Overview

TDD vs BDD

Ruby Testing Frameworks

Test::Unit KH

MiniTest::Unit TG

RSpec KH

Shoulda TG

Cucumber TG

Criteria

  • IDE integration
  • Test output detail
  • Testing constructs available
  • TDD or BDD
  • Documentation
  • Learning curve and ease of use


Framework Matrix

Framework Website Documentation IDE Integration Type Ease of Use
Unit::Test
MiniTest::Unit

Demo Code

 class Account
   @balance
   @name
 
   attr_accessor :balance
   attr_accessor :name
 
   def initialize(amount)
     @balance = amount
   end
 
   def deposit(amount)
     @balance += amount
   end
 
   def addinterest(rate)
     @balance *= (1 + rate)
   end
 
   def withdrawal(amount)
     @balance -= amount
   end
 end


Test::Unit

 require "test/unit"
 require_relative("../Account.rb")
 
 class AccountTest < Test::Unit::TestCase
 
   def test_balance
     a = Account.new(100)
     assert_equal(100, a.balance())
   end
 
   def test_deposit 
     a = Account.new(100)
     assert_equal(200, a.deposit(100))
   end
   
   def test_withdrawal
     a = Account.new(100)
     assert_equal(50, a.withdrawal(50))
   end
   
   def test_name
     a = Account.new(100)
     a.name = "Checking"
     assert_not_nil(a.name())
   end
 
   def test_interest
     a = Account.new(100)
     assert_equal(a.addinterest(0.5), 150)
   end
 
   def test_fail
     a = Account.new(100)
     assert_equal(a.balance(), 200)
   end
 end
