Python's pyunit Unit test example

This example describes the Python pyunit unit test, which is similar to the Erlang eunit unit test, and shares it for everyone's reference. Here's how:

The 1.widget.py file is as follows:

Copy the Code code as follows:

#!/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 files are as follows:

Copy the Code code as follows:

#!/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. The results of the implementation are as follows:

[code]jobin@jobin-desktop:~/work/python/py_unit$ python auto.py
.

Hopefully this article will help you with Python programming.
