Cucumber Suite Hooks

Adding hooks that run before and after your RSpec test suite looks like this:

# spec/helper/spec_helper.rb

RSpec.configure do |config|
  config.before(:suite) do
    My::Service.build!
  end

  config.after(:suite) do
    My::Service.tear_down!
  end
end

But for Cucumber, the API isn't quite as obvious. I found some interesting discussion online about this subject, and eventually settled on the following:

# features/support/env.rb

My::Service.build!

at_exit do
  My::Service.tear_down!
end

Anything in features/support/env.rb gets run before the Cucumber test suite, so the first method call functions like a before suite block. at_exit is Ruby Kernel and runs when the program exits. This implementation works roughly the same as a before and after block.
