Simple Example using Unit Testing in Python

This is simple example how to use unit testing in python. For example, you want to create module that generate fibonacci numbers and want to test whether the module is working properly or not.

Below is simple fibonacci.py script for module to generate fibonacci numbers :

# Fibonacci numbers module
def fib2(n): # return Fibonacci series up to n
    result = []
    a, b = 0, 1
    while b < n:
        a, b = b, a+b
    return result

def main():
    print fib2(100)

if __name__ == '__main__' : main()

And here simple testfibo.py script to test that module:

import fibonacci
import unittest

class TestFibonacciFunctions(unittest.TestCase):

    def test_series_100(self):
        print('\nTest Series 100')
        wanted_result = [1,1,2,3,5,8,13,21,34,55,89]
        test_result = fibonacci.fib2(100)

    def test_series_50(self):
        print('\nTest Series 50')
        wanted_result = [1,1,2,3,5,8,13,21,34]
        test_result = fibonacci.fib2(50)

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

Run testfibo.py script with command

python testfibo.py

You will get following output if the wanted_result and test_result are equal

Test Series 100
Test Series 50
Ran 2 tests in 0.000s
