Pytest 系列（28）- 参数化 parametrize + @allure.title() 动态生成标题

如果你还想从头学起Pytest，可以看看这个系列的文章哦！

https://www.cnblogs.com/poloyy/category/1690628.html

前言

• 参数化 @pytest.mark.parametrize 的学习：https://www.cnblogs.com/poloyy/p/12675457.html
• 默认 allure 报告上的测试用例标题不设置默认就是用例名称，这样可读性不高
• 当结合 @pytest.mark.parametrize 参数化完成数据驱动时，如果标题写死，这样可读性也不高
• 所以我们希望标题可以动态的生成，来看看如何做吧

参数化无标题的栗子

测试代码

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""
__title__  =
__Time__   = 2020/10/28 15:08
__Author__ = 小菠萝测试笔记
__Blog__   = https://www.cnblogs.com/poloyy/
"""
import allure
import pytest

@pytest.fixture()
def login(request):
    """登录"""
    param = request.param
    print(f"账号是：{param['username']}，密码是：{param['pwd']}")
    # 返回
    return {"code": 0, "msg": "success!"}

datas = [
    {"username": "name1", "pwd": "pwd1"},
    {"username": "name2", "pwd": "pwd2"},
    {"username": "name3", "pwd": "pwd3"}
]

@allure.story('登录功能')
@pytest.mark.parametrize('login', datas, indirect=True)
def test_login1(login):
    """
    登录测试用例1
    """
    assert login['code'] == 0

allure 报告

标题就是方法名+参数化的数据，看着可读性就不咋滴

参数化有标题写死的栗子

测试代码

将上面的测试代码添加一个 @allure.title 就可以了

@allure.story('登录功能')
@allure.title('登录测试用例2')
@pytest.mark.parametrize('login', datas, indirect=True)
def test_login2(login):
    """
    登录测试用例2
    """
    assert login['code'] == 0

allure 报告

因为参数化可以生成三条用例，所以三条用例都用了同一个 title，可读性也不咋滴

参数化使用 ids 的栗子

测试代码

#!/usr/bin/env python
# -*- coding: utf-8 -*-

传入的如果是一个字典则显示完整字典值

参数化动态生成标题最优方案的栗子

这种做法的优点

• 可以自定义各式各样的标题
• 单独一个值去维护标题值
• 可读性比较好，容易维护
