python除了unittest，還有一款更快捷的nose，nose可以說是對unittest的一種簡化吧
但是他不需要unittest那種必須有固有的格式，他只需要文件，類名，方法名等含有test就可以
unittest是需要手動來寫discover函數來遍歷用例的
- Name my test modules/files starting with ‘test_’.
- Name my test functions starting with ‘test_’.
- Name my test classes starting with ‘Test’.
- Name my test methods starting with ‘test_’.
- Make sure all packages with test code have an ‘init.py’ file.

里面介紹的很詳細，一下總結幾個常用的點：
安裝：
easy_install nose
運行：
nosetests [文件]
nosetests [目錄]
如果不加目錄，默認執行當前目錄下的所有符合nose條件的用例，
如果加目錄，則運行指定目錄里面符合nose條件的用例
常用參數
-v 把運行中的具體過程輸出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 把測試用例中的print輸出打印到控制台，這個調試的時候還是挺方便的
C:\Users\Administrator>nosetests -s "d:\\00" thisisprint1 .thisisprint2 ------------------------------------------------ Ran 2 tests in 0.044s OK
nose的執行規則：
和unittest一樣，會優先執行setUp，最后執行tearDown，和函數的位置沒關系
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數，比如類似unittest的assertEqual
使用方法
from nose import tools
