+The ``pytest`` framework makes it easy to write small tests, yet
+scales to support complex functional testing for applications and libraries.    
 
-Changelog: http://pytest.org/latest/changelog.html
+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::
+
+    $ py.test
+    ======= 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 ``py.test``'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.

-A simple example for a test:
-
-.. code-block:: python
-
-    # content of test_module.py
-    def test_function():
-        i = 4
-        assert i == 3
-
-which can be run with ``py.test test_module.py``.  See `getting-started <http://pytest.org/latest/getting-started.html#our-first-test-run>`_ for more examples.
