一、配置：
HTMLTestRunner看了源码才知道作者是：Wai Yip Tung.到底这是哪位大神就不做深究了，至少我很敬佩。
1、下载HTMLTestRunner.py文件：地址
http://tungwaiyip.info/software/HTMLTestRunner.html
2、将该文件保存在python安装路径下的lib文件夹中。在文件中能import HTMLTestRunner成功，即配置成功。
注：如果失败，在项目中新建一个这样的文件也是可以的，只要达到能引入和使用就行。
二、使用
引入完成后，在调用测试文件中加入如下代码即可：
if __name__ == '__main__':
testunit=unittest.TestSuite() #定义一个单元测试容器
testunit.addTest(element("test_find_element")) #将测试用例加入到测试容器中
testunit.addTest(element("test_search"))
filename="./xxx.html" #定义个报告存放路径，支持相对路径。
fp=file(filename,'wb')
runner = HTMLTestRunner.HTMLTestRunner(stream=fp,title='Report_title',description='Report_description') #使用HTMLTestRunner配置参数，输出报告路径、报告标题、描述
runner.run(
testunit) #自动进行测试
生成报告如下：
element：单元测试类名
test_find_element：测试用例方法名
详细信息：测试用例方法中print的数据、出错后信息。
附上单元测试里的一些方法：
常用方法：
assertEqual(a, b) a == b
assertNotEqual(a, b) a != b
assertTrue(x) bool(x) is True
assertFalse(x) bool(x) is False
assertIs(a, b) a is b #python 2.7
assertIsNot(a, b) a is not b #python 2.7
assertIsNone(x) x is None #python 2.7
assertIsNotNone(x) x is not None #python 2.7
assertIn(a, b) a in b #python 2.7
assertNotIn(a, b) a not in b #python 2.7
assertIsInstance(a, b) isinstance(a, b) #python 2.7
assertNotIsInstance(a, b) not isinstance(a, b) #python 2.7
assertEqual(a, b) a == b
assertNotEqual(a, b) a != b
assertTrue(x) bool(x) is True
assertFalse(x) bool(x) is False
assertIs(a, b) a is b #python 2.7
assertIsNot(a, b) a is not b #python 2.7
assertIsNone(x) x is None #python 2.7
assertIsNotNone(x) x is not None #python 2.7
assertIn(a, b) a in b #python 2.7
assertNotIn(a, b) a not in b #python 2.7
assertIsInstance(a, b) isinstance(a, b) #python 2.7
assertNotIsInstance(a, b) not isinstance(a, b) #python 2.7
用于执行更具体的检查，如：
Method Checks that New in
assertAlmostEqual(a, b) round(a-b, 7) == 0
assertNotAlmostEqual(a, b) round(a-b, 7) != 0
assertGreater(a, b) a > b #python 2.7
assertGreaterEqual(a, b) a >= b #python 2.7
assertLess(a, b) a < b #python 2.7
assertLessEqual(a, b) a <= b #python 2.7
assertRegexpMatches(s, re) regex.search(s) #python 2.7
assertNotRegexpMatches(s, re) not regex.search(s) #python 2.7
assertItemsEqual(a, b) sorted(a) == sorted(b) and works with unhashable objs #python 2.7
assertDictContainsSubset(a, b) all the key/value pairs in a exist in b #python 2.7
assertMultiLineEqual(a, b) strings #python 2.7
assertSequenceEqual(a, b) sequences #python 2.7
assertListEqual(a, b) lists #python 2.7
assertTupleEqual(a, b) tuples #python 2.7
assertSetEqual(a, b) sets or frozensets #python 2.7
assertDictEqual(a, b) dicts #python 2.7
assertMultiLineEqual(a, b) strings #python 2.7
assertSequenceEqual(a, b) sequences #python 2.7
assertListEqual(a, b) lists #python 2.7
