1.最基本的错误截图要能提供吧。2.要是能提供出错页加载的接口信息该多好！（这个是我正在思考的问题）
3.如果可以的话，在自动化录制过程中，能全程录制，这样也利于跟踪bug（这个应该比较容易实现，毕业屏幕录制软件不少，可能需要一个脚本动态启动他们，结束关闭他们。）
在这里我顺便扯一句，可能有的公司认为自动化测试没什么价值，原因：自动化测试根本发现不了什么太多的bug。但是，我的想法是：
一、自动化测试核心不是发现多少bug，而是能确保你的项目主流程么有bug，能正常上线!如果自动化都能发现N个bug，手动人员都不需要测试的了！
二、.理论上讲自动化能覆盖所有手动测试的流程，但是你给自动化投入了多少，靠1到2个人？还更不上迭代的进度！
三、对于我们自动化人员自身而言，也要提高自己，你的价值一定不是只写写脚本，比如搭建环境的能力，搭建web框架的能力，开发桌面应用程序的能力，这些东西都能给手动测试提供便利，也是你的存在感最直接的体现！
回到正题吧，下面讲讲我的思路吧，我的想法如下：
1.因为测试的是流程，前面的test有问题后面的test我要跳过，执行也没有意思，但是报告中要体现！
2.如果出错我要能提供准确的截图。
3.我改写的unnitest要尽量方便，不要在写case上搞一堆的try....except,既不美观，也一直在写相同的代码。根据代码重构的思想，如果你一直在复制黏贴代码，你的代码一定是可以重构的！
我这里继承了unnitest.TestCase类，上篇随便我说过，unnitest就是TestCase的run方法与TestResult的游戏，那么我们就这样想，在执行run的时候如果判断为AssertError或者WebDriverException我们认为是fail，fail就自动截图(前提能拿到webdriver实例)；如果是其他的错误我们认为是error。注意fail和error是不同的 ，fail一般是bug(除非你不小心写错代码，导致控件找不到)，error是除了以上2中异常的错误，多半是运行错误不太可能是bug。多半是你自己的代码写法有问题。贴出代码如下：
#coding=utf-8
import unittest
import sys
from selenium.common import exceptions
from selenium import webdriver
class SkipTest(Exception):
"""
Raise this exception in a test to skip it.
Usually you can use TestCase.skipTest() or one of the skipping decorators
instead of raising this directly.
"""
pass
class _ExpectedFailure(Exception):
"""
Raise this when a test is expected to fail.
This is an implementation detail.
"""
def __init__(self, exc_info):
super(_ExpectedFailure, self).__init__()
self.exc_info = exc_info
class IqunxingTest(unittest.TestCase):
__screenshot_path ="C:\screenshot"#拿不到截图路径默认路径
def run(self, result=None):
orig_result = result
if result is None:
result = self.defaultTestResult()
startTestRun = getattr(result, 'startTestRun', None)
if startTestRun is not None:
startTestRun()
self._resultForDoCleanups = result
screenshot_path=getattr(result,"screenshot_path",False)#尝试从result哪里拿到截图目录
if not screenshot_path:
screenshot_path=self.__screenshot_path
result.startTest(self)
testMethod = getattr(self, self._testMethodName)
if (getattr(self.__class__, "__unittest_skip__", False) or
getattr(testMethod, "__unittest_skip__", False)):
# If the class or method was skipped.
try:
skip_why = (getattr(self.__class__, '__unittest_skip_why__', '')
or getattr(testMethod, '__unittest_skip_why__', ''))
self._addSkip(result, skip_why)
finally:
result.stopTest(self)
return
try:
success = False
try:
self.setUp()
except SkipTest as e:
self._addSkip(result, str(e))
except KeyboardInterrupt:
raise
except:
result.addError(self, sys.exc_info())#启动setUp失败直接判断出错
else:
try:
testMethod()
except KeyboardInterrupt:
raise
except (self.failureException,exceptions.WebDriverException):#如果是断言错误或WebDriverException,类型为fail,且增加截图
#增加截图
browser=self.getbrowser()#尝试拿浏览器实例
if browser:
filename=self.__class__.__name__+"_"+self._testMethodName+".png"#格式:类名+方面名称
browser.get_screenshot_as_file(screenshot_path+"\\"+filename)
reback_filename=filename
else:
reback_filename=None
result.addFailure(self, sys.exc_info(),reback_filename)#回传截图名称给report,以便能显示在报告中
except SkipTest as e:#如果为跳过的异常，类型为Skip异常
self._addSkip(result, str(e))
except:#其他类型错误全部为error
result.addError(self, sys.exc_info())
else:
success = True
try:
self.tearDown()
except KeyboardInterrupt:
raise
except:
result.addError(self, sys.exc_info())
success = False
cleanUpSuccess = self.doCleanups()
success = success and cleanUpSuccess
if success:
result.addSuccess(self)
finally:
result.stopTest(self)
if orig_result is None:
stopTestRun = getattr(result, 'stopTestRun', None)
if stopTestRun is not None:
stopTestRun()
def getbrowser(self):
#首先从类属性里面找webdriver实例
for value in self.__class__.__dict__.itervalues():
if isinstance(value,webdriver.Firefox):#如果value是webdriver.Firefox实例
return value
#再从实例属性里面找
for value in self.__dict__.itervalues():
if isinstance(value, webdriver.Firefox): # 如果value是webdriver.Firefox实例
return value
#实在找不到返回None
return None代码很简单，可能也有一些么有考虑到的bug，不过思路就是这样！下面贴出我的单元测试代码的demo:
#coding=utf-8
import IqunxingTest
import HTMLTestRunner
import sys,os
import unittest
from selenium import webdriver
class Mydemo(IqunxingTest.IqunxingTest):
u'''测试百度'''
@classmethod
def setUpClass(cls):
cls.browser=webdriver.Firefox()
@unittest.Myskip
def test1(self):
u'''打开百度'''
browser=self.browser
browser.get("http://www.baidu.com")
@unittest.Myskip
def test2(self):
u'''输入框输入selenium'''
browser = self.browser
browser.find_element_by_id("kw").send_keys("selenium")
@unittest.Myskip
def test3(self):
u'''点击百度一下'''
browser = self.browser
browser.find_element_by_id("su1").click()
if __name__ == '__main__':
module_name=os.path.basename(sys.argv[0]).split(".")[0]
module=__import__(module_name)
runner=HTMLTestRunner.HTMLTestRunner("new.html")
all_suite=unittest.defaultTestLoader.loadTestsFromModule(module)
runner.run(all_suite)注意：由于我们要在报告中显示文档属性，而我们的case使用了装饰器unittest.Myskip，所以我们修改上篇中使用到的Myskip(我的问题，以前没发现点)增加@wraps(func)即可完整代码如下：
from functools import wraps
def Myskip(func):
@wraps(func)
def RebackTest(self):
if self._resultForDoCleanups.failures or self._resultForDoCleanups.errors:
raise unittest.SkipTest("{} do not excute because {} is failed".format(func.__name__,self._resultForDoCleanups.failures[0][0]._testMethodName))
func(self)
return RebackTest
其实上面的testcase还是挺简洁的，我们把工作放在我们的IqunxingTest的run方法里面,当执行test时，AssertError与WebDriverException错误时，自动截图，当然是找到浏览器的实例对象，找不到就不截图了，回传给result也是None，与普通的单元测试无异。
HTMLTestRunner的完整代码如下：（这个代码太长了，实在不想写出该了什么完整贴出来吧！）
#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)
