 pytest will automatically collect ``unittest.TestCase`` subclasses and
 their ``test`` methods in ``test_*.py`` or ``*_test.py`` files.
 
-Almost all ``unittest`` features are supported, like ``@unittest.skip`` style decorators, ``setUp/tearDown``,
-``setUpClass/tearDownClass()``, etc (see :ref:`unittest-limitations`).

-Benefits
---------
-
-You can make use of several pytest features, most without changing any existing code:
-
-* Use :ref:`plain assert-statements <assert>` instead of ``self.assert*`` functions (`unittest2pytest
-  <https://pypi.python.org/pypi/unittest2pytest/>`__ is immensely helpful in this);
-* Obtain :ref:`more informative tracebacks <tbreportdemo>`;
-* :ref:`stdout and stderr <captures>` capturing;
-* :ref:`Test selection options <select-tests>` using ``-k`` and ``-m`` flags;
-* :ref:`maxfail`;
-* :ref:`--pdb <pdb-option>` command-line option for debugging on test failures
-  (see :ref:`note <pdb-unittest-note>` below);
-* Distribute tests to multiple CPUs using the `pytest-xdist <http://pypi.python.org/pypi/pytest-xdist>`_ plugin;
