类似于SimpleCov 计算用户模型的 0% 覆盖率，但没有乐趣。

我相信（/希望？）我正在遵循希望将 Spring 与 SimpleCov 一起使用中的建议？.

随着“加载并启动 simplecov”代码在spec/rails_helper.rbSpring 下运行，我的User类在加载devise_forsimplecovroutes.rb之前被加载。

在没有 Spring 的情况下运行 -例如，$ rspec- 一切都很好。

我缺少什么让它在 Spring 下工作？

  • ruby 2.2.1p85（2015-02-26 修订版 49769）[x86_64-darwin15]
  • simplecov 0.12.0
  • 导轨 4.2.5
  • 春天 1.6.3
  • 设计 3.5.6
  • factory_girl 4.5.0
  • factory_girl_rails 4.6.0

spec/rails_helper.rb：

ENV['RAILS_ENV'] ||= 'test'

if ENV['RAILS_ENV'] == 'test'
  puts 'loading simplecov'
  require 'simplecov'
  SimpleCov.start 'rails'
end

require File.expand_path('../../config/environment', __FILE__)
[...]

app/models/user.rb

class User
  puts 'loading User'
  puts caller
  [...]

config/routes.rb：

Rails.application.routes.draw do
  scope '(:locale)', locale: /en|es/ do
    root to: 'home#index'

    devise_for :users # this is line 6

输出：

$ spring stop; spring rspec
Spring is not running

我手头的 Rails 项目有这个问题。（直到现在我才注意到，因为我总是使用 rake 作为 RSpec + Cucumber 套件的一部分运行规范，并且 rspec rake 任务分叉，它逃避了 spring 完成的类加载。使用rake spec不会是你的一个好的解决方案问题，因为分叉否定了弹簧的速度提高。）该项目不使用设计。在那个项目中，这个问题是由两件事引起的：

  1. 在测试环境中急切加载类

    我config.eager_load = true在我的config/environments/test.rb（以便未使用的类会出现在覆盖结果中）。我把它改成了false. spring rspec覆盖范围有所改善，但仍不是应有的水平。

    请注意，注释掉config.eager_load = true叶子eager_load nil，它被视为true. 不得不说清楚false。

    另请注意，simplecov 还建议设置config.serve_static_files = false. 这对我的项目没有任何影响。

  2. 工厂女工

    加载模型时的回溯包括以下几行：

    <gems path>/factory_girl-4.7.0/lib/factory_girl/find_definitions.rb:15:in `find_definitions'
<gems path>/factory_girl_rails-4.7.0/lib/factory_girl_rails/railtie.rb:21:in `block in <class:Railtie>'

    我从 factory_girl_rails 中评论了以下内容lib/factory_girl_rails/railtie.rb

    # config.after_initialize do
#   FactoryGirl.find_definitions
# 
#   if defined?(Spring)
#     Spring.after_fork { FactoryGirl.reload }
#   end
# end

    并在之后立即添加FactoryGirl.find_definitions到我的。然后正确收集覆盖范围。rails_helper.rbrequire 'simplecov'spring rspec

    这部分问题似乎是 factory_girl 设计的结果。我不知道比修改 factory_girl 更好的解决方案。

请注意，类似的问题是由其他类型的早期类加载引起的。有时解决方案是在 config/spring.rb 中启动 simplecov。这对我的项目不起作用。如果您不急于加载测试或使用 factory_girl 这可能是您的解决方案。
