Test running ============ Direct testing using tox_ ------------------------- If you are on a Linux system run all tests with tox_. This tool automatically creates virtualenvs (see virtualenv_), installs all packages required by the test suite, and runs the tests. Run all pyudev tests against Python 2.7, Python 3.2 and PyPy:: tox -e py27,py32,pypy Pass any arguments you want to :program:`py.test` after two dashes ``--``:: tox -e py27,py32,pypy -- --enable-privileged Notes ----- Device samples ~~~~~~~~~~~~~~ Many pyudev tests run against the real device database of the system the tests are executed on. As testing against the whole database takes a long time, tests are run against a random sample by default. With the command line options provided by :mod:`~tests.plugins.udev_database` you can configure the size of this sample, or run the tests against a single device or the whole database. Privileged tests ~~~~~~~~~~~~~~~~ Some tests need to execute privileged operations like loading or unloading of kernel modules to trigger real udev events. These tests are disabled by default. Refer to :mod:`~tests.plugins.privileged` for more information on how to enable these tests and configure them properly.
