ruby - 为什么这个 rspec 测试会为 nil :NilClass"error? 抛出一个 "undefined method ` 调用

Question

我正在尝试将 rspec_api_documentation (https://github.com/zipmark/rspec_api_documentation) 集成到我的 sinatra 应用程序中。我遇到了下面的错误。我显然已将错误简化为一个简单的测试，因为我认为一旦我弄清楚配置中的错误，一旦重新集成到我的更大的应用程序中它就会工作。

谢谢!

在 app.rb 中:

require 'rubygems'
require 'sinatra'

get '/index' do
  "hewoah!"
end

在 spec.rb 中:

require "rspec_api_documentation"
require "rspec_api_documentation/dsl"

RspecApiDocumentation.configure do |config|
#  config.app = App
end

resource "Users" do
  get "/index" do
    example "Returns text" do
      do_request
      status.should be_ok
    end
  end
end

rspec spec/acceptance/spec.rb --require ./app.rb的结果 F

要注册您的裸应用程序，您需要将应用程序设置为 Sinatra::Application:

specApiDocumentation.configure do |config|
#  config.app = App 
end

收件人:

specApiDocumentation.configure do |config|
   config.app = Sinatra::Application
end
