Pytest learning ----- pytest Interface Association framework encapsulation of interface automation testing

In general , We're going through one yaml File association implementation

Create a new file in the root directory yaml, Through the above conftest.py File to update global variables :

1. First, you need to create a read 、 write in 、 eliminate yaml File tool class

as follows ：

import os

import yaml


class YamlUnit:
    def readAllYaml(self):
        with open(os.getcwd() + "/extract.yml", mode='r', encoding='utf-8') as f:
            value = yaml.load(stream=f, Loader=yaml.FullLoader)
            return value

    def readKeyYaml(self,key):
        with open(os.getcwd() + "/extract.yml", mode='r', encoding='utf-8') as f:
            value = yaml.load(stream=f, Loader=yaml.FullLoader)
            return value[key]

    def writeYaml(self, data):
        with open(os.getcwd() + "/extract.yml", mode='w', encoding='utf-8') as f:
            print(os.getcwd() + "/extract.yml")
            value = yaml.dump(data=data, stream=f, allow_unicode=True)

    def deleteYaml(self):
        with open(os.getcwd()+"/extract.yml",mode="w",encoding='utf-8') as f:
            f.truncate()

2. coordination conftest.py file + fixture Implement global shared calls

#  Realize partial pre 
import pytest

from comment.yaml_unit import YamlUnit


@pytest.fixture(scope="function")
def conn_getbase():
    print(" Successfully connected to database ")
    yield
    print(" Closing database succeeded ")


@pytest.fixture(scope="session", autouse=True)
def clear_yaml():
    YamlUnit().deleteYaml()


@pytest.fixture(scope="session", autouse=True)
def get_token():
    token = '';  #  obtain token Code request for 
    return token

3. When calling, just pass in the method function name

Such as ： Before using the following functions, you need to connect to the database , Just incoming conftest.py In the document conn_getbase The function name is just

   def test_Login(self,conn_getbase):
        # post request 
        url = "xxxxxxx"
        #  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)
