Overview of this book

<p>Automated testing moves much of the labor of testing off the developer and makes it easier as well as quicker to find bugs and fix them. Automated tests run faster, increase test coverage, and lower costs. However, testing is neither an easy process nor remotely exciting for most developers. But with the right techniques and tools, testing can become a simple and gratifying part of the development process.<br /><br />With this helpful guide – from an expert – in your hand, testing will not be a tiresome topic for you anymore. You will learn how to test your Python projects in the easiest way, making other parts of the development process easier and more enjoyable. <br /><br />This book covers the tools and techniques of automated testing and test-driven development. Starting from the very basics, the chapters introduce new tools and techniques in simple, accessible language with step-by-step examples. You will explore how to make testing easier and more accurate with Python's doctest module and learn test-driven development using the unittest framework. You will also learn how to keep your units separate from each other and discover a simple and easy way to integrate Mocker and unittest. Next, we cover integration testing and web application testing.<br /><br />Automated testing gives developers better feedback, faster and more often. Bugs get found sooner and fixed better, with less effort. By the end of this book, you will have all of the skills needed to benefit from automated testing.</p>

Summary


We learned the syntax of doctest, and went through several examples describing how to use it. After that, we took a real-world specification for the AVL tree, and examined how to formalize it as a set of doctests, so that we could use it to automatically check the correctness of an implementation.

Specifically, we covered doctest's default syntax, and the directives that alter it, how to write doctests in text files, how to write doctests in Python docstrings, and what it feels like to use doctest to turn a specification into tests.

Now that we've learned about doctest, we're ready to talk about how to use doctest to do unit testing—which is the topic of the next chapter.
