python自動化框架(unnitest+selenium+htmlreport)
上一篇零零散散的寫了一些python unnitest的一些知識，這裏講講我在實際中使用到的自動化測試框架，算是上篇記錄的補充！其實我以爲：什麼框架都無所謂，關鍵是當若是用你的框架發現了bug，能儘可能協助開發解決bug!那麼你最好能夠提供：javascript
1.最基本的錯誤截圖要能提供吧。css
2.要是能提供出錯頁加載的接口信息該多好！（這個是我正在思考的問題）html
3.若是能夠的話，在自動化錄製過程當中，能全程錄製，這樣也利於跟蹤bug（這個應該比較容易實現，畢業屏幕錄製軟件很多，可能須要一個腳本動態啓動他們，結束關閉他們。）java
在這裏我順便扯一句，可能有的公司認爲自動化測試沒什麼價值，緣由：自動化測試根本發現不了什麼太多的bug。可是，個人想法是：python
1、自動化測試核心不是發現多少bug，而是能確保你的項目主流程麼有bug，能正常上線!若是自動化都能發現N個bug，手動人員都不須要測試的了！
web
2、.理論上講自動化能覆蓋全部手動測試的流程，可是你給自動化投入了多少，靠1到2我的？還更不上迭代的進度！瀏覽器
3、對於咱們自動化人員自身而言，也要提升本身，你的價值必定不是隻寫寫腳本，好比搭建環境的能力，搭建web框架的能力，開發桌面應用程序的能力，這些東西都能給手動測試提供便利，也是你的存在感最直接的體現！app
回到正題吧，下面講講個人思路吧，個人想法以下：框架
1.由於測試的是流程，前面的test有問題後面的test我要跳過，執行也沒有意思，可是報告中要體現！ide
2.若是出錯我要能提供準確的截圖。
3.我改寫的unnitest要儘可能方便，不要在寫case上搞一堆的try....except,既不美觀，也一直在寫相同的代碼。根據代碼重構的思想，若是你一直在複製黏貼代碼，你的代碼必定是能夠重構的！
我這裏繼承了unnitest.TestCase類，上篇隨便我說過，unnitest就是TestCase的run方法與TestResult的遊戲，那麼咱們就這樣想，在執行run的時候若是判斷爲AssertError或者WebDriverException咱們認爲是fail，fail就自動截圖(前提能拿到webdriver實例)；若是是其餘的錯誤咱們認爲是error。注意fail和error是不一樣的 ，fail通常是bug(除非你不當心寫錯代碼，致使控件找不到)，error是除了以上2中異常的錯誤，多半是運行錯誤不太多是bug。多半是你本身的代碼寫法有問題。貼出代碼以下：
#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"#拿不到截圖路徑默認路徑 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)#嘗試從result哪裏拿到截圖目錄 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())#啓動setUp失敗直接判斷出錯 else: try: testMethod() except KeyboardInterrupt: raise except (self.failureException,exceptions.WebDriverException):#若是是斷言錯誤或WebDriverException,類型爲fail,且增長截圖 #增長截圖 browser=self.getbrowser()#嘗試拿瀏覽器實例 if browser: filename=self.__class__.__name__+"_"+self._testMethodName+".png"#格式:類名+方面名稱 browser.get_screenshot_as_file(screenshot_path+"\\"+filename) reback_filename=filename else: reback_filename=None result.addFailure(self, sys.exc_info(),reback_filename)#回傳截圖名稱給report,以便能顯示在報告中 except SkipTest as e:#若是爲跳過的異常，類型爲Skip異常 self._addSkip(result, str(e)) except:#其餘類型錯誤所有爲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): #首先從類屬性裏面找webdriver實例 for value in self.__class__.__dict__.itervalues(): if isinstance(value,webdriver.Firefox):#若是value是webdriver.Firefox實例 return value #再從實例屬性裏面找 for value in self.__dict__.itervalues(): if isinstance(value, webdriver.Firefox): # 若是value是webdriver.Firefox實例 return value #實在找不到返回None return None
代碼很簡單，可能也有一些麼有考慮到的bug，不過思路就是這樣！下面貼出個人單元測試代碼的demo:
#coding=utf-8 import IqunxingTest import HTMLTestRunner import sys,os import unittest from selenium import webdriver class Mydemo(IqunxingTest.IqunxingTest): u'''測試百度''' @classmethod def setUpClass(cls): cls.browser=webdriver.Firefox() @unittest.Myskip def test1(self): u'''打開百度''' browser=self.browser browser.get("http://www.baidu.com") @unittest.Myskip def test2(self): u'''輸入框輸入selenium''' browser = self.browser browser.find_element_by_id("kw").send_keys("selenium") @unittest.Myskip def test3(self): u'''點擊百度一下''' 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：因爲咱們要在報告中顯示文檔屬性，而咱們的case使用了裝飾器unittest.Myskip，因此咱們修改上篇中使用到的Myskip(個人問題，之前沒發現點)增長@wraps(func)便可完整代碼以下：
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
其實上面的testcase仍是挺簡潔的，咱們把工做放在咱們的IqunxingTest的run方法裏面,當執行test時，AssertError與WebDriverException錯誤時，自動截圖，固然是找到瀏覽器的實例對象，找不到就不截圖了，回傳給result也是None，與普通的單元測試無異。
HTMLTestRunner的完整代碼以下：（這個代碼太長了，實在不想寫出該了什麼完整貼出來吧！）
#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)
