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
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 easy_install or pip:
$ easy_install tox
If you type just tox at Wand directory it will be tested on multiple Python interpreters:
$ tox
GLOB sdist-make: /Users/dahlia/Desktop/wand/setup.py
py26 create: /Users/dahlia/Desktop/wand/.tox/py26
py26 installdeps: pytest
py26 sdist-inst: /Users/dahlia/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
