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='$url',headers=headers,data=data) status_code = re.status_code s = str(status_code) json = re.text logging.info('-'*5+'返回状态码是'+s+'-'*5) logging.info('-'*5+'返回结果集是'+json+'-'*5) assert status_code == 200 assert json['status'] == 'ok'''') string = code.substitute(testcase=MethodList["testcase"],testcaseName=MethodList["TestcaseName"], method=MethodList['method'],url=MethodList['url'],headers=MethodList['headers'],data=MethodList['data'], ) return string #拼接单个的测试用例函数字符串为完整字符串并传回主函数#MethodParaList获取测试用例部分listdef methodCreate(MethodParaList,interfaceNamePara): string = "" for MethodPara in MethodParaList: string2=singleMethodCreate(MethodPara,interfaceNamePara) string=string+string2 return string #构造单个测试集def singleTestsuitCreate(MethodList,parameters): code = Template('''suite.addTest(${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,osfrom Log import Logclass ${className}(unittest.TestCase): u"""待测试接口：${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":"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,osfrom Log import Logclass 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

以上这篇对python自动生成接口测试的示例讲解就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
