python+requests接口自动化框架的实现
为什么要做接口自动化框架
1、业务与配置的分离
2、数据与程序的分离;数据的变更不影响程序
3、有日志功能,实现无人值守
4、自动发送测试报告
5、不懂编程的测试人员也可以进行测试
正常接口测试的流程是什么?
确定接口测试使用的工具----->配置需要的接口参数----->进行测试----->检查测试结果----->生成测试报告
测试的工具:python+requests
接口测试用例:excel
一、接口框架如下:
1、action包:用来存放关键字函数
2、config包:用来存放配置文件
3、TestData:用来存放测试数据,excel表
4、Log包:用来存放日志文件
5、utils包:用来存放公共的类
6、运行主程序interface_auto_test.py
7、Readme.txt:告诉团队组员使用改框架需要注意的地方
二、接口的数据规范设计---Case设计
一个sheet对应数据库里面一张表
APIsheet存放编号;从1开始接口的名称(APIName);请求的url(RequestUrl);请求的方法(RequestMethod);传参的方式(paramsType):post/get请求方法不一样用例说明(APITestCase)是否执行(Active)部分接口已测通,下次不用测试,直接把这里设置成N,跳过此接口
post与get的区别
查看post详情
post请求参数一般是json串,参数放在from表单里面;参数一般不可见,相对来说安全性高些
查看get详情
get请求参数一般直接放在url里面
2.1注册接口用例
RequestData:请求的数据(开发制定的传参方式)RelyData:数据依赖ResponseCode:响应codeResponseData:响应数据DataStore:存储的依赖数据;如果存在数据库里面,在表里增加一个字段用来存依赖的数据(存储的方式是编写接口自动化的人员来设定的存储方式)CheckPoint:检查点Active:是否执行Status:执行用例的状态,方便查看用例是否执行成功ErrorInfo:case运行失败,失败的错误信息;eg:是也本身的原因还是case设置失败,还是其他原因
2.2登录接口用例
RequestData:请求的数据(开发制定的传参方式)RelyData:数据依赖(存储的方式是编写接口自动化的人员来设定的存储方式)ResponseCode:响应codeResponseData:响应数据DataStore:存储的依赖数据;如果存在数据库里面,在表里增加一个字段用来存依赖的数据(存储的方式是编写接口自动化的人员来设定的存储方式)CheckPoint:检查点Active:是否执行Status:执行用例的状态,方便查看用例是否执行成功ErrorInfo:case运行失败,失败的错误信息;eg:是也本身的原因还是case设置失败,还是其他原因
重点说明下RelyData:数据依赖采取的是字典:key:value来存储数据格式;{'request':{'username':'register->1','password':'register->1'},'response':{'code':'register->1'}}
格式化之后:
{ 'request':{ 'username':'register->1', 'password':'register->1' }, 'response':{ 'code':'register->1' }}
三、创建utils包:用来存放公共的类
3.1 ParseExcel.py 操作封装excel的类(ParseExcel.py)
#encoding=utf-8import openpyxlfrom openpyxl.styles import Border, Side, Fontimport timeclass ParseExcel(object): def __init__(self): self.workbook = None self.excelFile = None self.font = Font(color = None) # 设置字体的颜色 # 颜色对应的RGB值 self.RGBDict = {’red’: ’FFFF3030’, ’green’: ’FF008B00’} def loadWorkBook(self, excelPathAndName): # 将excel文件加载到内存,并获取其workbook对象 try: self.workbook = openpyxl.load_workbook(excelPathAndName) except Exception as err: raise err self.excelFile = excelPathAndName return self.workbook def getSheetByName(self, sheetName): # 根据sheet名获取该sheet对象 try: # sheet = self.workbook.get_sheet_by_name(sheetName) sheet = self.workbook[sheetName] return sheet except Exception as err: raise err def getSheetByIndex(self, sheetIndex): # 根据sheet的索引号获取该sheet对象 try: # sheetname = self.workbook.get_sheet_names()[sheetIndex] sheetname = self.workbook.sheetnames[sheetIndex] except Exception as err: raise err # sheet = self.workbook.get_sheet_by_name(sheetname) sheet = self.workbook[sheetname] return sheet def getRowsNumber(self, sheet): # 获取sheet中有数据区域的结束行号 return sheet.max_row def getColsNumber(self, sheet): # 获取sheet中有数据区域的结束列号 return sheet.max_column def getStartRowNumber(self, sheet): # 获取sheet中有数据区域的开始的行号 return sheet.min_row def getStartColNumber(self, sheet): # 获取sheet中有数据区域的开始的列号 return sheet.min_column def getRow(self, sheet, rowNo): # 获取sheet中某一行,返回的是这一行所有的数据内容组成的tuple, # 下标从1开始,sheet.rows[1]表示第一行 try: rows = [] for row in sheet.iter_rows():rows.append(row) return rows[rowNo - 1] except Exception as err: raise err def getColumn(self, sheet, colNo): # 获取sheet中某一列,返回的是这一列所有的数据内容组成tuple, # 下标从1开始,sheet.columns[1]表示第一列 try: cols = [] for col in sheet.iter_cols():cols.append(col) return cols[colNo - 1] except Exception as err: raise err def getCellOfValue(self, sheet, coordinate = None, rowNo = None, colsNo = None): # 根据单元格所在的位置索引获取该单元格中的值,下标从1开始, # sheet.cell(row = 1, column = 1).value, # 表示excel中第一行第一列的值 if coordinate != None: try:return sheet[coordinate] except Exception as err:raise err elif coordinate is None and rowNo is not None and colsNo is not None: try:return sheet.cell(row = rowNo, column = colsNo).value except Exception as err:raise err else: raise Exception('Insufficient Coordinates of cell !') def getCellOfObject(self, sheet, coordinate = None, rowNo = None, colsNo = None): # 获取某个单元格的对象,可以根据单元格所在位置的数字索引, # 也可以直接根据excel中单元格的编码及坐标 # 如getCellObject(sheet, coordinate = ’A1’) or # getCellObject(sheet, rowNo = 1, colsNo = 2) if coordinate != None: try:# return sheet.cell(coordinate = coordinate)return sheet[coordinate] except Exception as err:raise err elif coordinate == None and rowNo is not None and colsNo is not None: try:return sheet.cell(row = rowNo,column = colsNo) except Exception as err:raise err else: raise Exception('Insufficient Coordinates of cell !') def writeCell(self, sheet, content, coordinate = None, rowNo = None, colsNo = None, style = None): #根据单元格在excel中的编码坐标或者数字索引坐标向单元格中写入数据, # 下标从1开始,参style表示字体的颜色的名字,比如red,green if coordinate is not None: try:# sheet.cell(coordinate = coordinate).value = contentsheet[coordinate] = contentif style is not None: sheet[coordinate]. font = Font(color = self.RGBDict[style])self.workbook.save(self.excelFile) except Exception as e:raise e elif coordinate == None and rowNo is not None and colsNo is not None: try:sheet.cell(row = rowNo,column = colsNo).value = contentif style: sheet.cell(row = rowNo,column = colsNo). font = Font(color = self.RGBDict[style])self.workbook.save(self.excelFile) except Exception as e:raise e else: raise Exception('Insufficient Coordinates of cell !') def writeCellCurrentTime(self, sheet, coordinate = None,rowNo = None, colsNo = None): # 写入当前的时间,下标从1开始 now = int(time.time()) #显示为时间戳 timeArray = time.localtime(now) currentTime = time.strftime('%Y-%m-%d %H:%M:%S', timeArray) if coordinate is not None: try:sheet.cell(coordinate = coordinate).value = currentTimeself.workbook.save(self.excelFile) except Exception as e:raise e elif coordinate == None and rowNo is not None and colsNo is not None: try:sheet.cell(row = rowNo, column = colsNo ).value = currentTimeself.workbook.save(self.excelFile) except Exception as e:raise e else: raise Exception('Insufficient Coordinates of cell !')if __name__ == ’__main__’: # 测试代码 pe = ParseExcel() pe.loadWorkBook(r’D:ProgramSourceCodePython Source CodeWorkSpaceInterfaceFrame2018inter_test_data.xlsx’) sheetObj = pe.getSheetByName(u'API') print('通过名称获取sheet对象的名字:', sheetObj.title) # print help(sheetObj.rows) print('通过index序号获取sheet对象的名字:', pe.getSheetByIndex(0).title) sheet = pe.getSheetByIndex(0) print(type(sheet)) print(pe.getRowsNumber(sheet)) #获取最大行号 print(pe.getColsNumber(sheet)) #获取最大列号 rows = pe.getRow(sheet, 1) #获取第一行 for i in rows: print(i.value) # # 获取第一行第一列单元格内容 # print pe.getCellOfValue(sheet, rowNo = 1, colsNo = 1) # pe.writeCell(sheet, u’我爱祖国’, rowNo = 10, colsNo = 10) # pe.writeCellCurrentTime(sheet, rowNo = 10, colsNo = 11)
3.2 封装get/post请求(HttpClient.py)
import requestsimport jsonclass HttpClient(object): def __init__(self): pass def request(self, requestMethod, requestUrl, paramsType,requestData, headers =None, **kwargs): if requestMethod == 'post': print('---', requestData, type(requestData)) if paramsType == 'form':response = self.__post(url = requestUrl, data = json.dumps(eval(requestData)), headers = headers, **kwargs)return response elif paramsType == 'json':response = self.__post(url = requestUrl, json = json.dumps(eval(requestData)), headers = headers, **kwargs)return response elif requestMethod == 'get': request_url = requestUrl if paramsType == 'url':request_url = '%s%s' %(requestUrl, requestData) response = self.__get(url = request_url, params = requestData, **kwargs) return response def __post(self, url, data = None, json = None, headers=None,**kwargs): print('----') response = requests.post(url=url, data = data, json=json, headers=headers) return response def __get(self, url, params = None, **kwargs): response = requests.get(url, params = params, **kwargs) return responseif __name__ == '__main__': hc = HttpClient() res = hc.request('get', 'http://39.106.41.11:8080/getBlogContent/', 'url',’2’) print(res.json())
3.3 封装MD5(md5_encrypt)
import hashlibdef md5_encrypt(text): m5 = hashlib.md5() m5.update(text.encode('utf-8')) value = m5.hexdigest() return valueif __name__ == '__main__': print(md5_encrypt('sfwe'))
3.4 封装Log
import loggingimport logging.configfrom config.public_data import baseDir# 读取日志配置文件logging.config.fileConfig(baseDir + 'configLogger.conf')# 选择一个日志格式logger = logging.getLogger('example02')#或者example01def debug(message): # 定义dubug级别日志打印方法 logger.debug(message)def info(message): # 定义info级别日志打印方法 logger.info(message)def warning(message): # 定义warning级别日志打印方法 logger.warning(message)
3.5 封装发送Email类
import smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartfrom email.header import Headerfrom ProjVar.var import *import osimport smtplibfrom email import encodersfrom email.mime.base import MIMEBasefrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartfrom email.header import Headerfrom email.utils import formataddrdef send_mail(): mail_host='smtp.126.com' #设置服务器 mail_user='testman1980' #用户名 mail_pass='wulaoshi1980' #口令 sender = ’testman1980@126.com’ receivers = [’2055739@qq.com’,'testman1980@126.com'] # 接收邮件,可设置为你的QQ邮箱或者其他邮箱 # 创建一个带附件的实例 message = MIMEMultipart() message[’From’] = formataddr(['光荣之路吴老师', 'testman1980@126.com']) message[’To’] = ’,’.join(receivers) subject = ’自动化测试执行报告’ message[’Subject’] = Header(subject, ’utf-8’) message['Accept-Language']='zh-CN' message['Accept-Charset']='ISO-8859-1,utf-8,gbk' # 邮件正文内容 message.attach(MIMEText(’最新执行的自动化测试报告,请参阅附件内容!’, ’plain’, ’utf-8’)) # 构造附件1,传送测试结果的excel文件 att = MIMEBase(’application’, ’octet-stream’) att.set_payload(open(ProjDirPath+'testdatatestdata.xlsx', ’rb’).read()) att.add_header(’Content-Disposition’, ’attachment’, filename=(’gbk’, ’’, '自动化测试报告.xlsx')) encoders.encode_base64(att) message.attach(att) ''' # 构造附件2,传送当前目录下的 runoob.txt 文件 att2 = MIMEText(open(’e:a.py’,’rb’).read(), ’base64’, ’utf-8’) att2['Content-Type'] = ’application/octet-stream’ att2['Content-Disposition'] = ’attachment; filename='a.py'’ message.attach(att2) ''' try: smtpObj = smtplib.SMTP(mail_host) smtpObj.login(mail_user, mail_pass) smtpObj.sendmail(sender, receivers, message.as_string()) print('邮件发送成功') except smtplib.SMTPException as e: print('Error: 无法发送邮件', e)if __name__ == '__main__': send_mail()
四、 创建config包 用来存放公共的参数、配置文件、长时间不变的变量值
创建public_data.py
import os# 整个项目的根目录绝对路劲baseDir = os.path.dirname(os.path.dirname(__file__))# 获取测试数据文件的绝对路径file_path = baseDir + '/TestData/inter_test_data.xlsx'API_apiName = 2API_requestUrl = 3API_requestMothod = 4API_paramsType = 5API_apiTestCaseFileName = 6API_active = 7CASE_requestData = 1CASE_relyData = 2CASE_responseCode = 3CASE_responseData = 4CASE_dataStore = 5CASE_checkPoint = 6CASE_active = 7CASE_status = 8CASE_errorInfo = 9# 存储请求参数里面依赖的数据REQUEST_DATA = {}# 存储响应对象中的依赖数据RESPONSE_DATA = {}if __name__=='__main__': print(file_path) print(baseDir)
五、创建TestData目录,用来存放测试文件
inter_test_data.xlsx
六、创建action包,用来存放关键字函数
6.1 解决数据依赖 (GetRely.py)
from config.public_data import REQUEST_DATA, RESPONSE_DATAfrom utils.md5_encrypt import md5_encryptREQUEST_DATA = {'用户注册':{'1':{'username':'zhangsan', 'password':'dfsdf23'}, 'headers':{'cookie':'asdfwerw'}}}RESPONSE_DATA = {'用户注册':{'1':{'code':'00'}, 'headers':{'age':2342}}}class GetRely(object): def __init__(self): pass @classmethod def get(self, dataSource, relyData, headSource = {}): print(type(dataSource)) print(dataSource) data = dataSource.copy() for key, value in relyData.items(): if key == 'request':#说明应该去REQUEST_DATA中获取for k, v in value.items(): interfaceName, case_idx = v.split('->') val = REQUEST_DATA[interfaceName][case_idx][k] if k == 'password': data[k] = md5_encrypt(val) else: data[k] = val elif key == 'response':# 应该去RESPONSE_DATA中获取for k, v in value.items(): interfaceName, case_idx = v.split('->') data[k] = RESPONSE_DATA[interfaceName][case_idx][k] elif key == 'headers':if headSource: for key, value in value.items(): if key == 'request': for k, v in value.items():for i in v: headSource[i] = REQUEST_DATA[k]['headers'][i] elif key == 'response': for i, val in value.items():for j in val: headSource[j] = RESPONSE_DATA[i]['headers'][j] return '%s' %dataif __name__ == '__main__': s = {'username': '', 'password': '','code':''} h = {'cookie':'123', 'age':332} rely = {'request': {'username': '用户注册->1', 'password': '用户注册->1'}, 'response':{'code':'用户注册->1'}, 'headers':{'request':{'用户注册':['cookie']},'response':{'用户注册':['age']}} } print(GetRely.get(s, rely, h))
6.2 解决数据存储(RelyDataStore.py)
from config.public_data import RESPONSE_DATA, REQUEST_DATAclass RelyDataStore(object): def __init__(self): pass @classmethod def do(cls, storePoint, apiName, caseId, request_source = {}, response_source = {}, req_headers={}, res_headers = {}): for key, value in storePoint.items(): if key == 'request':# 说明需要存储的依赖数据来自请求参数,应该将数据存储到REQUEST_DATAfor i in value: if i in request_source: val = request_source[i] if apiName not in REQUEST_DATA: # 说明存储数据的结构还未生成,需要指明数据存储结构 REQUEST_DATA[apiName]={str(caseId): {i: val}} else: #说明存储数据结构中最外层结构已存在 if str(caseId) in REQUEST_DATA[apiName]:REQUEST_DATA[apiName][str(caseId)][i] = val else:# 说明内层结构不完整,需要指明完整的结构REQUEST_DATA[apiName][str(caseId)] = {i: val} else: print('请求参数中不存在字段' + i) elif key == 'response':#说明需要存储的依赖数据来自接口的响应body,应该将数据存储到RESPONSE_DATAfor j in value: if j in response_source: val = response_source[j] if apiName not in RESPONSE_DATA: # 说明存储数据的结构还未生成,需要指明数据存储结构 RESPONSE_DATA[apiName]={str(caseId): {j: val}} else: #说明存储数据结构中最外层结构已存在 if str(caseId) in RESPONSE_DATA[apiName]:RESPONSE_DATA[apiName][str(caseId)][j] = val else:# 说明内层结构不完整,需要指明完整的结构RESPONSE_DATA[apiName][str(caseId)] = {j: val} else: print('接口的响应body中不存在字段' + j) elif key == 'headers':for k, v in value.items(): if k == 'request': # 说明需要往REQUEST_DATA变量中写入存储数据 for item in v: if item in req_headers:header = req_headers[item]if 'headers' in REQUEST_DATA[apiName]: REQUEST_DATA[apiName]['headers'][item] = headerelse: REQUEST_DATA[apiName]['headers'] = {item: header} elif k == 'response': # 说明需要往RESPONSE_DATA变量中写入存储数据 for it in v: if it in res_headers:header = res_headers[it]if 'headers' in RESPONSE_DATA[apiName]: RESPONSE_DATA[apiName]['headers'][it] = headerelse: RESPONSE_DATA[apiName]['headers'] = {item: header} print(REQUEST_DATA) print(RESPONSE_DATA)if __name__ == '__main__': r = {'username': 'srwcx01', 'password': 'wcx123wac1', 'email': 'wcx@qq.com'} req_h = {'cookie':'csdfw23'} res_h = {'age':597232} s = {'request': ['username', 'password'], 'response': ['userid'],'headers':{'request':['cookie'], 'response':['age']}} res = {'userid': 12, 'code': '00'} RelyDataStore.do(s, 'register', 1, r, res, req_headers=req_h, res_headers=res_h) print(REQUEST_DATA) print(RESPONSE_DATA)
6.3 校验数据结果(CheckResult.py)
import reclass CheckResult(object): def __init__(self): pass @classmethod def check(self, responseObj, checkPoint): responseBody = responseObj.json() # responseBody = {'code': '', 'userid': 12, 'id': '12'} errorKey = {} for key, value in checkPoint.items(): if key in responseBody:if isinstance(value, (str, int)): # 等值校验 if responseBody[key] != value: errorKey[key] = responseBody[key]elif isinstance(value, dict): sourceData = responseBody[key] if 'value' in value: # 模糊匹配校验 regStr = value['value'] rg = re.match(regStr, '%s' %sourceData) if not rg: errorKey[key] = sourceData elif 'type' in value: # 数据类型校验 typeS = value['type'] if typeS == 'N': # 说明是整形校验 if not isinstance(sourceData, int):errorKey[key] = sourceData else:errorKey[key] = '[%s] not exist' %key return errorKeyif __name__ == '__main__': r = {'code': '00', 'userid': 12, 'id': 12} c = {'code': '00', 'userid': {'type': 'N'}, 'id': {'value': 'd+'}} print(CheckResult.check(r, c))
6.4 往excel里面写结果
from config.public_data import *def write_result(wbObj, sheetObj, responseData, errorKey, rowNum): try: # 写响应body wbObj.writeCell(sheetObj, content='%s' %responseData, rowNo = rowNum, colsNo=CASE_responseData) # 写校验结果状态及错误信息 if errorKey: wbObj.writeCell(sheetObj, content='%s' %errorKey, rowNo=rowNum, colsNo=CASE_errorInfo) wbObj.writeCell(sheetObj, content='faild', rowNo=rowNum, colsNo=CASE_status, style='red') else: wbObj.writeCell(sheetObj, content='pass', rowNo=rowNum, colsNo=CASE_status, style='green') except Exception as err: raise err
七、创建Log目录用来存放日志
八、主函数
#encoding=utf-8import requestsimport jsonfrom action.get_rely import GetRelyfrom config.public_data import *from utils.ParseExcel import ParseExcelfrom utils.HttpClient import HttpClientfrom action.data_store import RelyDataStorefrom action.check_result import CheckResultfrom action.write_result import write_resultfrom utils.Log import *def main(): parseE = ParseExcel() parseE.loadWorkBook(file_path) sheetObj = parseE.getSheetByName('API') activeList = parseE.getColumn(sheetObj, API_active) for idx, cell in enumerate(activeList[1:], 2): if cell.value == 'y': #需要被执行 RowObj = parseE.getRow(sheetObj, idx) apiName = RowObj[API_apiName -1].value requestUrl = RowObj[API_requestUrl - 1].value requestMethod = RowObj[API_requestMothod - 1].value paramsType = RowObj[API_paramsType - 1].value apiTestCaseFileName = RowObj[API_apiTestCaseFileName - 1].value # 下一步读取用例sheet表,准备执行测试用例 caseSheetObj = parseE.getSheetByName(apiTestCaseFileName) caseActiveObj = parseE.getColumn(caseSheetObj, CASE_active) for c_idx, col in enumerate(caseActiveObj[1:], 2):if col.value == 'y': #需要执行的用例 caseRowObj = parseE.getRow(caseSheetObj, c_idx) requestData = caseRowObj[CASE_requestData - 1].value relyData = caseRowObj[CASE_relyData - 1].value responseCode = caseRowObj[CASE_responseCode - 1].value responseData = caseRowObj[CASE_responseData - 1].value dataStore = caseRowObj[CASE_dataStore -1].value checkPoint = caseRowObj[CASE_checkPoint - 1].value #发送接口请求之前需要做一下数据依赖的处理 if relyData: logging.info('处理第%s个接口的第%s条用例的数据依赖!') requestData = GetRely.get(eval(requestData), eval(relyData)) httpC = HttpClient() response = httpC.request(requestMethod=requestMethod, requestData=requestData, requestUrl=requestUrl, paramsType=paramsType ) # 获取到响应结果后,接下来进行数据依赖存储逻辑实现 if response.status_code == 200: responseData = response.json() # 进行依赖数据存储 if dataStore: RelyDataStore.do(eval(dataStore), apiName, c_idx - 1, eval(requestData), responseData) # 接下来就是校验结果 else: logging.info('接口【%s】的第【%s】条用例,不需要进行依赖数据存储!' %(apiName, c_idx)) if checkPoint: errorKey = CheckResult.check(response, eval(checkPoint)) write_result(parseE, caseSheetObj, responseData, errorKey, c_idx) else: logging.info('接口【%s】的第【%s】条用例,执行失败,接口协议code非200!' %(apiName, c_idx))else: logging.info('第%s个接口的第%s条用例,被忽略执行!' %(idx -1, c_idx-1)) else: logging.info('第%s行的接口被忽略执行!' %(idx -1))if __name__=='__main__': main()
