整个Rails环境。

当前的工作版本极大地简化了Carrierwave初始化器，将路径定义移动到上传器，然后在测试中猴子修补这些方法。令人烦恼的是，基于初始化器的方法的原始原因是自定义目录被拾取为原始图像，但不是处理版本。这似乎现在工作得很好，但是这个当前的代码与旧的代码有什么不同，我不确定。

Rails的初始化

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

上传

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：列入的test_helper是不相关的修复 - 我有它的工作后，我搬到require的一些帮助干燥与其他测试一些重叠。）
