Kata to practice TDD

Write a function that returns for a given number from 1 to 100 this given number, except that :

• For multiples of 3 returns “Fizz”
• For the multiples of 5 returns “Buzz”
• For numbers which are multiples of both 3 and 5 returns “FizzBuzz”

Start by thinking about cases

• Identify test cases
• How would you name your first test ?
  • Write on a Sticky note what would be the name of your first test
  • Compare the different styles
  • What do you prefer / why (Dot voting)

Too easy ?

• Remove “if” in your code
• Parameterize your FizzBuzz, implement this method :
  • int limit : 100
  • int fizz : 3
  • int buzz : 5
• Extend your program
  • Multiples of 7 are “Whizz”
  • Multiples of 11 are “Bang”
• Create a Higher Order Function (fizzBuzz function takes an action function in args)
• Add a voice output
• Write it in an unknown language (still by using TDD)
• ...

Reflect

What happened to your code when implementing new tests ?
