pytest: helps you write better programs
=======================================
.. module:: pytest
The ``pytest`` framework makes it easy to write small, readable tests, and can
scale to support complex functional testing for applications and libraries.
``pytest`` requires: Python 3.8+ or PyPy3.
**PyPI package name**: :pypi:`pytest`
A quick example
---------------
.. code-block:: python
# content of test_sample.py
def inc(x):
return x + 1
def test_answer():
assert inc(3) == 5
To execute it:
.. code-block:: pytest
$ pytest
=========================== test session starts ============================
platform linux -- Python 3.x.y, pytest-8.x.y, pluggy-1.x.y
rootdir: /home/sweet/project
collected 1 item
test_sample.py F [100%]
================================= FAILURES =================================
_______________________________ test_answer ________________________________
def test_answer():
> assert inc(3) == 5
E assert 4 == 5
E + where 4 = inc(3)
test_sample.py:6: AssertionError
========================= short test summary info ==========================
FAILED test_sample.py::test_answer - assert 4 == 5
============================ 1 failed in 0.12s =============================
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used.
See :ref:`Get started <getstarted>` for a basic introduction to using pytest.
Features
--------
- Detailed info on failing :ref:`assert statements <assert>` (no need to remember ``self.assert*`` names)
- :ref:`Auto-discovery <test discovery>` of test modules and functions
- :ref:`Modular fixtures <fixture>` for managing small or parametrized long-lived test resources
- Can run :ref:`unittest <unittest>` (including trial) test suites out of the box
- Python 3.8+ or PyPy 3
- Rich plugin architecture, with over 1300+ :ref:`external plugins <plugin-list>` and thriving community
