An example of a PyUnit unit test in Python

This article illustrates PyUnit unit testing in Python, similar to Erlang eunit unit testing, for your reference. Specific methods are as follows:

1. Widget.py file is 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 file is 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 implementation results are as follows:
