28. 参数化 parametrize @allure.title() 动态生成标题

1. 前言

• 参数化 @pytest.mark.parametrize 的学习 9. 参数化 @pytest.mark.parametrize
• 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

2. 参数化无标题的栗子

2.1 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

2.2 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

3. 参数化有标题写死的栗子

3.1 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

3.2 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

4. 参数化使用 ids 的栗子

4.1 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

5. 参数化动态生成标题的栗子

5.1 测试代码

"""
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

5.2 allure 报告

传入的如果是一个字典则显示完整字典值

6. 参数化动态生成标题最优方案的栗子

6.1 测试代码

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

"""
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)

6.3 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
