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":"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,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
