STDIN gets method issue with rspec

Hi,

I am new to rspec. I am trying to write a spec for a simple ruby program i.e

class First

def test

a = gets.chomp

return a

end

end

I have tried in different ways test method is called from the spec file. but gets.chomp is not executing…

Please kindly advise me, how to write spec for this.

Thanks

Gokul
