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;
