ruby - Is there a cucumber hook to run before and after each feature

Question

Is there a way to run specific code block before and after each cucumber feature with certain tag?

Since setup process is very expensive I don't want to run it before each scenario.

Answer 1

LukasMac's answer didn't work with @ variable. Ande based on official cucumber wiki page, my example below worked and tested ok, the before hook below only execute once per feature:

Before('@my_feature_tag') do
  unless $dts_test_preparation_done
    # expensive setup in my case setup lots of database tables for test
    $dts_test_preparation_done = true
  end
end
