Wand has unit tests and regression tests. It can be run using
$ 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 pytest command. It provides more options:
$ pip install pytest $ pytest
There are some time-consuming tests. You can skip these tests using
$ 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
$ pytest --skip-pdf
The same behavior is true for Fourier Transform library. Use
to skip over any discrete Fourier transformation test cases.
$ pytest --skip-fft
You can run only tests you want using
$ 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
Wand should be compatible with various Python implementations including CPython 2.7, 3.3, 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 ...
You can use a double
-- to pass options to pytest:
$ tox -- -k sequence
