1. 单个测试集

# coding:utf-8
import json, os, sys, unittest,HTMLTestRunner,requests

reload(sys)
sys.setdefaultencoding('utf8')
class ServiceTest(unittest.TestCase):

    def setUp(self):
        self.url ='www.baidu.com'

    def test_get_service_list(self):
        data={}
        r=requests.get('http://www.cnblogs.com/xiyozhang136/p/7427730.html')

    def tearDown(self):
        pass

if __name__ =='__main__':
    testsuite = unittest.TestSuite()
    testsuite.addTest(ServiceTest("test_get_service_list"))
    runner = unittest.TextTestRunner()
    fp = file('ttt.html', 'wb')
    #可以用print
    runner.run = unittest.TextTestRunner(verbosity=2).run(testsuite)
    #输出测试报告
    # runner = HTMLTestRunner.HTMLTestRunner(
    #     stream=fp,
    #     title=u'接口测试报告',
    #     description=u'用例执行情况：')

    # fp = open('res.html','wb')#打开一个保存结果的html文件
    # runner = HTMLTestRunner.HTMLTestRunner(stream=fp,title='api测试报告',description='测试情况')
    # runner.run(testsuite)

这里选择unittest.TextTestRunner(verbosity=2).run(testsuite)则控制台可以显示print出来的内容，如果选择HTMLTestRunner则控制台不输出，在测试报告中输出内容

1. 运行多个测试集
   
   目录结构如下：
   
   

test1内容如下

#coding:utf-8
import unittest
import time

class Test(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print("开始测试1")
    @classmethod
    def tearDownClass(cls):
         print("结束测试")
    def setUp(self):
         print("开始单个测试用例")
    def tearDown(self):
         print("结束单个测试用例")


    def test01(self):
        '''测试0201'''
        print("执行测试用例1")
    def test02(self):
        '''测试0202'''
        print("执行测试用例01")

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

test2内容如下

#coding:utf-8
import unittest
import time

class Test(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print("开始测试2")
    def tearDown(self):
        print("测试结束2")
    def test01(self):
        '''测试0201'''
        print("执行测试用例2")
    def test02(self):
        '''测试0202'''
        print("执行测试用例02")

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

• setUpClass一个测试集的开始运行
• tearDownClass一个测试集的结束运行
• setUp开始单个测试用例运行
• tearDown结束单个测试用例运行

运行all_test如下

#coding:utf-8
import unittest
import os,sys
import HTMLTestRunner
#from send_email import main2
#待执行用例的目录
reload(sys)
sys.setdefaultencoding('utf8')
def allcase():
    #写路径即可
    case_dir="/test"
    #case_path=os.path.join(os.getcwd(),"case")
    testcase=unittest.TestSuite()
    discover=unittest.defaultTestLoader.discover(case_dir,
                                                 pattern='test*.py',
                                                 top_level_dir=None)
    #discover方法筛选出来的用例，循环添加到测试套件中
    #print(discover)
    for test_suite in discover:
        for test_case in test_suite:
            #添加用例到testcase
            print(test_case)
            testcase.addTest(test_case)
    return testcase
if __name__=="__main__":
    runner=unittest.TextTestRunner()
    runner.run(allcase())
    report_path="test.html"
    fp=open(report_path,"wb")
    runner=HTMLTestRunner.HTMLTestRunner(stream=fp,
                                         title="自动化测试unittest测试框架报告",
                                         description="用例执行情况：")

    runner.run(allcase())
    fp.close()
