Question

我还没有找到原因，但我在Rails项目中多次加载共享规范的弃用警告。以下是它们的定义方式：

＃spec / support / shared / authenticated_endpoints_spec.rb

RSpec.shared_examples "an authenticated endpoint" do
  it_behaves_like "an authenticated show endpoint"
  it_behaves_like "an authenticated index endpoint"
end

RSpec.shared_examples "an authenticated show endpoint" do
# omitted
end
RSpec.shared_examples "an authenticated index endpoint" do
# omitted
end

我的spec_helper看起来像这样：

RSpec.configure do |config|
  Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
end

这是我得到的弃权警告：

WARNING: Shared example group 'an authenticated endpoint' has been previously defined at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:1
...and you are now defining it at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:1
The new definition will overwrite the original one.
WARNING: Shared example group 'an authenticated show endpoint' has been previously defined at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:6
...and you are now defining it at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:6
The new definition will overwrite the original one.
WARNING: Shared example group 'an authenticated index endpoint' has been previously defined at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:36
...and you are now defining it at:
  /Users/me/my_proj/spec/support/shared/authenticated_endpoints_shared_spec.rb:36
The new definition will overwrite the original one.

我不需要在测试套件中的任何其他地方（我可以找到，无论如何）找到这些共享规范。我仔细查看了rspec-core，还有许多我不太了解的元编程。

任何人都有关于如何调试它的提示？

Answer 1

我相信原因是here。由于您的文件名以＆＃34; _spec.rb＆＃34;结尾，因此它们会被RSpec自动加载为示例。我做了什么，有什么帮助，重命名文件，包含共享示例，删除＆＃34; _spec＆＃34;部分。

Answer 2

对于此，在rspec-rails上已关闭issue。基本上，RSpec使用模式匹配器（spec/**/*_spec.rb）来查找spec文件并自动加载它们。但您的规范帮助程序会自动加载spec/support/子目录中的所有文件。因此，您的spec/support/shared/authenticated_endpoints_spec.rb文件正在加载两次。

我建议将spec/support/shared/子目录移至spec/shared。

Rspec共享定义加载两次
