Problem Statement


def fizzbuzz(number: int) -> str:
if number % 15 == 0:
return "Fizz Buzz"
if number % 3 == 0:
return "Fizz"
if number % 5 == 0:
return "Buzz"
return str(number)

Unit Tests

from fizzbuzz import fizzbuzzdef test_3():
assert fizzbuzz(3) == "Fizz"
assert fizzbuzz(6) == "Fizz"
assert fizzbuzz(9) == "Fizz"
assert fizzbuzz(12) == "Fizz"
def test_5():
assert fizzbuzz(5) == "Buzz"
assert fizzbuzz(10) == "Buzz"
assert fizzbuzz(20) == "Buzz"
def test_15():
assert fizzbuzz(15) == "Fizz Buzz"
assert fizzbuzz(30) == "Fizz Buzz"
assert fizzbuzz(45) == "Fizz Buzz"
def test_number():
assert fizzbuzz(1) == "1"
assert fizzbuzz(2) == "2"
def test_edge_cases():
assert fizzbuzz(-1) == "-1"
assert fizzbuzz(3 ** 20) == "Fizz"
assert fizzbuzz(-(3 ** 20)) == "Fizz"
assert fizzbuzz(0) == "Fizz Buzz"
