Fizz Buzz by cyber-dojo

Cyber-dojo foundation (See license): http://www.cyber-dojo.org/.

Write a function that takes numbers from 1 to 100 and outputs them as a string, but for multiples of 3, it returns Fizz instead of the number, and for multiples of 5, it returns Buzz. For numbers that are multiples of both 3 and 5, it returns FizzBuzz.

Tip

Start by writing a failing test. Think about what behaviors your code should implement.

Fizz Buzz – partial walkthrough

Let's first pick the behavior where numbers not divisible by 3 or 5 are returned as a string. Let's start with number 1.

Write a new failing test.

When I fizzbuzz number 1, I get back a string representing it

Use fake it as an implementation strategy.

return "1"

Run the test and make sure it's green.

Write a new failing test since we do not have enough examples to prove the behavior we are implementing yet.

When I fizzbuzz number 2, I get back a string...
