Cucumber steps in different programming languages

gistfile1.txt

>>>> Gherkin <<<<

As a developer
In Order to find the best scripting solution
So that I can compare different implementation languages for Cucumber

Given I have 1h of time
When I write something about Cucumber
Then others should like that


>>>> Ruby <<<<

require 'rspec'

Before do
    @usefulness = 0
end

Given "I have (\d+)h of time" do |time|
    @time = time.to_i
end

When "I write something about (\w+)" do |topic|
    @usefulness = @time * 20 if topic == 'cucumber'
end

Then "others should like that" do
    @usefulness.should >= 20
end
