为什么python+htmltestrunner生成的测试报告有问题

htmltestrunner 默认要2条以上的用例才不会生成空的测试报告，你再多加一条，每条测试用例以test开头，再后面标注01/02/03........ 比如：test_baidu_login_01 这样就会生存测试报告了

问题：一个百度首页搜索的一个python+unittest测试，代码执行成功，但是用HTMLTestRunner输出的测试报告里面得内容有问题，具体问题是：测试条数，成功数，失败数都为0

if __name__=="__main__":
test=unittest.TestSuite()

test.addTest(setUp)
test.addTest(test_baidu)

file_path="D:\\workspace\\PythonLearn\\src\\LoginBaiDu\\result.html"
file_result=open(file_path,'wb')

runner=HTMLTestRunner.HTMLTestRunner(stream=file_result,title=u"百度首页测试",description=u"用例执行情况")

runner.run(test)
file_result.close()

生成的报告截图：

加测试用例的方式错了要
test=unittest.TestSuite()
test.addTest(LoginBaiDu('setUp'))
test.addTest(LoginBaiDu('test_baidu'))
或者直接加入类
test= unittest.TestLoader().loadTestsFromTestCase(LoginBaiDu)
