我似乎无法以一种不会不时抛出随机错误的方式设置 rspec/capybara。我最常见的错误(但不一致)是:
An error occurred in an after hook
ActiveRecord::RecordNotFound: Couldn't find Post with id=1
occurred at [...]/gems/activerecord-3.2.11/lib/active_record/relation/finder_methods.rb:341:in `find_one'
紧随其后的是与预期模型对象相关的任何事情,这些对象是在规范中创建的,但后来找不到。例如类似的东西
Sorter should populate featured_posts with appropriate posts
Failure/Error: Sorter.top_4.map(&:id).should eq(([best_new_post, best_old_post] + new_posts.last(2).reverse).map(&:id))
expected: [2, 1, 40, 38]
got: []
当我单独运行这些测试时,它们总是会通过,而当我在套件中运行它们时,它们并不总是失败。我假设线程以及数据库的设置方式存在某种问题,但我似乎无法弄清楚。
我spec_helper.rb
是来自各种来源的大杂烩:

require 'spork'
Spork.prefork do

我已经尝试删除部分进行故障排除,但很难判断它是否解决了任何问题,因为错误是零星的。
这里有什么可以作为上述错误的明显原因,或者关于如何解决这个问题的任何建议?
