Pytest learning ----- detailed explanation of the request for interface automation test

One 、 Interface automation implementation

Tool classes realize interface automation ：

1.Postman+Newman+git/svn+jenkins
2.jmeter+Ant+git/svn+jenkins

Build a code framework to realize interface automation ：

Use the development language + Tool class ： Such as Java、Python

Two 、 Why do you build an interface automation framework

1. agile development , When iterating over a product project , Generally, the number of interfaces is relatively large , It is convenient for the team to realize interface test version control .（ Main cause ）
2. The function of the tool is too rigid , Some interfaces are completely impossible to implement （ For example, complex encryption interface , Signature interface, etc ,postman Only use md5 encryption ）
3. There are many interfaces with different protocols in the interface project .
4. It's difficult to make mistakes , Inconvenient positioning , It needs to be combined with packet capturing .
5. There is no way to generate beautiful test reports , Especially for outsourcing companies .
6. Multiple interfaces in series , Database validation , Log monitoring, etc
7. Some companies do web automation + Interface automation .

3、 ... and 、Python+requests The module realizes interface automation

1.requests Third party libraries are mainly used to send http request , Interface automation

install requests library ：pip install requests

2.requests Overall view

request ：

1.requests.get() send out get request
2.requests.post() send out post request
3.requests.delete() send out delete request
4.requests.put() send out put request
5.requests.request() The core approach

Respond to ：

import requests
rep = requests.request()
# Return string data 
print(rep.text)
# Returns data in dictionary format 
print(rep.json())
# Return status code 
print(rep.status_code)
# return cookies
print(rep.cookies)
# Returns the encoding format 
print(rep.encoding)
# Return response header 
print(rep.headers)

3. Interface practice

Request mode ：get、post、delete、put
Request parameter type ： Key value pair 、JSON Format 、 File format .

import time

import pytest
import requests


# class  setup_class:

class TestSendRequsets:

    # def setup(self):
    #     print(" Before each use case is executed ")
    # def teardown(self):
    #     print(" After each use case is executed ")
    # @pytest.fixture()
    def test_getImgCode(self):
        #  Interface url
        t = time.time()
        timess = str(int(round(t * 1000)))
        times = str(int(t))
        url = "http://124.71.230.185:9002/jeecg-boot/sys/randomImage/" + "" + timess
        #  Parameters 
        data = {
            "_t": times,
        }
        # # get request 
        rep = requests.request('get', url, params=data)
        print(rep.text)

    #  Only execute smoke
    # @pytest.mark.smoke
    def test_Login(self):
        # post request 
        url = "http://124.71.230.185:9002/jeecg-boot/sys/login"
        #  Parameters 
        data = {
            "captcha": "[email protected]#2019",
            "checkKey": 1637811815838,
            "password": "123456",
            "remember_me": 1,
            "username": "admin"
        }
        rep = requests.request('post', url, json=data)
        statues = rep.json()["success"]
        message = rep.json()["message"]
        if statues:
            print(message)
        else:
            # raise Exception(message)
            print(message)


if __name__ == '__main__':
    pytest.main(['-vs']);

Use case management framework ： install pytest
pip install pytest

The default rules ：

1. Test file with test End or already test start
2. Test function to test_ start
3. Test method with Test start , But not with init() Method ;

Be careful ：

get Request by params Pass parameters
post Request by json perhaps data Pass parameters , The difference is that ：
data:
The data packet dict Dictionary type ： By default, the request header is application/x-www-form-urlencoded, Said to form Form transmission , Format a=1&b=2&c=3
json：
The data packet ： Whether it's dict Type or str type , The default is application/json, Format {"a":1,"b":2}
json.dumps(data), serialize , Convert data in dictionary format into str Data of type
json.loads(data), Deserialization , hold str Convert format to dictionary format .
