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])
