Pytest相关组件、相关配置文件介绍二

pytest.ini配置文件（作用：用来修改配置pytest默认的运行规则）@H_404_3@

1. pytest.ini放在项目根目录，文件名字固定
2. 常用配置介绍（⚠️不能出现中文注释）

#coding=utf-8

[pytest]

filterwarnings =
   error
   ignore::UserWarning
   ignore:function ham\(\) is deprecated:DeprecationWarning

addopts = -v -s
          --strict
          -m "level0 or level1"
          --cache-clear

norecursedird = .svn -build tmP* .git .idea .pytest_cache

python_files = test_*.py
python_functions = test_run

markers =
    level0 : smoketest
    level1 : systemtest

3. 配置参数含义

• filterwarnings：消除pytest执行警告（从版本开始3.1，pytest现在会在测试执行期间自动捕获警告并在会话结束时显示它们）
• addopts: 更改默认命令行选项,当我们用命令行运行时，需要输入多个参数，可在这里配置（比如：pytest -s test_001.py 配置后只需要 pytest test_001.py)
• norecursedird: pytest收集用例排除的文件
• python_files： 用例收集规则
• python_classes/python_functions： 类/函数收集规则
• markers: 指定mark标签

Demo(采用上面ini文件)@H_404_3@

import pytest


class TestCase001:
    def sum(self, x):
        return x + 3

    def test_001(self):
        assert self.sum(1) == 3

    def test_002(self):
        assert self.sum(2) == 5

    @pytest.mark.level0
    def test_run(self):
        assert sum(5) == 7

=================================== FAILURES ===================================

这里只运行了test_run（在ini中我们指定了python_functions和运行的mark）@H_404_3@
