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！

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 -*- """ __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"} ] ids = [ "username is name1,pwd is pwd1", "username is name2,pwd is pwd2", "username is name3,pwd is pwd3" ] @allure.story('登录功能') @pytest.mark.parametrize('login', datas, ids=ids, indirect=True) def test_login1(login): """ 登录测试用例1 """ assert login['code'] == 0
allure 报告
参数化动态生成标题的栗子
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"} ] data2 = [ ("name1", "123456"), ("name2", "123456"), ("name3", "123456") ] @allure.story('分别传值') @allure.title('登录测试用例2-账号是：{username}-密码是：{pwd}') @pytest.mark.parametrize('username,pwd', data2) def test_login1(username, pwd): """ 登录测试用例1 """ print(username, pwd) @allure.story('字典参数化') @allure.title('登录测试用例2-{dict}') @pytest.mark.parametrize('dict', datas) def test_login2(dict): """ 登录测试用例1 """ print(dict['username'], dict['pwd']) @allure.story('传值进fixture') @allure.title('登录测试用例2{login}') @pytest.mark.parametrize('login', datas, indirect=True) def test_login3(login): """ 登录测试用例2 """ assert login['code'] == 0
allure 报告
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
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 data = [ ("name1", "123456", "name1 登录成功"), ("name2", "123456", "name2 登录失败"), ("name3", "123456", "name3 登录成功") ] @allure.story('分别传值') @allure.title('登录测试用例-{title}') @pytest.mark.parametrize('username,pwd,title', data) def test_login1(username, pwd, title): """ 登录测试用例1 """ print(username, pwd)
allure 报告
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
