网上http接口自动化测试Python实现有很多，我本人也是在网上途径学了一点相关课程。然后运用到工作中，在这里我进行下总结，相当于工作总结吧，有不对的地方或者写的不清楚的地方。希望大神帮忙指出~

做测试或者做开发的都知道常用的接口测试工具有 postman、jmeter等，在使用这些工具的时候我们就知道常用的接口类型，还有请求类型。比如我用的post 、 get请求。关于post、get请求的区别，大家可以参考网上的其他博客。我后期可能会根据自己的理解专门写一篇关于post、get的文章好了闲话不多说我们进入正题吧

1、脚本所需的库

requests python第三方库用于访问网络资源

安装方法：

pip install requests

如果是用ide 在里面可以直接安装 unittest 单元测试框架不仅可以适用于单元测试，还可以适用WEB自动化测试用例的开发与执行

2、结构目录

3、封装http请求

一般我都会封装基类用于较少重复多余的代码

class RunMain(): #发送post请求 def send_Post(self,url,data): result = requests.post(url= url,data= data).json() res = json.dumps(result ,ensure_ascii= False , sort_keys= True , indent= 2) return res #发送get请求 def send_Get(self,url,data): result = requests.get(url=url, data=data).json() res = json.dumps(result, ensure_ascii=False, sort_keys=True, indent=2) return res #根据method来判断是 post请求还是 get请求 def run_main(self,method ,url = None ,data = None): result = None if method == 'post': result = self.send_Post(url,data) elif method == 'get': result = self.send_Get(url,data) else: print("method值错误") return result

4、封装发送邮件的基类

有时候我们的测试报告需要发送给开发人员或者其他人员，这时候就需要我们脚本去发送邮件了

#SMTP 服务器主机 mail_host = localReadConfig.get_email('mail_host') #指定 SMTP 服务使用的端口号 mail_port = localReadConfig.get_email('mail_port') #用户名 mail_user = localReadConfig.get_email('mail_user') #邮件密码授权码 mail_pass = localReadConfig.get_email('mail_pass') #邮件发送方邮箱地址 sender = localReadConfig.get_email('sender') #接受邮件放邮箱地址 value = localReadConfig.get_email('receiver') title = localReadConfig.get_email('subject') content = localReadConfig.get_email('content') class Email(): def __init__(self): self.receiver = [] #获取接收人列表 for r in str(value).split('/'): self.receiver.append(r) #格式化时间 data = datetime.now().strftime("%Y-%m-%d %H:%M:%S") self.subject = title+" "+data self.msg = MIMEMultipart('mixed') def config_header(self): #设置邮件发送头 self.msg['Subject'] = self.subject self.msg['From'] = sender self.msg['To'] = ":".join(self.receiver) def config_content(self): #设置邮件主题 content_plain = MIMEText(content,'plain') self.msg.attach(content_plain) def config_file(self): #如果有文件，就配置邮件附件 filename 用英文形式，如果用中文需要改动 if self.check_file(): htmlpath = os.path.join(getPath.get_basepath(),'result','report.html') html = open(htmlpath,'rb').read() filehtml = MIMEText(html,'base64','utf-8') filehtml['Content-Type'] = 'application/octet-stream' filehtml['Content-Disposition'] = 'attachment; filename="test.html"' self.msg.attach(filehtml) def check_file(self): #判断文件是否存在如果存在则返回 True 反之返回 False reportpath = os.path.join(getPath.get_basepath(),'result','report.html') if os.path.isfile(reportpath) and not os.stat(reportpath) == 0: return True else: return False def send_email(self): self.config_header() self.config_content() self.config_file() try: smtp = smtplib.SMTP() smtp.connect(mail_host,mail_port) smtp.login(mail_user, mail_pass) smtp.sendmail(sender, self.receiver, self.msg.as_string()) smtp.quit() print('邮件已发送注意查收') except Exception as ex: print('邮件发送失败，错误详情：'+str(ex))

5、封装读取配置文件的基类

#获取文件路径 basepath = getpath.get_basepath() config_path = os.path.join(basepath,'config\config.ini') config = configparser.ConfigParser() config.read(config_path) class ReadConfig(): #获取名字为 [HTTP] 的属性值 def get_http(self,name): value = config.get('HTTP' , name) return value def get_email(self,name): value = config.get('EMAIL' , name) return value def get_database(self,name): value = config.get('DATABASE' , name) return value

6、生成HTML的基类这个类网上有很多我这是最原始的有兴趣的朋友可以去美化

#生成测试报告相关 """ 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) ------------------------------------------------------------------------ Copyright (c) 2004-2007, Wai Yip Tung All rights reserved.

7、配置读取测试用例的基类

一个接口传参可能有很多，设计测试用例的时候我们考虑会很多正常的不正常的等等

class ReadExcel(): def get_xls(self,xls_name,sheet_name): cls = [] #拼接文件路径 xlsPath = os.path.join(basepath,'test_file','case',xls_name) #打开文件 login.xls file = open_workbook(xlsPath) #获取sheet 也就是 login.xls文件的 sheet名字 sheet = file.sheet_by_name(sheet_name) #获取行数 nrows = sheet.nrows for i in range(nrows): if sheet.row_values(i)[0] != u'case_name': #获取整行整列的值返回必须是数字所以上面有空的 cls数组 cls.append(sheet.row_values(i)) return cls

贴上测试用的excel 代码中的 sheet 指的就是 excel中的 login

8、编写配置文件

我们创建一个新文件夹创建 config.ini 文件格式如下

9、编写项目路径基类

import os def get_basepath(): #获取文件路径 basepath = os.path.split(os.path.realpath(__file__))[0] return basepath

10、编写测试类

login_xls = readExcel.ReadExcel().get_xls("login.xls","login") url = readConfig.ReadConfig().get_http("loginurl") @paramunittest.parametrized(*login_xls) class testUserLogin(unittest.TestCase): def setParameters(self,case_name,path,data,method): self.case_name = str(case_name) self.path = str(path) self.data = str(data) self.method = str(method) def description(self): self.case_name def setUp(self): print(self.case_name + "测试开始前准备") #调用测试方法 def testLogin(self): self.checkResult() def tearDown(self): print("测试结束，输出log完结\n\n") def checkResult(self): #将读取到的 data 转为 json格式 data = json.loads(self.data) #调用 configHTTP 类中的run_main方法 info = RunMain().run_main(self.method,url+self.path,data) #将得到的返回值进行格式化并取值判断 print(info) res = json.loads(info) if self.case_name == "login": self.assertEqual(res['code'],200) if self.case_name == "login_error": self.assertEqual(res['code'],404) self.assertEqual(res['msg'], '密码错误') if self.case_name == "login_null": self.assertEqual(res['code'],404)

因为接口定义只接受json格式的参数所以我们在读取到excel中数据的时候需要将其转换为json格式

data = json.loads(self.data)

调用 configHTTP类中的 RunMain()方法返回值就是接口的返回值我们处理返回值就可以得到我们想要的数据例如脚本中

self.assertEqual(res['code'],200)

将返回值中的code 与 200 比较看看是否相等，如果不相等则结果错误查看日志 setUp() 方法让我们可以在测试开始之前进行数据的准备 testLogin（）就是我们测试的主方法 tearDown（）测试结束之后执行的放我们所有的打印类容都可以在网页中查看

11、编写总运行发放

import os import common.HTMLTestRunner as HTMLTestRunner import common.configEmail as configEmail import read.readConfig as readConfig import getPath import unittest basepath = getPath.get_basepath() report_path = os.path.join(basepath,'result') class AllTest: def __init__(self): global resultPath resultPath = os.path.join(report_path,'report.html') self.caseListFile = os.path.join(basepath,'test_file\caselist.txt') self.caseFile = os.path.join(basepath,'test_case') self.caseList = [] def set_case_list(self): """ 读取caselist.txt文件中的用例名称，并添加到caselist元素组 :return: """ fb = open(self.caseListFile) for value in fb.readlines(): data = str(value) # 如果data非空且不以#开头 if data != '' and not data.startswith('#'): # 读取每行数据会将换行转换为\n，去掉每行数据中的\n self.caseList.append(data.replace("\n","")) fb.close() def set_case_suite(self): # 通过set_case_list()拿到caselist元素组 self.set_case_list() test_suite = unittest.TestSuite() suite_module = [] # 从caselist元素组中循环取出case for case in self.caseList: # 通过split函数来将user/login_case分割字符串，-1取后面，0取前面 case_name = case.split("/")[-1] # 打印出取出来的名称 print(case_name+'.py') # 批量加载用例，第一个参数为用例存放路径，第一个参数为路径文件名参考这个 https://blog.csdn.net/happyuu/article/details/80683161 discover = unittest.defaultTestLoader.discover(self.caseFile, pattern=case_name+'.py',top_level_dir=None) # 将discover存入suite_module元素 suite_module.append(discover) # 判断suite_module元素组是否存在元素 if len(suite_module)>0: # 如果存在，循环取出元素组内容，命名为suite for suite in suite_module: # 从discover中取出test_name，使用addTest添加到测试集 for test_name in suite: test_suite.addTest(test_name) else: return None return test_suite def run(self): try: # 调用set_case_suite获取test_suite suit = self.set_case_suite() # 判断test_suite是否为空 if suit is not None: # 打开result/report.html测试报告文件，如果不存在就创建 fp = open(resultPath,'wb') # 调用HTMLTestRunner 这个文件不用管网上有可以直接下载的 runner = HTMLTestRunner.HTMLTestRunner(stream=fp,title="测试报告",description="测试说明") runner.run(suit) else: print("没有案例可以测试") finally: on_off = readConfig.ReadConfig().get_email('on_off') if on_off =='on': configEmail.Email().send_email() elif on_off == 'off': print('发送邮件已关闭') fp.close() if __name__=="__main__": AllTest().run()

这里需要编写一个caselist 用于存放该类需要运行那些测试用例不需要运行的我们可以注释起来最后为大家献上所有源码仅供参考 ps：有些功能还没写完~ 接口测试
