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>

Basic doctest


Doctest will be the mainstay of your testing toolkit. You'll be using it for tests, of course, but also for things that you may not think of as tests right now. For example, program specifications and API documentation both benefit from being written as doctests and checked alongside your other tests.

Like program source code, doctest tests are written in plain text. Doctest extracts the tests and ignores the rest of the text, which means that the tests can be embedded in human-readable explanations or discussions. This is the feature that makes doctest so suitable for non-classical uses such as program specifications.
