Test-Driven Python Development

By: Siddharta Govindaraj

Overview of this book

This book starts with a look at the test-driven development process, and how it is different from the traditional way of writing code. All the concepts are presented in the context of a real application that is developed in a step-by-step manner over the course of the book. While exploring the common types of smelly code, we will go back into our example project and clean up the smells that we find. Additionally, we will use mocking to implement the parts of our example project that depend on other systems. Towards the end of the book, we'll take a look at the most common patterns and anti-patterns associated with test-driven development, including integration of test results into the development process.

Integrating with packaging tools

Packaging refers to how Python packages are generally distributed to users. Unless we are writing proprietary commercial software, we will want to distribute the unit tests along with the code and allow the end user to run the tests and verify that everything is working.

Packaging tools have been one of the most confusing parts of the Python ecosystem. There have been a number of different frameworks that, at different points, have been "the right way" to do things. As this book is being written, setuptools is the recommended way to package Python modules, so let us take a look at that first.


Setuptools supports a test command for running the test suite. All we need to do is to configure it. We do this by specifying the test_suite parameter in as follows:

from setuptools import setup, find_packages


When we do this, setuptools...
