python unittest的简单使用

一.首先创建两个测试类

test1.py:

#!/user/bin/env python

#-*- coding: utf-8 -*-

import os

import unittest

class test1(unittest.TestCase):

def setUp(self):

print "this test1 setup()"

def tearDown(self):

print "this test1 tearDown()"

def testcase1(self):

print "testcase1-1"

def testcase2(self):

print "testcase1-2"

test2.py:

#!/user/bin/env python

#-*- coding: utf-8 -*-

import os

import unittest

class test2(unittest.TestCase):

def setUp(self):

print "this test2 setup()"

def tearDown(self):

print "this test2 tearDown()"

def testcase1(self):

print "testcase2-1"

def testcase2(self):

print "testcase2-2"

unittest框架的使用：1.import unittest 2.测试类继承unittest.TestCase 3.每个测试类都有setUp()和tearDown() 可用于测试用例的初始化和最终操作，测试类里的每个测试用例都会执行setUp()和tearDown() 3.测试用例方法的名称必须以test开头

二.测试用例组织和运行：（在此介绍三种执行测试用例的方式）

#!/user/bin/env python

#-*- coding: utf-8 -*-

import os

import unittest

from test1 import test1

from test2 import test2

if __name__ == '__main__':

#第一种方法

#构造测试集，逐个添加测试用例方法

suite = unittest.TestSuite()

suite.addTest(test1.testcase1())

suite.addTest(test2.testcase2())

#执行测试套件

runner = unittest.TextTestRunner()

runner.run(suite)

#第二种方法，符合正则表达式的测试类里的所有测试用例

# discover = unittest.defaultTestLoader.discover("./", pattern="my*.py")

# runner = unittest.TextTestRunner

# runner.run(discover)

# #第三种方法：运行当前测试文件下的所有测试用例

# unittest.main()

执行结果：

Finding files...

['E:\\Work\\Python\\Python_Study\\src\\mytest.py'] ... done

Importing test modules ... done.

testcase1 (test1.test1) ... this test1 setup()

testcase1-1

this test1 tearDown()

ok

testcase2 (test1.test1) ... this test1 setup()

testcase1-2

this test1 tearDown()

ok

testcase1 (test2.test2) ... this test2 setup()

testcase2-1

this test2 tearDown()

ok

testcase2 (test2.test2) ... this test2 setup()

testcase2-2

this test2 tearDown()

ok
