Record Python interface automation test (first)

The first 2 months learned to use Jmeter+ant to do interface testing, and realized the interface of the batch maintenance management (about 500 cases), the "Interface" and "Interface Test" has a basic understanding, recently found some use Python interface test data, On the one hand, in order to learn how to use Python for interface testing (how to make a simple basic interface test framework), on the other hand in order to exercise how to write code in Python (contact Python for a while, but each time their own programming always have the feeling of forgetting words, really owe practice!! )

First of all, using Python to do interface testing, mainly used is the requests library and JSON library.

1. Start by looking at a simple demo

1 #-*-coding:utf-8-*-2 ImportRequests3Get_url ='HTTP://192.168.0.53:7001/COMMONSERVICE/API/USER/LOGIN.V'4data = {'Usercode':'csqy123456','userpwd':'123456'}5R = Requests.get (Url=get_url, Params=data, timeout=5 #产生一个名为r的Response对象, you can get the information we want from this object; #get请求传参数时, use the params keyword #timeout参数用来设定停止等待响应的时间6 Print(r.url) #返回请求url 7 Print(R.json ()) #以JSON格式解析响应内容8 Print(r.status_code) #返回状态码9 Print(R.raise_for_status ()) #如果发送了一个错误请求, such as 404, 500, can be thrown by raise_for_status () to throw an exception Ten Print(r.encoding) #查看requests使用了什么编码, and you can change it with the R.encoding property  One Print(R.raw) #获取来自服务器的原始套接字响应 A Print(r.headers) #服务器返回给我们的响应头信息, you can also customize the request header by headers=xxx at the time of the parameter transfer  - Print(r.request) #获取原来创建的Request对象 - Print(r.request.headers)#发送到服务器的请求头

1 #-*-coding:utf-8-*-2 ImportRequests 3Post_url ='HTTP://192.168.0.53:7001/COMMONSERVICE/API/CONTROL/STARTBATCHCONTROL/ADD.V'4data = {'Approveseq':'6610','Usercode':'qyzh123456_88','ProjName':'Test Project'}5R = Requests.post (Post_url, Data=payload2, timeout=1)   #get请求传参数时, use the data keyword
6Print(R.json ())7Print(R.status_code)

2. Then use the function call to send the Get/post request

#-*-coding:utf-8-*-ImportRequestsdefsend_get (URL, data):"""define the Send_get function to receive parameters and send get requests"""R= Requests.get (Url=url, params=data) Result=R.json ()returnresultdefsend_post (URL, data):"""define the Send_post function to receive parameters and send a POST request"""R= Requests.get (Url=url, Data=data) Result=R.json ()returnresultdefMain (URL, method, data):"""define a main function that calls Send_post () or Send_get (), depending on whether the method is get or post"""    ifmethod = ='POST': R= Send_post (URL, data)#if it is a POST request, call Send_post ()    Else: R= Send_get (URL, data)#if it is a GET request, call Send_get ()    returnR#return the resultsURL='HTTP://192.168.0.53:7001/COMMONSERVICE/API/CONTROL/CONTROLPROGRESS/QUERY.V'Data= {    'Controlseq':'2018118325'}demo= Main (URL,'GET', data)Print(demo)

3. Define a class that encapsulates the post request and the GET request

#-*-coding:utf-8-*-ImportRequestsImportJSONclassRunmain:"""contains constructors"""    def __init__(Self, URL, method, Data=None): self.t=self.run_main (URL, method, data)defsend_post (self, URL, data): R= Requests.post (Url=url, Data=data) Result=R.json ()returnJson.dumps (result, indent=2, Sort_keys=false, ensure_ascii=False)defsend_get (self, URL, data): R= Requests.get (Url=url, params=data) Result=R.json ()returnJson.dumps (result, indent=2, Sort_keys=false, ensure_ascii=False)#processing return data formats with Json.dumps        #indent=2 indents the output by 2 characters        #Sort_keys=false, whether the output is sorted by keyword        #json.dumps ASCII encoding used by default in Chinese when serializing, Ensure_ascii=false will not output Chinese        #return result    defRun_main (self, URL, method, Data=None):ifmethod = ='GET': R=self.send_get (URL, data)Else: R=self.send_post (URL, data)returnRif __name__=='__main__': URL='HTTP://192.168.0.53:7001/COMMONSERVICE/API/CONTROL/CONTROLPROGRESS/QUERY.V'Data= {        'Controlseq':'2018118325'} Test= Runmain (URL,'GET', data)#because there is a constructor __init__, you need to take parameters when instantiating    Print(TEST.T)

The following is a comparison chart before and after json.dumps use

This concludes with a brief introduction to the usage of the requests, and a basic encapsulation of the post and get requests on the other hand, which is invoked by instantiating the object
