Testing

Check if your function returns the expected value using the cell below.

import unittest

class UnitTests(unittest.TestCase):

        self.assertEqual(len(dec_to_binary(100)), 7, 'The function should return a string with lenght=7')
    def test_result_odd(self):
        self.assertEqual(dec_to_binary(101), '1100101', 'The binarie for 200 should be 1100101')
