A Simple Example of unittest Module

Let's test a simple example of unittest module.

We'll cover the following...

We always find a code example or two to be the quickest way to learn how something new works. So let’s create a little module that we will call mymath.py. Then put the following code into it:

Press + to interact
def add(a, b):
    return a + b
def subtract(a, b):
    return a - b
def multiply(a, b):
    return a * b
def divide(numerator, denominator):
    return float(numerator) / denominator
print(divide(34,5))
print(add(4,5))
print(subtract(3,4))
print(multiply(3,4))

This module defines four mathematical functions: add, subtract, multiply and divide. They do not do any error checking and they actually don’t do exactly what we might expect. For example, if we were to call the ...
