Python之PyUnit单元测试实例

本文实例讲述了Python之PyUnit单元测试，与erlang eunit单元测试很像，分享给大家供大家参考。具体方法如下：

1.widget.py文件如下：

#!/usr/bin/python

# Filename:widget.py

class Widget:

def __init__(self, size = (40, 40)):

self.size = size



def getSize(self):

return self.size



def resize(self, width, height):

if width < 0 or height < 0:

raise ValueError, "illegal size"

self.size = (width, height)



def dispose(self):

passDefaultTestCase

2. auto.py文件如下：

#!/usr/bin/python

# Filename:auto.py



import unittest

from widget import Widget



class WidgetTestCase(unittest.TestCase):

def setUp(self):

self.widget = Widget()



def tearDown(self):

self.widget = None



def testSize(self):

self.assertEqual(self.widget.getSize(), (50, 40))



def suite():

suite = unittest.TestSuite()

suite.addTest(WidgetTestCase("testSize"))

return suite



if __name__ == "__main__":

unittest.main(defaultTest = 'suite')

3.执行结果如下：

[code]jobin@jobin-desktop:~/work/python/py_unit$ python auto.py
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK
jobin@jobin-desktop:~/work/python/py_unit$ python auto.py
F
======================================================================
FAIL: testSize (__main__.WidgetTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
File "auto.py", line 15, in testSize
self.assertEqual(self.widget.getSize(), (50, 40))
AssertionError: (40, 40) != (50, 40)

----------------------------------------------------------------------
Ran 1 test in 0.000s

FAILED (failures=1)
jobin@jobin-desktop:~/work/python/py_unit$[/code]

希望本文所述对大家的Python程序设计有所帮助。
