rspec 堆栈级别太深 [英] rspec stack level too deep

问题描述

当我分别运行模型规格和控制器规格时，没问题.当我一起运行它们时，我得到了堆栈溢出，字面意思是 :)

When I run my model specs and controller specs separately, it's fine. When I run them together, I get a stack overflow, literally :)

$ bundle exec rspec --fail-fast spec/models
........

Finished in 0.44274 seconds
8 examples, 0 failures

$ bundle exec rspec --fail-fast spec/controllers
..

Finished in 0.99339 seconds
2 examples, 0 failures

$ bundle exec rspec --fail-fast spec
F

Failures:

  1) HerpController derp derp example
     Failure/Error: Unable to find matching line from backtrace
     SystemStackError:
       stack level too deep
     # /Users/jared/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.2.1/lib/abstract_controller/layouts.rb:359

我该如何开始调试?谢谢.

How do I even begin to debug this? Thanks.

推荐答案

一次删除一半的规范出现了问题.我想这是二等分调试的一个例子.感谢 Frederick Cheung，他的评论建议了这种方法.

Removing half of my specs at a time turned up the problem. I suppose this is an example of bisect debugging. Thanks to Frederick Cheung, whose comment suggested this approach.

对于后代来说，这就是问题所在.

For posterity, this was the problem.

include Rails.application.routes.url_helpers
describe "Attendee#next_page" do
end

显然，包括进入describe

describe "Attendee#next_page" do 
  include Rails.application.routes.url_helpers
end

关于rspec，我有很多东西要学习.:)

I have a lot to learn about rspec. :)
