This document discusses test-driven development and behavior-driven development. It provides examples of writing tests and features in RSpec and Cucumber to define requirements and document software behavior. Code examples show how to structure tests and implement test code. The document emphasizes writing expressive test and feature names, treating tests as documentation, and using a given-when-then structure to define steps. It recommends starting with RSpec book, Kent Beck videos, and e-Genial BDD course.

61. # language: en
Feature: Addition
In order to avoid silly mistakes
As a math idiot
I want to be told the sum of two numbers
Scenario Outline: Add two numbers
Given I have entered 10
And I have entered 5
When I press add
Then the result should be 15

62. Before do
@calc = Calculator.new
end
Given /I have entered (d+)/ do |n|
@calc.push n.to_i
end
When /I press (w+)/ do |op|
@result = @calc.send op
end
Then /the result should be (.*)/ do |result|
@result.should == result.to_f
end
