pytest
======

:doc:`pytest <pytest:index>` is an alternative to Python’s :doc:`../unittest`
module that simplifies testing even further.

Features
--------

* More detailed information about failed ``assert`` statements
* Automatic detection of test modules and functions
* Modular fixtures for the management of small or parameterised, long-lived test
  resources
* Can also execute unit tests without presets
* Extensive plug-in architecture, with over 800 external plug-ins
