pytest自定义动态添加描述信息动态Description

pytest自定义动态添加描述信息动态Description实现截图：

参考：https://www.cnblogs.com/yhleng/p/11225638.html

要动态传参__doc__内容也是可以的.可以通过__doc__动态修改描述.

 普通方法:   方法名.__doc__='fixture parameters.'

 实例方法:   self.方法名.__func__.__doc__='fixture parameters.'     **实例方法必须加__func__否则是只读的.**

# -*- coding: UTF-8 -*-
import pytest
import json
import requests

stations = json.loads(open('./param/StationParams.json', 'r',encoding='utf-8').read())

def setup():
    print("setup_function：每个用例开始前都会执行1")

def teardown():
    print("teardown_function：每个用例结束后都会执行")

@pytest.fixture(params=stations)
def stations(request):
    return request.param

def station(stations):
    # 添加描述信息
    test_station.__doc__ = stations['desc']

    requestParam = json.dumps(stations)
    # 请求的链接
    url = 'xxxx - 隐藏url'
    print("请求参数：\n" + requestParam)
    # 发送请求
    r = requests.post(url, requestParam, headers={'Content-Type': 'application/json'})
    print("返回结果：\n" + r.content.decode('utf-8'))
    return r

def test_station(stations):
    station(stations)
    status = station(stations).status_code
    responseDict = json.loads(station(stations).content)
    assert status == 200
    assert station(stations).content
    assert int(responseDict['msgCode']) == 100

下面是参数：

 [
    {
      "channel": "12qwe",
      "stationType": 0,
      "useRange": 1,
      "version": "1.2",
      "desc": "正确的参数：高铁自营站点"
    },
    {
      "channel": "12qwe",
      "stationType": 0,
      "useRange": 2,
      "version": "1.2",
      "desc": "正确的参数：高铁联营站点"
    },
    {
      "channel": "",
      "stationType": 0,
      "useRange": 2,
      "version": "1.2",
      "desc": "错误的参数：少了渠道号"
    }
  ]
