.. _running-tests: Running tests ============= Wand has unit tests and regression tests. It can be run using :file:`setup.py` script: .. sourcecode:: console $ python setup.py test It uses pytest_ as its testing library. The above command will automatically install pytest as well if it's not installed yet. Or you can manually install pytest and then use :program:`pytest` command. It provides more options: .. sourcecode:: console $ pip install pytest $ pytest .. _pytest: http://pytest.org/ Skipping tests -------------- There are some time-consuming tests. You can skip these tests using ``--skip-slow`` option: .. sourcecode:: console $ pytest --skip-slow Be default, tests include regression testing for the PDF format. Test cases will fail if the system does not include `Ghostscript`_ binaries. You can skip PDF dependent tests with ``--skip-pdf`` option: .. sourcecode:: console $ pytest --skip-pdf .. _Ghostscript: https://www.ghostscript.com The same behavior is true for `Fourier Transform`_ library. Use ``--skip-fft`` to skip over any discrete Fourier transformation test cases. .. sourcecode:: console $ pytest --skip-fft .. _Fourier Transform: http://www.fftw.org/ You can run only tests you want using ``-k`` option. .. sourcecode:: console $ pytest -k image The source code repository for Wand doesn't ship any `pytest.ini` configuration files. However nightly regression test are usually run in parallel with coverage reports. An example `pytest.ini` file might look like:: [pytest] addopts=-n8 -rsfEw --cov wand --cov-report html Using tox_ ---------- Wand should be compatible with various Python implementations including CPython 2.6, 2.7, PyPy. tox_ is a testing software that helps Python packages to test on various Python implementations at a time. It can be installed using :program:`pip`: .. sourcecode:: console $ pip install tox If you type just :program:`tox` at Wand directory it will be tested on multiple Python interpreters: .. sourcecode:: console $ tox GLOB sdist-make: /Users/emcconville/Desktop/wand/setup.py py26 create: /Users/emcconville/Desktop/wand/.tox/py26 py26 installdeps: pytest py26 sdist-inst: /Users/emcconville/Desktop/wand/.tox/dist/Wand-0.2.2.zip py26 runtests: commands[0] ... You can use a double ``--`` to pass options to pytest: .. sourcecode:: console $ tox -- -k sequence .. _tox: http://tox.testrun.org/ Continuous Integration ---------------------- .. image:: https://secure.travis-ci.org/emcconville/wand.svg?branch=master :alt: Build Status :target: https://travis-ci.org/emcconville/wand `Travis CI`_ automatically builds and tests every commit and pull request.
