python nose框架_python自动化框架nose

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

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 in0.000s

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 in0.044s

OK

nose的执行规则：

和unittest一样，会优先执行setUp，最后执行tearDown，和函数的位置没关系

deftearDown():

print "teardown"

deftest1():

print 1

#assert(1==2)

deftest2():

print 2

defsetUp():

print "this setup"C:\Users\Administrator>nosetests -s -v "d:\\00"this setup

testnose.test1 ... 1ok

testnose.test2 ... 2ok

teardown

=

------------------------------------------------Ran 2tests in0.010s

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
