Test the Fibonacci separated

Just as in the previous case, we can separate the test-cases into separate functions. Soon we’ll see the real value of this separation.

import unittest
from fibonacci import fib

class TestFibo(unittest.TestCase):

    def test_7(self):
        self.assertEqual(fib(7), 8)

    def test_10(self):
        self.assertEqual(fib(10), 34)

    def test_42(self):
        self.assertEqual(fib(42), 165580141)

$ python -m unittest test_fibonacci_with_unittest_separated.py
