一、直接使用TestCase
注意所有测试方法都需要以test开头。代码如下：
import unittest class Test1(unittest.TestCase):
@classmethod
def setUpClass(self):
print("execute setUpClass") @classmethod
def tearDownClass(self):
print("execute tearDownClass") def setUp(self):
print("execute setUp") def tearDown(self):
print("execute tearDown") def test_one(self):
print('execute test_one')
self.assertTrue('FOO'.isupper()) def test_two(self):
print('execute test_two') if __name__ == '__main__':
unittest.main()
执行如下：
二、使用TestSuite
直接写TestCase执行时是按字母排序的顺序执行的，如果要设定测试用例的执行先后顺序则需要将TestCase封装到TestSuite。代码如下：
import unittest class Test2(unittest.TestCase):
@classmethod
def setUpClass(self):
print("execute setUpClass") @classmethod
def tearDownClass(self):
print("execute tearDownClass") def setUp(self):
print("execute setUp") def tearDown(self):
print("execute tearDown") def test_one(self):
print('execute test_one')
self.assertTrue('FOO'.isupper()) def test_two(self):
print('execute test_two') if __name__ == '__main__':
suite = unittest.TestSuite()
# Test2是要测试的类名，test_two是要执行的测试方法
suite.addTest(Test2("test_two"))
suite.addTest(Test2("test_one"))
runner = unittest.TextTestRunner()
runner.run(suite)
执行如下，可以看到先添加的test_two先执行：
三、使用HTMLTestRunner
我们可能还会希望生成一个简单的HTML报告，可使用HTMLTestRunner实现。但pypi和官网上最新的都是只支持python2.x的0.8.2版本。可将以下代码自行保存成HTMLTestRunner.py放到自己项目目录下
# -*- coding: utf-8 -*-
"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance. The simplest way to use this is to invoke its main method. E.g. import unittest
import HTMLTestRunner ... define your tests ... if __name__ == '__main__':
HTMLTestRunner.main() For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g. # output to a file
fp = file('my_report.html', 'wb')
runner = HTMLTestRunner.HTMLTestRunner(
stream=fp,
title='My unit test',
description='This demonstrates the report output by HTMLTestRunner.'
) # Use an external stylesheet.
# See the Template_mixin class for more customizable options
runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">' # run the test
runner.run(my_test_suite) ------------------------------------------------------------------------

四、HTMLTestRunner未生成报告问题处理
4.1 pytest干扰
如果python环境中安装了pytest，那么默认运行时会是Run 'py.test for'（如下图所示），这时if __name__ == "__main__"下的语句是不被执行的所以报告肯定不会生成（原理未知）。
些时需要依次点开pycharm菜单----Run----Edit Configurations...自行添加一个运行配置，如下图
4.2 路径问题
一是注意自己把报告输出到了哪个位置，特别是如果有几个地方都会输出报告时不要弄混了，搞得自己在浏览器中刷新半天没看到有变化，认为没生成报告。
二是实践中通过os.getcwd()发现python运行时的目录不一定是当前目录，所以如果报告使用相对路径然后又没看到有报告生成，那就注意看os.getcwd()返回的运行路径是不是当前文件夹。
