Question

我有一个简单的测试来检查carrierwave上传器是否正常工作。

我为此使用minitest，测试在单独运行时有效，但不在Rails的rake test...环境下运行。

（测试代码如下。）

有效的方法：

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

不起作用的事情：

如果我调用rake test test/uploaders/image_file_uploader_test.rb，我会被放入调试器（下面的堆栈跟踪）
如果我致电zeus rake test test/uploaders/image_file_uploader_test.rb我也会被调入

有什么奇怪的：

如果我将调试器中的调用堆栈调到导致失败的测试行 - uploader.store!(@file) - 并直接用(rdb:1) p uploader.store!(@file)调用它，它就可以了！我的意思是，该方法按预期返回，文件出现在正确的目录中。

思考吗

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 - 包括什么东西？是否与Rails环境中的初始化程序有关？（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。）

Rails初始化程序（N.B.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，因为我正在改变代码中的其他内容，包括整个Rails环境，就像我一样。

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，然后在测试中修补这些方法。

令人讨厌的是，基于初始化程序的方法的最初原因是为原始图像拾取了自定义目录，但是对于已处理的版本则没有。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初始化程序

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

（NB包含test_helper与修复无关 - 在我开始工作之后，我将一些require移动到帮助程序，以便与其他测试重叠一些。）

测试通过`testrb`，但使用Rails`rake test`崩溃？
