rspec before(:each) hook - conditionally apply

问题

I have following in my rails_helper.rb:

RSpec.configure do |config|
  # ...
  config.before(:each, type: :controller) do
    # SOMETHING
  end
end

I want to define directories, to which this SOMETHING will be applicable (in my case ONLY to files under spec/controllers/api directory).

Any chance to achieve that?

回答1:

You can use a more specialized name for your RSpec filter:

RSpec.configure do |config|
  # ...
  config.before(:each, :subtype => :controllers_api) do
    # SOMETHING
  end
end

And then in your RSpec examples in spec/controllers/api, you add some metadata:

RSpec.describe "something", :subtype => :controllers_api do
end

This SOMETHING should run only on examples having the :subtype => :controllers_api metadata. I did not use :type because there may be other behavior defined with it.
