Python单元测试框架unittest测试过程简介1. 2. 编写测试的类继承unittest.class Teste

测试步骤\

1. 导入unittest模块

import unittest

2. 编写测试的类继承unittest.TestCase

class Tester(unittest.TestCase)

3. 编写测试的方法必须以test开头

def test_add(self)

def test_sub(self)

4.使用``TestCase class提供的方法测试功能点

Method	Checks that	New in
`assertEqual(a,b)`	`a==b`
`assertNotEqual(a,b)`	`a!=b`
`assertTrue(x)`	`bool(x)isTrue`
`assertFalse(x)`	`bool(x)isFalse`
`assertIs(a,b)`	`aisb`	2.7
`assertIsNot(a,b)`	`aisnotb`	2.7
`assertIsNone(x)`	`xisNone`	2.7
`assertIsNotNone(x)`	`xisnotNone`	2.7
`assertIn(a,b)`	`ainb`	2.7
`assertNotIn(a,b)`	`anotinb`	2.7
`assertIsInstance(a,b)`	`isinstance(a,b)`	2.7
`assertNotIsInstance(a,b)`	`notisinstance(a,b)`	2.7

5.调用unittest.main()方法运行所有以test开头的方法

if __name__ == '__main__':
unittest.main()\

实例如下

被测试类

#!/usr/bin/python
#coding=utf-8

class Computer(object):
	@staticmethod
	def add(a, b):
		return a + b;
	
	@staticmethod
	def sub(a, b):
		return a - b;<strong>	</strong>

**
**

测试类

#!/usr/bin/python
#coding=utf-8
import unittest
from Testee import Computer

class Tester(unittest.TestCase):	
	def test_add(self):
		self.assertEqual(Computer.add(2, 3), 5, "test add function")
		
	def test_sub(self):
		self.assertEqual(Computer.sub(5, 1), 4, "test sub function")	

if __name__ == '__main__':
		unittest.main()

运行结果:
