用python编写测试脚本

 def f(n):
 """
 >>>f(1)
 1用例
 >>>f(2）
 2用例
 ......
 >>>f(n)
 n用例

 """
 print(n)
 if __name__ == "__main__"
 import doctest
 doctest.testmod()

 from widget import widget
 import unittest

 #执行测试用例的类
     class widgetTestCase(unittest.TestCase)

     def setUp(self):
         self.widget = widget()
     def tearDown(self):
         self.widget.dispose()
         self.widget = None
     def testSize(self):
         self.assertEqual(self, widget.getSize(),(40,40))
     def testResize(self):
         self.widget.resize(100,100)
         self.assertEqual(self, widget.getSize(), (100,100))
 #测试
 if __name__ = "__main__":

构造测试集

1 suit = unittest.TestSuite()
2 suit.addTest(widgetTestCase("testSize"))
3 suit.addTest(widgetTestCase("testResize"))

执行测试

1 runner = unittest.TextTestRunner()
2 runner.run(suite)

1>构造TestCase

setup和teardown负责预处理和善后工作

2>构造测试用例集，添加用例

3>执行用例说明测试方法，N多测试函数

TestCase.assert_(expr[, msg]) 
TestCase.failUnless(expr[, msg]) 
TestCase.assertTrue(expr[, msg]) 
TestCase.assertEqual(first, second[, msg]) 
TestCase.failUnlessEqual(first, second[, msg]) 
TestCase.assertNotEqual(first, second[, msg]) 
TestCase.failIfEqual(first, second[, msg]) 
TestCase.assertAlmostEqual(first, second[, places[, msg]]) 
TestCase.failUnlessAlmostEqual(first, second[, places[, msg]]) 
TestCase.assertNotAlmostEqual(first, second[, places[, msg]]) 
TestCase.failIfAlmostEqual(first, second[, places[, msg]]) 
TestCase.assertRaises(exception, callable, ...) 
TestCase.failUnlessRaises(exception, callable, ...) 
TestCase.failIf(expr[, msg]) 
TestCase.assertFalse(expr[, msg]) 
TestCase.fail([msg])
