python除了unittest,还有一款更快捷的nose,nose可以说是对unittest的一种简化吧
但是他不需要unittest那种必须有固有的格式,他只需要文件,类名,方法名等含有test就可以
unittest是需要手动来写discover函数来遍历用例的
官网地址http://pythontesting.net/framework/nose/nose-introduction/
里面介绍的很详细,一下总结几个常用的点:
安装:
easy_install nose
运行:
nosetests [文件]
nosetests [目录]
如果不加目录,默认执行当前目录下的所有符合nose条件的用例,
如果加目录,则运行指定目录里面符合nose条件的用例
常用参数
-v 把运行中的具体过程输出nosetests -v
simple_example.test_um_nose.test_numbers_3_4 ... ok simple_example.test_um_nose.test_strings_a_3 ... ok ---------------------------------------------------------------------- Ran 2 tests in 0.000s OK
-s 把测试用例中的print输出打印到控制台,这个调试的时候还是挺方便的
C:\Users\Administrator>nosetests -s "d:\\00" thisisprint1 .thisisprint2 ------------------------------------------------ Ran 2 tests in 0.044s OK
nose的执行规则:
和unittest一样,会优先执行setUP,最后执行tesrDown,和函数的位置没关系
def tearDown(): print "teardown" def test1(): print 1 #assert(1==2) def test2(): print 2 def setUp(): print "this setup" C:\Users\Administrator>nosetests -s -v "d:\\00" this setup testnose.test1 ... 1 ok testnose.test2 ... 2 ok teardown = ------------------------------------------------ Ran 2tests in 0.010s OK
nose里面常用的工具有很多函数,比如类似unittest的assertEqual
使用方法
from nose import tools
