公司需要设计一个稳定性测试，就是一直持续的跑不同的用例，直到人为停止，用例基本完成，基本框架思路就是随机选择一个testcase，跑完后输出结果。但存在一个问题，现在的unittest或nose测试报告都是测完所有case后再输出html报告，再次运行，又生成新的，没法再原来的报告中再填加结果。
就这样问题，基本解决思路就是直接写个生成html报告的模块，然后再次每次结果加入。正好最近在看tempest的东西，里面有个这样的模块，那就不重复造轮子了，直接拿过来用吧。
先看看生成html_log.py文件

空模板见下面的html代码，copy下来后存成html文件即可使用
Unit Test Report Overview
Class Fail Error Skip Success Total Total 0 0 0 0 0 Failure details
Failure details
All tests
all tests
使用unittest写个示范代码如下：
import unittestimport timeimport sysimport html_logimport osimport reimport randomclass test(unittest.TestCase): def setUp(self): pass def test_0001(self): assert 1==1 def test_0002(self): assert 2==2if __name__=='__main__': suite=unittest.TestLoader().loadTestsFromTestCase(test) testcases=list() listcasedir='.' testunit=unittest.TestSuite() #选择case for test_case in suite: print test_case f=re.match("(test_.*) \(__main__.test\)",str(test_case)) tt=f.group(1) testcases.append(test_case) test = random.choice(testcases) mySuite = unittest.TestSuite() mySuite.addTest(test) result = unittest.TextTestRunner().run(mySuite) #这里xx.html就是对应的空模板 if not os.path.exists('test_aa.html'): html_log.create_log_from_file('test_aa.html', 'xx.html') #将结果持续加入到对应的html报告中 print test html_log.add_testrunner_log('test_aa.html', result, test) 结果如下，测试一直在进行，结果就一直会持续输入
