.. _`old-style xunit`:
Old-style xunit-style setup
========================================
This section describes the old way how you can implement setup and
teardown on a per-module/class/function basis. It remains fully
supported but it is recommended to rather use :ref:`@setup functions <setup>`
or :ref:`injected resources <resources>` for implementing your setup needs.
Module level setup/teardown
--------------------------------------
If you have multiple test functions and test classes in a single
module you can optionally implement the following fixture methods
which will usually be called once for all the functions::
def setup_module(module):
""" setup any state specific to the execution of the given module."""
def teardown_module(module):
""" teardown any state that was previously setup with a setup_module
method.
"""
Class level setup/teardown
----------------------------------
Similarly, the following methods are called at class level before
and after all test methods of the class are called::
@classmethod
def setup_class(cls):
""" setup any state specific to the execution of the given class (which
usually contains tests).
"""
@classmethod
def teardown_class(cls):
""" teardown any state that was previously setup with a call to
setup_class.
"""
Method and function level setup/teardown
-----------------------------------------------
Similarly, the following methods are called around each method invocation::
def setup_method(self, method):
""" setup any state tied to the execution of the given method in a
class. setup_method is invoked for every test method of a class.
"""
def teardown_method(self, method):
""" teardown any state that was previously setup with a setup_method
call.
"""
If you would rather define test functions directly at module level
you can also use the following functions to implement fixtures::
def setup_function(function):
""" setup any state tied to the execution of the given function.
Invoked for every test function in the module.
"""
def teardown_function(function):
""" teardown any state that was previously setup with a setup_function
call.
"""
Note that it is possible for setup/teardown pairs to be invoked multiple times
per testing process.
