Hi, how do i write a test, to Test for the default behavior (of a method ) of printing a range that we give it?

import unittest
from app.logic import FizzBuzzService


class FizzBuzzServiceTestCases(unittest.TestCase):
    def setUp(self):
        """
        Create an instance of fizz_buzz_service
        """
        self.fizzbuzz = FizzBuzzService()

    def test_it_prints_a_range_of_numbers(self):
        """
        Test for the default behavior of printing the range that we give fizz_buzz_service
        """
        pass
class FizzBuzzService:
    def print_range(self, x, y):
        for i in range(x, y):
            print(i)

Tried this but still some guidance

class FizzBuzzService:
    def print_number(self, num):
        for i in range(num):
            print(i, end=' ')
import unittest
from app.logic import FizzBuzzService


class FizzBuzzServiceTestCases(unittest.TestCase):
    def setUp(self):
        """
        Create an instance of fizz_buzz_service
        """
        self.fizzbuzz = FizzBuzzService()

    def test_it_prints_a_number(self):
        """
        Test for the default behavior of printing the range that we give fizz_buzz_service
        """
        number_range = range(10)
        self.assertEqual(self.fizzbuzz.print_number(10), print(*number_range))
