Question

我试图运行一个capybara cookie功能规范，当我调用visit [URL]方法时，堆栈跟踪会给我以下错误。

Failures:

  1) Cookie Configuration writes cookies
     Failure/Error: visit('/cookies')
     NoMethodError:
       undefined method `[]=' for nil:NilClass

我怀疑的部分问题是actionpack-4.0.13/lib/action_dispatch/request/session.rb我们有代码：

def self.find(env)
  env[ENV_SESSION_OPTIONS_KEY]
end

返回nil，因为我认为env [ENV_SESSION_OPTIONS_KEY]没有设置。并且因为它在调用时返回nil：

def load!
   id, session = @by.load_session @env
   options[:id] = id
   @delegate.replace(stringify_keys(session))
   @loaded = true
end

options[:id]给出了上面的堆栈跟踪中看到的错误。

这是我手动在测试中必须存根的东西吗？我可能缺少一种配置吗？

编辑：如果你想查看规范代码，那就相当简单了：

require 'spec_helper'

describe 'Cookie Configuration', type: :feature do
  it 'writes cookies' do
    visit('/cookies')
    ..
  end
end

Env [ENV_SESSION_OPTIONS_KEY]的ActionDispatch nil值
