Requirements for testing¶
NetworkX uses the Python nose testing package. If you don’t already have that package installed, follow the directions on the nose homepage.
Testing a source distribution¶
You can test the complete package from the unpacked source directory with:
python setup_egg.py nosetests
Testing an installed package¶
If you have a file-based (not a Python egg) installation you can test the installed package with
>>> import networkx >>> networkx.test()
python -c "import networkx; networkx.test()"
Testing for developers¶
You can test any or all of NetworkX by using the “nosetests” test runner.
First make sure the NetworkX version you want to test is in your PYTHONPATH (either installed or pointing to your unpacked source directory).
Then you can run individual test files with:
or all tests found in dir and an directories contained in dir:
By default nosetests doesn’t test docutils style tests in Python modules but you can turn that on with:
For doctests in stand-alone files NetworkX uses the extension txt so you can add:
nosetests --with-doctest --doctest-extension=txt
to also execute those tests.
These options are on by default if you run nosetests from the root of the NetworkX distribution since they are specified in the setup.cfg file found there.
