The ``pytest`` framework makes it easy to write small tests, yet
scales to support complex functional testing for applications and libraries.
An example of a simple test:
.. code-block:: python
# content of test_sample.py
def inc(x):
return x + 1
def test_answer():
assert inc(3) == 5
To execute it::
$ pytest
============================= test session starts =============================
collected 1 items
test_sample.py F
================================== FAILURES ===================================
_________________________________ test_answer _________________________________
def test_answer():
> assert inc(3) == 5
E assert 4 == 5
E + where 4 = inc(3)
test_sample.py:5: AssertionError
========================== 1 failed in 0.04 seconds ===========================
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <https://docs.pytest.org/en/latest/getting-started.html#our-first-test-run>`_ for more examples.
Features
--------
- Detailed info on failing `assert statements <https://docs.pytest.org/en/latest/assert.html>`_ (no need to remember ``self.assert*`` names);
- `Auto-discovery
<https://docs.pytest.org/en/latest/goodpractices.html#python-test-discovery>`_
of test modules and functions;
- `Modular fixtures <https://docs.pytest.org/en/latest/fixture.html>`_ for
managing small or parametrized long-lived test resources;
- Can run `unittest <https://docs.pytest.org/en/latest/unittest.html>`_ (or trial),
`nose <https://docs.pytest.org/en/latest/nose.html>`_ test suites out of the box;
- Python 2.7, Python 3.4+, PyPy 2.3, Jython 2.5 (untested);
- Rich plugin architecture, with over 315+ `external plugins <http://plugincompat.herokuapp.com>`_ and thriving community;
