ruby-on-rails – Rails和RSpec：`rake spec`运行所有规格两次

rake spec

我已经找到了一些其他(旧的)问题,但无法为我找到解决方案.我该如何尝试调试？运行rspec就像一个魅力,但我很想知道这里有什么问题.

这是我的spec_helper.rb：

这是原始的Rails项目：

更新

我发现规范rake任务似乎被定义了两次(注意/分隔每个任务的描述)：

$rake -T | grep spec
...
rake spec                               # Run all specs in spec directory (excluding plugin specs) / Run RSpec code examples
...

其中一个是在spec目录中运行所有规范(不包括插件规范),一个是运行RSpec代码示例.

运行RSpec代码示例似乎来自rspec/core/rake_task.rb.运行spec目录中的所有规范(不包括插件规范)似乎来自rspec/rails/tasks/rspec.rake.

在我看来,只有其中一个应该存在？！

更新2

rspec-rails在测试和开发组中似乎都存在问题.我在这里添加了一个问题：https://github.com/rspec/rspec-rails/issues/904
