Ruby on rails 3 黄瓜“--“格式进度”；不'；行不通

在my cucumber.yml中，我尝试添加此选项（

default:--drb--format progress

），但它返回一个错误：

Exception encountered: #<ArgumentError: wrong number of arguments (3 for 2)
Error creating formatter: progress>

所以也许没有选择，但是

“格式漂亮”在没有任何括号的情况下工作正常。 我不希望看到控制台中的所有场景，但只希望看到哪个场景有错误，也许有另一种方法可以做到这一点

完整跟踪：

如果我在cucumer.yml中写入选项，则错误略有不同：

顺便说一句，我有点小毛病，可能是个问题

从粘贴的输出来看，在

cucumber.yml

文件中有一个额外的角度（'>'）括号：

require 'cucumber/formatter/progress'

创建格式化程序时出错：进度>

除非您的问题中有输入错误，否则Cucumber出于某种原因正在尝试创建名为“progress>”的格式化程序，因此您可能只需要找到并删除额外的尖括号

---

---

编辑：这根本不是问题所在，请参见

根据您问题中的更新信息，我想我看到了问题所在（因此我发布了另一个答案，因为它与我的另一个答案完全不同）。Cucumber似乎正在尝试实例化一个ActiveRecord类，因此我怀疑您的项目中某处有一个名为“Progress”的模型，Cucumber试图创建该模型，而不是实际的格式化程序

通过将此类添加到“支持”文件夹中，我可以重现您的问题（无论如何，已经足够接近了）：

class Progress
    def initialize
        raise "I don't exist!"
    end
end

根据文档，您应该能够在此处指定一个完全限定的类名，即

--format Cucumber:：Formatter:：Progress

，以强制cumber使用自己的格式化程序。然而，我尝试了这个，但仍然不起作用，Cucumber解析完全限定名的方式似乎有一个bug

我可以通过将这一行添加到我的

env.rb

文件中来解决这个问题：

require 'cucumber/formatter/progress'

这样我就可以成功地运行

cucumber--format progress

---

我认为，由于

env.rb

在任何其他代码之前执行，Cucumber的

Progress

类将是创建格式化程序时找到的第一个类。

没有

，我在控制台中尝试了“Cucumber--格式化进度”，但它也不起作用。您可以添加

--backtrace

参数吗
