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.

In this chapter, you looked at nose2, a powerful test runner and plugin suite, that extends the unittest framework. nose2 can be used as a drop-in replacement for the unittest test runner. It can also be used to extend unittest functionality with useful plugins. Finally, it can be used to write new types of tests such as function tests, parameterized tests, generated tests, and layer-based tests. nose2 also supports configuration files, so it can be run consistently between developers as well as integrating well with automation tools.

In the next chapter, you will take a look at some more advanced testing patterns.
