Crafting Test-Driven Software with Python

By: Alessandro Molina

Overview of this book

Test-driven development (TDD) is a set of best practices that helps developers to build more scalable software and is used to increase the robustness of software by using automatic tests. This book shows you how to apply TDD practices effectively in Python projects. You’ll begin by learning about built-in unit tests and Mocks before covering rich frameworks like PyTest and web-based libraries such as WebTest and Robot Framework, discovering how Python allows you to embrace all modern testing practices with ease. Moving on, you’ll find out how to design tests and balance them with new feature development and learn how to create a complete test suite with PyTest. The book helps you adopt a hands-on approach to implementing TDD and associated methodologies that will have you up and running and make you more productive in no time. With the help of step-by-step explanations of essential concepts and practical examples, you’ll explore automatic tests and TDD best practices and get to grips with the methodologies and tools available in Python for creating effective and robust applications. By the end of this Python book, you will be able to write reliable test suites in Python to ensure the long-term resilience of your application using the range of libraries offered by Python for testing and development.

Summary

In this chapter, we saw how Tox can take care of all the setup necessary to run our tests for us and how it can do that on multiple target environments so that all we have to do to run tests is just to invoke Tox itself.

This is a more convenient, but also robust, way to manage our test suite. The primary benefit is that anyone else willing to contribute to our project won't have to learn how to set up our projects and how to run tests. If our colleagues or project contributors are familiar with Tox, seeing that our project includes a tox.ini file tells them all that they will need to know—that they just have to invoke the tox command to run tests.

Now that we have seen the base plugins and tools to manage and run our test suite, in the next chapter, we can move on to some more advanced topics that involve how to test our documentation itself and how to use property-based testing to catch bugs in our code.
