Introduction: I participated in a background system development project at the beginning of the year, which involved many interfaces. As a tester of the project team, I need to test these interfaces. It is very convenient to use postman tools to test at the beginning. However, with the increase of the number of interfaces, it is not only necessary to perform manual click testing, but also, once the interface parameters change, re-change the interface parameters, more times, resulting in a serious decline in testing efficiency.

Later, I turned my attention to automated testing, considering that the project team had high requirements for interface quality and needed rapid development. Finally, python is selected as the script development language, its own requests and urllib modules are used for interface requests, the optimized unittest test framework is used to write test interface functions, the test results are displayed by HTMLTestRunner framework, and the ssl module of python is used to support the verification of https protocol. Next, I introduce these modules in detail and give the complete test code for each module.

1. API request

Python, especially the urllib and requests modules in python 3.x, are the two main modules used to request url. In these two modules, if it is only a url request that supports http protocol, it is recommended to use requests module. Why would you say that? Because Einstein said: simplicity is beauty. The requests module encapsulates the urllib module again, which makes it more convenient to use. The module supports GET, POST, PUT, DELETE and other request methods. The request return information includes the status code and the message body, which is represented by three digits, and the message body can be expressed in string, binary or json format. Let's use an example to introduce the use of the requests module. The code is as follows:

Import requests

Def get_method (url, para, headers):

Try:

Req = requests.get (url=url, params=para, headers=headers)

Except Exception as e:

Print (e)

Else:

If req.status_code = "200":

Return req

Else:

Print ("Requests Failed.")

If _ _ name__=='__main__':

Url = "http://www.google.com"

Req = get_method (url=url, para=None, headers=None)

Print (req.status_code)

Print (req.text)

The output is:

two hundred
