pytest文档44-allure.dynamic动态生成用例标题

前言

pytest 结合 allure 描述用例的时候我们一般使用 @allure.title 和 @allure.description 描述测试用例的标题和详情。
在用例里面也可以动态更新标题和详情，使用allure.dynamic方法实现。

allure.dynamic 动态属性

feature 模块

allure.dynamic.feature(feature_name)

功能点 story

allure.dynamic.story(case_story)

用例标题 title

allure.dynamic.title(case_title)

用例描述：请求URL 请求类型 期望结果 实际结果描述

desc = "<font color='red'>请求URL:</font>{}<Br/>" 
           "<font color='red'>请求类型:</font>{}<Br/>" 
           "<font color='red'>期望结果:</font>{}<Br/>" 
           "<font color='red'>实际结果描述:</font>{}<Br/>".format(url,method,expect,expect_result)
allure.dynamic.description(desc)

description 用例描述

可以在测试主体内部动态更新描述 allure.dynamic.description

import allure

@allure.description("""
This description will be replaced at the end of the test.
""")
def test_dynamic_description():
    assert 42 == int(6 * 7)
    allure.dynamic.description('A final description.')

最后用例的描述被更新为 'A final description.'

title 用例标题

用例标题也可以被动态更新

@allure.title("This title will be replaced in a test body")
def test_with_dynamic_title():
    assert 2 + 2 == 4
    allure.dynamic.title('After a successful test finish, the title was replaced with this line.')

最终用例的title更新为'After a successful test finish, the title was replaced with this line.'

参数化

参数化时候，可以使用@allure.title给用例不同标题

@allure.title("Parameterized test title: adding {param1} with {param2}")
@pytest.mark.parametrize('param1,param2,expected', [
    (2, 2, 4),
    (1, 2, 5)
])
def test_with_parameterized_title(param1, param2, expected):
    assert param1 + param2 == expected

也可以在用例里面使用allure.dynamic.title更新用例的标题

def login(username, password):
    '''登录'''
    print("输入账号：%s" % username)
    print("输入密码：%s" % password)
    # 返回
    return {"code": 0, "msg": "success!"}


# 测试数据
test_datas = [
    ({"username": "yoyo1", "password": "123456"}, "success!", "输入正确账号，密码，登录成功"),
    ({"username": "yoyo2", "password": "123456"}, "failed!", "输入错误账号，密码，登录失败"),
    ({"username": "yoyo3", "password": "123456"}, "success!", "输入正确账号，密码，登录成功"),
]


@allure.story("登录用例")
@pytest.mark.parametrize("test_input,expected,title",
                         test_datas
                         )
def test_login(test_input, expected, title):
    '''测试登录用例'''
    # 获取函数返回结果
    result = login(test_input["username"], test_input["password"])
    # 断言
    assert result["msg"] == expected
    allure.dynamic.title(title)

最终生成报告效果
