Test applications, packages, and libraries large and small with pytest, Python\'s most powerful Testing framework. pytest 7 supports Python 3.5 and above..
What You Need: The examples in this book were written using Python 3.10 and pytest 7.
Write simple, maintainable tests quickly with pytest.
Extend pytest with plugins, connect it to continuous integration systems, and use it in tandem with tox, mock, coverage, and even existing unittest tests.
Test error conditions and corner cases with expected exception testing, and use one test to run many test cases with parameterized testing.
Move setup code out of tests and into fixtures to separate setup failures from test failures.
Use Python\'s builtin assert statements instead of awkward assert helper functions to make your tests more readable.
Speed up test times by distributing tests across multiple processors and running tests in parallel.
Write short, maintainable tests that elegantly express what you\'re testing.
with Simple step-by-step instructions and sample code, this book gets you up to speed quickly on this easy-to-learn yet powerful tool.
The pytest framework gives you powerful features such as assert rewriting, parametrization, markers, plugins, parallel test execution, and clear test failure reporting - with no boilerplate code. pytest\'s fixture model allows you to share test data and setup procedures across multiple layers of tests.
It\'s a full-featured, flexible, and extensible Testing framework. pytest is undeniably the best choice for Testing Python projects.
This book shows you how.
Using a robust yet Simple fixture model, it\'s just as easy to write small tests with pytest as it is to scale up to complex functional testing.
In this fully revised edition, explore pytest\'s superpowers - Simple asserts, fixtures, parametrization, markers, and plugins - while creating Simple tests and test suites against a small database application. pytest helps you write tests quickly and keep them readable and maintainable.
