Topic: The Cucumber book test 1

i am doing this tutorial on the "The Cucumber book"  and my test is failing

features/step_definitions/calculator_steps.rb 

Given /^the input "([^"]*)"$/ do |input|
  @input = input
end

When /^the calculator is run$/ do
  @output = `ruby calc.rb #{@input}`
  raise('Command failed!') unless $?.success?
end

Then /^the output should be "([^"]*)"$/ do |expected_output|
  @output.should == expected_output
end

features/adding.feature

Feature: Adding

  Scenario: Add two numbers
    Given the input "2+2"
    When the calculator is run
    Then the output should be "4"

calc.rb

print "4"

Re: The Cucumber book test 1

If should is not a method then rspec is not being loaded properly for some reason.

Re: The Cucumber book test 1

i installed rvm by adding a .rvmrc file with this code

#!/usr/bin/env bash

environment_id="ruby 1.9.3-p194@calculator"

if [[ -d "${rvm_path:-$HOME/.rvm}/environments" \
  && -s "${rvm_path:-$HOME/.rvm}/environments/$environment_id" ]] ; then
  \. "${rvm_path:-$HOME/.rvm}/environments/$environment_id"
else
  # If the environment file has not yet been created, use the RVM CLI to select.
  rvm --create  "$environment_id"
fi

and added a Gemfile 

source 'https://rubygems.org'

  gem 'bcat'
