# FizzBuzz: Not-Divisible Requirement

Add test scenarios to our FizzBuzz kata to better understand how to apply TDD.

As a reminder, let’s recap the rules of the `FizzBuzz`

kata. It’s a function that accepts a number as the input and returns a string depending on the following conditions:

- If the number is divisible by three, it returns
`Fizz`

. - If the number is divisible by five, it returns
`Buzz`

. - If the number is divisible by three and five, it returns
`FizzBuzz`

. - If the number is neither divisible by three nor by five, it returns a string representation of that number.

So far, we managed the most trivial example which used `1`

as the input argument. Now, let’s add more tests for the fourth requirement.

## Passing `2`

to the `FizzBuzz`

function

Let’s start with a simple scenario for the `FizzBuzz`

function, which consists of passing the value `2`

to it.
