对python自动生成接口测试的示例讲解
在python中Template可以将字符串的格式固定下来,重复利用。 同一套测试框架为了可以复用,所以我们可以将用例部分做参数化,然后运用到各个项目中。
代码如下:
coding=utf-8 ''' 作者:大石 功能:自动生成pyunit框架下的接口测试用例 环境:python2.7.6 用法:将用户给的参数处理成对应格式,然后调用模块类生成函数,并将参数传入即可 ''' from string import Template #动态生成单个测试用例函数字符串 def singleMethodCreate(MethodList,interfaceNamePara): code=Template('''\n def test_${testcase}(self): u"""${testcaseName}""" headers = $headers data = $data re = requests.$method(url='$url',headers=headers,data=data) status_code = re.status_code s = str(status_code) json = re.text logging.info('-'*5+'返回状态码是'+s+'-'*5) logging.info('-'*5+'返回结果集是'+json+'-'*5) assert status_code == 200 assert json['status'] == 'ok' ''') string = code.substitute(testcase=MethodList["testcase"],testcaseName=MethodList["TestcaseName"], method=MethodList['method'],url=MethodList['url'],headers=MethodList['headers'],data=MethodList['data'], ) return string #拼接单个的测试用例函数字符串为完整字符串并传回主函数 #MethodParaList获取测试用例部分list def methodCreate(MethodParaList,interfaceNamePara): string = "" for MethodPara in MethodParaList: string2=singleMethodCreate(MethodPara,interfaceNamePara) string=string+string2 return string #构造单个测试集 def singleTestsuitCreate(MethodList,parameters): code = Template('''suite.addTest(${className}("test_${testcase}"))''') string = code.substitute(testcase = MethodList["testcase"],className = parameters[0]) return string #添加测试集 def addtestsuit(MethodParaList,interfaceNamePara): string = "" for MethodPara in MethodParaList: string2 = singleTestsuitCreate(MethodPara,interfaceNamePara) string=string+string2 return string #生成测试用例类函数字符串 def modelClassCreate(parameters): modelCode = methodCreate(parameters[2],parameters[1]) adtestsuit = addtestsuit(parameters[2],parameters) code = Template('''#coding: utf-8 """ 作者:大石 功能:待执行的接口测试用例 环境:python2.7.6 用法:通过框架自动触发调用 """ import unittest,requests,datetime,sys,logging,BSTestRunner,time,os from Log import Log class ${className}(unittest.TestCase): u"""待测试接口:${interfaceName}""" def setUp(self): logging.info('-'*5+"begin test"+"-"*5) def tearDown(self): logging.info('-'*5+"end test"+'-'*5) ${model} if __name__ == "__main__": #解决UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 97: ordinal not in range(128) reload(sys) sys.setdefaultencoding('utf8') #构造测试集 suite = unittest.TestSuite() ${testsuite} #定义date为日期,time为时间 date=time.strftime("%Y%m%d") time1=time.strftime("%H%M%S") now=time.strftime("%Y-%m-%d-%H_%M_%S",time.localtime(time.time())) #创建路径 path='F:/test/study/yaml/test_log/'+now+"/" #解决多次执行时报路径已存在的错误 try: os.makedirs(path) except: if path!= None: logging.error(u'当前路径已经存在') filename=path+'Report.html' fp=file(filename,'wb') #日志记录 Log.log() #执行测试 runner =BSTestRunner.BSTestRunner(stream=fp,title=u'下单平台接口测试用例',description=u'接口用例列表:') runner.run(suite) fp.close() ''') fileStr = code.substitute(className=parameters[0],interfaceName=parameters[1],testsuite=adtestsuit,model=modelCode) f=open(parameters[0]+".py",'w') f.write(fileStr) f.close()
然后测试用例部分如下:
parameters=["Testcase_Orders", "/login", [ {"TestcaseName":"测试登录","method":"post","url":"http://www.senbaba.cn/login","headers":{'content-type': 'application/json', 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko', 'Accept':'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*', 'Accept-Language':'zh-CN'},"data":{"uname":"187071484771","pwd":"123456"}, "testcase":"login"}, {"TestcaseName":"测试登录","method":"post","url":"http://www.senbaba.cn/login1","headers":{'content-type': 'application/json', 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko', 'Accept':'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*', 'Accept-Language':'zh-CN'},"data":{"uname":"187071484771","pwd":"123457"}, "testcase":"login_failed"} ] ]
自动生成的测试用例如下:
#coding: utf-8 """ 作者:大石 功能:待执行的接口测试用例 环境:python2.7.6 用法:通过框架自动触发调用 """ import unittest,requests,datetime,sys,logging,BSTestRunner,time,os from Log import Log class Testcase_Orders(unittest.TestCase): u"""待测试接口:/login""" def setUp(self): logging.info('-'*5+"begin test"+"-"*5) def tearDown(self): logging.info('-'*5+"end test"+'-'*5) def test_login(self): u"""测试登录""" headers = {'Accept-Language': 'zh-CN', 'content-type': 'application/json', 'Accept': 'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*', 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'} data = {'uname': '187071484771', 'pwd': '123456'} re = requests.post(url='http://www.senbaba.cn/login',headers=headers,data=data) status_code = re.status_code s = str(status_code) json = re.text logging.info('-'*5+'返回状态码是'+s+'-'*5) logging.info('-'*5+'返回结果集是'+json+'-'*5) assert status_code == 200 assert json['status'] == 'ok' def test_login_failed(self): u"""测试登录""" headers = {'Accept-Language': 'zh-CN', 'content-type': 'application/json', 'Accept': 'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*', 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'} data = {'uname': '187071484771', 'pwd': '123457'} re = requests.post(url='http://www.senbaba.cn/login1',headers=headers,data=data) status_code = re.status_code s = str(status_code) json = re.text logging.info('-'*5+'返回状态码是'+s+'-'*5) logging.info('-'*5+'返回结果集是'+json+'-'*5) assert status_code == 200 assert json['status'] == 'ok' if __name__ == "__main__": #解决UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 97: ordinal not in range(128) reload(sys) sys.setdefaultencoding('utf8') #构造测试集 suite = unittest.TestSuite() suite.addTest(Testcase_Orders("test_login")) suite.addTest(Testcase_Orders("test_login_failed")) #定义date为日期,time为时间 date=time.strftime("%Y%m%d") time1=time.strftime("%H%M%S") now=time.strftime("%Y-%m-%d-%H_%M_%S",time.localtime(time.time())) #创建路径 path='F:/test/study/yaml/test_log/'+now+"/" #解决多次执行时报路径已存在的错误 try: os.makedirs(path) except: if path!= None: logging.error(u'当前路径已经存在') filename=path+'Report.html' fp=file(filename,'wb') #日志记录 Log.log() #执行测试 runner =BSTestRunner.BSTestRunner(stream=fp,title=u'下单平台接口测试用例',description=u'接口用例列表:') runner.run(suite) fp.close()
20171019添加测试集的一个简单方法:
#添加测试集 def addtestsuit(parameters): string = "" temp = Template('''\n suite.addTest(${className}("test_${testcase}")) ''') l = len(parameters[2]) for i in range(0,l): testcase1 = parameters[2][i]['testcase'] string2 = temp.substitute(className = parameters[0],testcase = testcase1) string=string+string2 print string return string
