# Running tests¶

Wand has unit tests and regression tests. It can be run using setup.py script:

$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 py.test command. It provides more options: $ pip install pytest
$py.test  ## Skipping tests¶ There are some time-consuming tests. You can skip these tests using --skip-slow option: $ py.test --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:

$py.test --skip-pdf  You can run only tests you want using -k option. $ py.test -k image


## 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 pip:

$pip install tox  If you type just tox at Wand directory it will be tested on multiple Python interpreters: $ 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:

\$ tox -- -k sequence
