World vs Include in cucumber/ruby

Question

Can anyone tell me the difference between include and World? in my env.rb file I want to expose a module, and I can't really see the difference between the approaches...

Module example:

module Test do
  ...
end

In my env.rb file:

World(Test)

or

include Test

Besides that, can anyone state the pros/cons of using World rather than include in cucumber/ruby?

Answer 1

World(Test) is the preferred method.

The purpose to using World(Test) is that you don't pollute the global namespace yet you still have all the functionality of that module available in your stepdefs.
