Python Testing with pytest

Python Testing with pytest: Simple, Rapid, Effective, and Scalable, 2nd Edition, teaches developers how to test Python applications, packages, and libraries using the pytest framework.

The volume demonstrates core capabilities such as built-in assert statements, fixtures, parametrization, markers, and plugins. Readers examine these concepts while writing tests against a sample database application without unnecessary boilerplate code.

The 2022 edition provides code examples written with Python 3.10 and pytest 7. It shows how to move setup routines into fixtures, distribute tests across multiple processors in parallel, and incorporate pytest alongside tools like tox, mock, coverage, and unittest.
