classic xunit-style setup
|
|
========================================
|
|
|
|
.. note::
|
|
|
|
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:`fixture functions
|
|
<fixture>` or :ref:`funcargs <resources>` for implementing your
|
|
needs to prepare and fix the test state for your tests.
|
|
|
|
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.
