.. _features: pytest: helps you write better programs ============================================= .. note:: Upcoming: `professional testing with pytest and tox <http://www.python-academy.com/courses/specialtopics/python_course_testing.html>`_ , 24th-26th June 2013, Leipzig. **a mature full-featured Python testing tool** - runs on Posix/Windows, Python 2.4-3.3, PyPy and Jython-2.5.1 - :ref:`comprehensive online <toc>` and `PDF documentation <pytest.pdf>`_ - used in :ref:`many projects and organisations <projects>`, in test suites ranging from 10 to 10s of thousands of tests - comes with many :ref:`tested examples <examples>` **provides easy no-boilerplate testing** - makes it :ref:`easy to get started <getstarted>`, many :ref:`usage options <usage>` - :ref:`assert with the assert statement` - helpful :ref:`traceback and failing assertion reporting <tbreportdemo>` - allows :ref:`print debugging <printdebugging>` and :ref:`the capturing of standard output during test execution <captures>` **scales from simple unit to complex functional testing** - (new in 2.3) :ref:`modular parametrizeable fixtures <fixture>` - :ref:`parametrized test functions <parametrized test functions>` - :ref:`mark` - :ref:`skipping` - can :ref:`distribute tests to multiple CPUs <xdistcpu>` through :ref:`xdist plugin <xdist>` - can :ref:`continuously re-run failing tests <looponfailing>` - many :ref:`builtin helpers <pytest helpers>` and :ref:`plugins <plugins>` - flexible :ref:`Python test discovery` **integrates many common testing methods**: - multi-paradigm: pytest can run many ``nose``, ``unittest.py`` and ``doctest.py`` style test suites, including running testcases made for Django and trial - supports :ref:`good integration practises <goodpractises>` - supports extended :ref:`xUnit style setup <xunitsetup>` - supports domain-specific :ref:`non-python tests` - supports the generation of testing coverage reports - `Javascript unit- and functional testing`_ - supports :pep:`8` compliant coding styles in tests **extensive plugin and customization system**: - all collection, reporting, running aspects are delegated to hook functions - customizations can be per-directory, per-project or per PyPI released plugins - it is easy to add command line options or do other kind of add-ons and customizations. .. _`Javascript unit- and functional testing`: http://pypi.python.org/pypi/oejskit .. _`easy`: http://bruynooghe.blogspot.com/2009/12/skipping-slow-test-by-default-in-pytest.html
