nose的使用

简单的例子：

test1,简单的能够运行

temperature1.py

def to_celsius (t):  
    return round ( (t-32.0)*5.0/9.0 )  
  
def above_freezing (t):  
    return t>0  

 

test_temperature.py

import nose
from python2.temperature1  import *

def test_above_freezing ():  
    '''''Test above_freezing '''  
    assert above_freezing(89.4), 'A temperature above freezing'  
    assert not above_freezing(-42), 'A temperature below freezing'  
    assert not above_freezing(0), 'A temperature at freezing'  
  
def test_boiling ():  
    '''''Test boiling point'''  
    assert to_celsius(212) == 100  
  
def test_roundoff ():  
    '''''Test that roundoff works'''  
    assert to_celsius(100) == 38, 'Returning an unrounded result'   #not 37.77...  
  
if __name__ == "__main__":  
    nose.runmodule()
   # nose.main()  两种方式运行

命令行运行：nosetests -v -s nose_test3.py

test2，默认会运行setup和teardown

通过修饰器：

from nose.tools.nontrivial import with_setup
def setup_func():
    print("set up test fixtures")

def teardown_func():
    print("tear down test fixtures")

@with_setup(setup_func, teardown_func)
def test():
    "test ..."

结果：
