1、标记mark说明

pytest支持自定义标记，自定义标记可以把一个web项目划分成多个模块，然后指定模块名执行
再比如：我们可以指定哪些用例是windows下执行的，哪些用例是mac下执行的，然后在代码运行的时候指定mark即可

2、代码演示

# test_01.py
import pytest


@pytest.mark.weibo
def test_weibo():
    print("===正在测试微博===")


@pytest.mark.toutiao
def test_toutiao():
    print("===正在测试头条===")


@pytest.mark.toutiao
def test_toutiao2():
    print("===再次测试头条===")


@pytest.mark.xinlang
def test_skip():
    print("===正在测试新浪===")


def test_no_mark():
    print("===没有打标记===")

3、指定模块运行

执行标记为weibo的用例
```
pytest -s -m xinlang test_01.py
```

执行结果

避免结果中的warming

创建pytest.ini文件，需要与运行的用例同一个目录下，或者根目录作用于全局

加上自定义mark，如下即可

[pytest]
markers = 
	weibo: this is weibo page
	toutiao: this is toutiao page
	xinlang: this is xinlang page

不想执行标记为xinlang的用例

pytest -s -m "not xinlang" test_01.py
