标签:lin   cookie   header   flask框架   核心   模板   .text   interface   模版   

设计原理   基于http协议接口的测试设计,莫过于Python的requests库,简单粗暴易理解。

设计模式   采用python的flask框架,搭建一套接口自动化测试平台。   测试用例维护:采用Excel   测试结果保存:采用MongoDb存储,HTML页面展示

相关核心代码介绍:

  1.   Excel模板如下: 技术分享图片   看Excel的定义命名,基本理解,每个参数的含义   介绍:   B1:要测试的接口地址   B2:该测试接口的请求参数,以“#”分隔【便于分割】   B3:登录的URL,若测试不需要登录   B4:登录的json串,以字典的形式展现   注:CaseNo、Except——result、Commit,是必填的
  2.   从Excel读取及处理数据,代码如下:

            try:
                excel = xlrd.open_workbook(sFile)

  3.   requests的post和get请求代码:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    import requests
     
    def postRequest(url, data, cookie):
        header={"Content-Type":"application/json"}
        if cookie:
            return requests.post(url, data=data, cookies=cookie, headers = header)
        else:
            return requests.post(url, data=data, headers = header)
     
    def postRequest(url, cookie):
        header={"Content-Type":"application/json"}
        if cookie:
            return requests.get(url, cookies=cookie, headers = header)
        else:
            return requests.get(url, headers = header)
  4.   检查返回为页面还是json串:
    1
    2
    3
    4
    5
    6
    7
    def checkReturnResult(req_result):
        try:
            realResult = eval(req_result)
        except:
            return False
        else:
            return req_result
  5.   测试结果存储MongoDB:

    # -*- coding: utf-8 -*-
    import pymongo
    class ConMongoDb:
        #读取配置文件
        def __init__(self):
            MongoIP="192.168.X.XXX"
            MongoPort=27017
            #链接MongoDb
            self.conn = pymongo.Connection(MongoIP, MongoPort)
            #选择数据库
            self.db = self.conn.test
            self.collection = self.db.SocketTest
     
        ‘‘‘
        # **************************************************
        # InsertMongo:往MongoDb插入数据
        # **************************************************
        ‘‘‘
        def InsertMongo(self, Lst):
            self.collection.insert(Lst)
      def close(self):      return self.conn.disconnect()
     
  6. 测试用例执行代码:

    import time
    ExcelSheet = ExcelSheet("104137PC.xlsx")
    interFace = ExcelSheet.get_interFace()
    interFaceArgList = ExcelSheet.get_interFaceArgList()
    titleIndex = ExcelSheet.get_titleIndex()
    loginInterFace = ExcelSheet.get_loginInterFace()
     
    # 判断是否需要登录
    if loginInterFace:
        if "username" not in titleIndex or "password" not in titleIndex:
            print "Test Case File not include username or password"
            exit()
        else:
            # 获取登录接口参数的json
            loginJson = ExcelSheet.get_loginJson()
     
    caseList = list()
    for line in range(5, ExcelSheet.nrows()):
        lineContent = ExcelSheet.get_by_line(line)
        # 获取登录后的cookie
        if loginInterFace:
            # 需要登录,用户名密码,替换
            loginJson = loginJson.replace("#username#", lineContent["username"])
            loginJson = loginJson.replace("#password#", str(lineContent["password"]))
            result = postRequest(loginInterFace, eval(loginJson), False)
            print result.text
            cookie = result.cookies
        else:
            cookie = False
     
        # reqtype 不填默认post
        if lineContent.has_key("reqtype"):
            if lineContent["reqtype"].upper() == "POST":
                interFaceResult = postRequest(interFace, lineContent["data"], cookie)
            else:
                interFaceResult = postRequest(interFace, cookie)
        else:
            interFaceResult = postRequest(interFace, lineContent["data"], cookie)
     
        req_result = interFaceResult.text
     
        # 非页面,可直接比较,也可以转换成字典进行某个value进行比较
        if checkReturnResult(req_result):
            if checkReturnResult(req_result) == lineContent["Except_result"]:
                TestResult = "PASS"
            else:
                TestResult = "FAIL"
        #如果返回是页面的话,就查找特殊标志词
        else:
            if ineContent["Except_result"] in req_result:
                TestResult = "PASS"
            else:
                TestResult = "FAIL"
     
        lineContent["result"] = TestResult
     
        caseList.append(lineContent)
    TestDate = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time()))
    content = {"interFace": interFace, "caseList": caseList, "testdate": TestDate}
     
    MyngoCls = ConMongoDb()
    MyngoCls.InsertMongo(content)
    MyngoCls.close()

整个流程梳理:

  • 用例Excel的读取解析
  • python的requests模块运用
  • 返回值的判断处理
  • 用例执行结果的存储
  • 用例测试的入口
