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
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)
]

希望本文所述对大家的python程序设计有所帮助。
