Test if exception is thrown from a function that accepts user input

For an assignment I am trying to test whether a ValueError exception is raised depending on user input

Here is my program that I am testing:

def prompt_num_integers():
    while True:
        try:
            # converting to int raises ValueError if input can't convert
            num_of_integers = int(input("How many integers do you want to store: "))
            if num_of_integers < 1:
                raise ValueError
        except ValueError:
            print("Sorry, I didn't quite understand that.")
            continue
        else:
            return num_of_integers


def prompt_integers():
    # prompt user for number of integers then store that value into a variable
    num_of_integers = prompt_num_integers()
    # list for storing the integers
    integer_list = []
    # integer for keeping count of current num of integers
    x = 0
    while x < num_of_integers:
        try:
            # check if current num of integer equals total num of integers wanted, then give appropriate prompt
            if x == num_of_integers - 1:
                integer = int(input("Input last integer: "))
            else:
                integer = int(input("Input integer: "))
        except ValueError:
            print("Sorry, I didn't quite understand that.")
            continue
        else:
            # add correct integer to integer list, then update current num of integers variable
            integer_list.append(integer)
            x += 1

    print(f"List of integers: {integer_list}")
    return integer_list

And here is my unit test:

import unittest
import unittest.mock as mock

import GatheringInputFunctionsKing as Test


class MyTestCase(unittest.TestCase):
    def test_a_function_throws_exception(self):
        with mock.patch('builtins.input', side_effect=[0,1,1]):
            self.assertRaises(ValueError, Test.prompt_integers)

Even when testing just the function prompt_num_integers, I get the same result... The test just results with FAILED:
