Automated tests are a very important tool in a developer's tool belt. Having a set of automated tests not only increases productivity and software quality; it also works as a safety net for developers and gives confidence in relation to code refactorings. Python comes with a standard unittest module that is used to write automated tests, but there's an alternative: pytest. The pytest framework is simple to get started with, and scales from simple unit tests all the way through to complex integration testing. It is considered by many to be truly Pythonic in its approach, with simple functions, plain asserts, fixtures, plugins, and a whole plethora of features. More and more developers are adopting a full testing approach, so why not use a framework that is both simple and powerful and considered by many to be a true joy to use?

Overview of this book
Python's standard unittest module is based on the xUnit family of frameworks, which has its origins in Smalltalk and Java, and tends to be verbose to use and not easily extensible.The pytest framework on the other hand is very simple to get started, but powerful enough to cover complex testing integration scenarios, being considered by many the true Pythonic approach to testing in Python.
In this book, you will learn how to get started right away and get the most out of pytest in your daily work?ow, exploring powerful mechanisms and plugins to facilitate many common testing tasks. You will also see how to use pytest in existing unittest-based test suites and will learn some tricks to make the jump to a pytest-style test suite quickly and easily.
