Hook函数之参数化生成用例

• • • 前言
    • pytest_generate_tests
    • • conftest.py
      • 编写case

前言

• 本篇来学习pytest中使用Hook函数–pytest_generate_tests实现参数化

pytest_generate_tests

• 在 conftest.py 自定义参数化的钩子, 判断当测试用例传了 param 参数，就让它生成参数化的用例

conftest.py

# -*- coding: utf-8 -*-
# @Time    : 2021/10/14
# @Author  : 大海
# conftest.py

def pytest_generate_tests(metafunc):
    """ generate (multiple) parametrized calls to a test function."""
    if "param" in metafunc.fixturenames:
        metafunc.parametrize("param",
                             metafunc.module.test_data,
                             ids=metafunc.module.names,
                             scope="function")

编写case

# -*-coding:utf-8一*-
# @Time：2022/10/14
# @Author:  大海
# test_71.py

import os
import requests

# 用例的id名称
names = ["get 1", "get 2"]

# 测试数据 list of dict
test_data = [
    "url": "https://postman-echo.com/get",
    "method": "GET",
    "headers":
        
            "Content-Type": "application/json"
        ,
    "json":
        
            "username": "test1",
            "password": "123456"
        

,
    
        "url": "https://postman-echo.com/get",
        "method": "GET",
        "headers":
            
                "Content-Type": "application/json"
            ,
        "json":
            
                "username": "test2",
                "password": "123456"
            

    
]


def test_get_request(param):
	"""测试get请求"""
    r = requests.session().request(**param)
    print('\\nrsp', r.text)

    user_name = r.json().get('args').get('username')
    print('user_name', user_name)
    assert 'test' in user_name


if __name__ == '__main__':
    os.system('pytest -s -v test_71.py')
