配置文件pytest.ini
pytest配置文件可以改变pytest的运行方式，它是一个固定的文件pytest.ini文件，读取配置信息，按指定的方式去运行。
放在项目根目录下，不能改名。

1、markers配置

[pytest]
markers=
  weibo: this is weibo
  toutiao: this is toutiao
  
测试用例中添加了 @pytest.mark.weibo 装饰器，如果不添加marks选项的话，就会报warnings
举例：

import pytest

@pytest.mark.weibo
def test_01():
    print("测试01")

if __name__ == '__main__':
    pytest.main(["-s","test_py01.py"])

"""
结果：如果pytest.ini文件不添加markers
collecting ... collected 1 item

test_py01.py::test_01 

======================== 1 passed, 1 warning in 0.01s =========================

Process finished with exit code 0
PASSED


结果：如果pytest.ini文件添加markers
collecting ... collected 1 item

test_py01.py::test_01 PASSED                                             [100%]测试01


============================== 1 passed in 0.01s ==============================
"""



2、设置xfail_strict = True可以让那些标记为@pytest.mark.xfail 实际通过显示XPASS的测试用例被报告为失败
[pytest]
xfail_strict=False


import pytest
@pytest.mark.xfail
def test_01():
    a = "a"
    b = "b"
    assert a!=b

if __name__ == '__main__':
    pytest.main(["-s","test_py01.py"])
"""
结果：
collecting ... collected 1 item

test_py01.py::test_01 XPASS                                              [100%]

============================= 1 xpassed in 0.01s ==============================
"""


[pytest]
xfail_strict=True

"""
结果：
test_py01.py::test_01 FAILED                                             [100%]
order\test_py01.py:6 (test_01)
[XPASS(strict)] 
"""



3、addopts参数可以更改默认命令行选项，这个当我们在cmd输入一堆指令去执行用例的时候，就可以用该参数代替了，省去重复性的敲命令工作
[pytest]
addopts= -v --html=report.html


import pytest
def test_01():
    a = "a"
    b = "b"
    print(a,b)
    assert a!=b

cmd命令行运行：pytest test_01.py
"""
结果：自动带上参数-v --html=report.html
collected 1 item

test_py01.py::test_01 FAILED                                                                                     [100%]

====================================================== FAILURES =======================================================
_______________________________________________________ test_01 _______________________________________________________
[XPASS(strict)]

=============================================== short test summary info ===============================================

================================================== 1 failed in 0.06s ==================================================
"""



4、log_cli控制台实时输出日志
log_cli=True 或False（默认），或者log_cli=1 或 0

[pytest]
lig_cli=True

import pytest
def test_01():
    a = "a"
    b = "b"
    print(a,b)
    assert a!=b

if __name__ == '__main__':
    pytest.main(["-s","test_py01.py"])

"""
结果：
collecting ... collected 1 item

test_py01.py::test_01 PASSED                                             [100%]a b

======================== 1 passed, 1 warning in 0.01s =========================
