Odd or even?

Report a typo

There is a function called is_even(). We do not know its code, but we know exactly how it works — given an integer, it returns True if the number is even, and False if the number is odd. Write tests for this function (use assertTrue and assertFalse).

In this Code Challenge, you do not need to import the module with the function in the beginning of the code. To call the function, just type its name, is_even().

Write a program in Python 3
# tests for the is_even() function
import unittest


class TestIsEven(unittest.TestCase):

def test_when_output_true(self):
# write your tests here

def test_when_output_false(self):
# write your tests here


if __name__ == '__main__':
unittest.main()
