What is Unit Testing - According to wikipedia, unit testing is a software testing method by which individual units of source code are tested to determine whether they are fit for use.

Why Unit Test? -
Tests Reduce Bugs in New Features and Existing Features
Tests Are Good Documentation
Tests Reduce the Cost of Change
Faster Debugging
Faster Development
Better Design

Python Testing frameworks
unittest - In the Python Standard Library
nose - Not in the Standard Library. Simpler tests than unittest
pytest - Not in the Python Standard Library.
