一般情况下，我们是通过一个yaml文件进行关联实现

在根目录下新建一个文件yaml，通过上述conftest.py文件实现全局变量的更新:

1.首先需要建立一个读取、写入、清除yaml文件的工具类

如下：

import osimport yamlclass 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 valuedef 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.配合conftest.py文件+ fixture实现全局共享调用

# 实现部分前置
import pytestfrom comment.yaml_unit import YamlUnit@pytest.fixture(scope="function")
def conn_getbase():print("连接数据库成功")yieldprint("关闭数据库成功")@pytest.fixture(scope="session", autouse=True)
def clear_yaml():YamlUnit().deleteYaml()@pytest.fixture(scope="session", autouse=True)
def get_token():token = '';  # 获取token的代码请求return token

3.调用时只需传入方法函数名称即可

如：下面函数使用之前需要连接数据库，只需传入conftest.py文件里面的conn_getbase函数名即可

   def test_Login(self,conn_getbase):# post请求url = "xxxxxxx"# 参数data = {"captcha": "Gkak!@#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)
