The standard workflow while using unittest is: derive your own class from unittest.TestCase write your tests in functions which start with test_ finally write unittest.main() at the end of your file to run the tests I was also used to be scared by testing. Testing seemed to me as something from outer space but now I have learned its importance and it is essential for every programmer to learn it. A simple script So lets write a simple script which we can later test. This script is going to do some math functions for us. So here is the script: # save it as math.py def multiply(n1, n2): return n1 * n2 def add(n1, n2): return n1 + n2 So thats our little script. Now lets move forward and write our first test.
