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 func(x):
        return x + 1

    def test_answer():
        assert func(3) == 5


To execute it::

    $ pytest
    ======= test session starts ========
    platform linux -- Python 3.4.3, pytest-2.8.5, py-1.4.31, pluggy-0.3.1    
    collected 1 items

    test_sample.py F

    ======= FAILURES ========
    _______ test_answer ________

        def test_answer():
    >       assert func(3) == 5
    E       assert 4 == 5
    E        +  where 4 = func(3)

    test_sample.py:5: AssertionError
    ======= 1 failed in 0.12 seconds ========

Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <http://pytest.org/latest/getting-started.html#our-first-test-run>`_ for more examples.
        

Features
--------

- Detailed info on failing `assert statements <http://pytest.org/latest/assert.html>`_ (no need to remember ``self.assert*`` names);

- `Auto-discovery
  <http://pytest.org/latest/goodpractices.html#python-test-discovery>`_
  of test modules and functions;

- `Modular fixtures <http://pytest.org/latest/fixture.html>`_  for
