Unit testing

Exercise 0: Writing your first unit test

1. Create a new script with a simple function like mean(data).
2. Write test functions from scratch to assert expected outcome.
3. Import unittest and put these test functions inside a test class.

A solution example is given inside /solutions/exercise0.py.

Exercise 1: The Stack

This repository provides a simple implementation of a stack in Python inside stack.py. This stack offers the following behavior:

• isEmpty – Returns whether the stack is empty.
• push(element) – Inserts the element at the top of the stack.
• pop() – Deletes and returns the topmost element of the stack. Raises an EmptyStackException if trying to pop an empty stack.

The goal of this exercise is to create a test file that documents this behavior.

Solution

You will find a test file template inside /solutions as well as a few valid solutions to this exercise:

• testStackDCC.py : solution written during the DCC-Lab workshop.
• testStack1.py : a reference solution including explanations for some part of the thought-process.
• testStack2.py : a slightly improved version of testStack1.py that uses constants and a setup method.
