4. Testing with tox¶
Tox uses py.test under the hood, hence it supports the same syntax for selecting tests.
For further information please consult the pytest usage docs.
To run a particular test class with tox:
$ tox -e py '-k TestFindHooks'
To run some tests with names matching a string expression:
$ tox -e py '-k generate'
Will run all tests matching “generate”, test_generate_files for example.
To run just one method:
$ tox -e py '-k "TestFindHooks and test_find_hook"'
To run all tests using various versions of python in virtualenvs defined in tox.ini, just run tox.:
$ tox
This configuration file setup the pytest-cov plugin and it is an additional dependency. It generate a coverage report after the tests.
It is possible to tests with some versions of python, to do this the command is:
$ tox -e py27,py34,pypy
Will run py.test with the python2.7, python3.4 and pypy interpreters, for example.
