Action macro for RSpec (very useful for controller specs)

macros.rb

module RSpec
  module Macros
    def action(&block)
      before do |example|
        if example.metadata.fetch(:action, true)
          instance_eval(&block)
        end
      end
    end
  end
end

RSpec.configure do |config|
  config.extend RSpec::Macros
end

spec.rb

action do
  post :create
end
    
it 'does something' do
  # action will be triggered before
end
    
it 'does something', action: false do
  # action won't be triggered before
end
