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：

代码如下:

#!/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：

代码如下:

#!/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。
