对所有鼻子测试进行一次设置和拆卸功能 [英] Setup and teardown functions executed once for all nosetests tests

问题描述

如何对所有的鼻子测试进行一次设置和拆卸功能?

How to execute setup and teardown functions once for all nosetests tests?

def common_setup():
    #time consuming code
    pass

def common_teardown():
    #tidy up
    pass

def test_1():
    pass

def test_2():
    pass

#desired behavior
common_setup()
test_1()
test_2()
common_teardown()

请注意，存在一个

Note that there exists a similar question with an answer that is not working with python 2.7.9-1, python-unittest2 0.5.1-1 and python-nose 1.3.6-1 after replacing the dots with pass and adding the line import unittest. Unfortunately my reputation is too low to comment on that.

推荐答案

您可以具有模块级设置功能.根据鼻子文档:

You can have a module level setup function. According to nose documentation:

测试模块提供模块级别的设置和拆卸；定义方法 设置， setup_module ，setUp或setUpModule进行设置，拆卸， teardown_module ，或使用tearDownModule进行拆卸.

Test modules offer module-level setup and teardown; define the method setup, setup_module, setUp or setUpModule for setup, teardown, teardown_module, or tearDownModule for teardown.

因此，更具体地说，针对您的情况:

So, more specifically, for your case:

def setup_module():
    print "common_setup"

def teardown_module():
    print "common_teardown"

def test_1():
    print "test_1"

def test_2():
    print "test_2"

运行测试为您提供:

$ nosetests common_setup_test.py -s -v
common_setup
common_setup_test.test_1 ... test_1
ok
common_setup_test.test_2 ... test_2
ok
common_teardown

----------------------------------------------------------------------
Ran 2 tests in 0.000s

OK

选择哪个名称都没有关系，因此setup和setup_module的工作原理相同，但是setup_module更加清晰.

It does not matter which name you choose, so both setup and setup_module would work the same, but setup_module has more clarity to it.
