在第一节的时候，讲过，关于pytest执行的参数命令，比如执行用例的时候加上-s参数，就能显示打印内容。-x 遇到错误时停止测试 ，–maxfail=1出现1个失败就终止测试，等等运行条件

if __name__ == '__main__':    pytest.main(["-s -x", "./","--maxfail=1"])

如此多的运行参数，无论是从阅读还是配置都增加了难度。为了让项目运行方式便于管理，pytest专门提供了pytest.ini文件，可以轻松解决上述问题。
pytest.ini 是一个固定文件，也就是说名称不能更改，而且必须存放在项目根目录下。
cmd下使用 pytest -h 命令查看pytest.ini的设置选项

C:\Users\xxx> pytest  -husage: pytest [options] [file_or_dir] [file_or_dir] [...]positional arguments:file_or_dirgeneral:-k EXPRESSION  only run tests which match the given substring expression. An expression is a python evaluatableexpression where all names are substring-matched against test names and their parent classes.Example: -k 'test_method or test_other' matches all test functions and classes whose namecontains 'test_method' or 'test_other', while -k 'not test_method' matches those that don'tcontain 'test_method' in their names. -k 'not test_method and not test_other' will eliminate thematches. Additionally keywords are matched to classes and functions containing extra names intheir 'extra_keyword_matches' set, as well as functions which have names assigned directly tothem. The matching is case-insensitive.-m MARKEXPR    only run tests matching given mark expression.For example: -m 'mark1 and not mark2'.--markers      show markers (builtin, plugin and per-project ones).-x, --exitfirstexit instantly on first error or failed test.--fixtures, --funcargsshow available fixtures, sorted by plugin appearance (fixtures with leading '_' are only shownwith '-v')--fixtures-per-test   show fixtures per test--pdb   start the interactive Python debugger on errors or KeyboardInterrupt.--pdbcls=modulename:classnamestart a custom interactive Python debugger on errors.

addopts

addopts就可以专门解决开篇讲的问题。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 = -s -x --maxfail=1

文章开头的运行代码则可以调整为：

if __name__ == '__main__':    pytest.main(["./"])

addopts只是他的一种用法，还有其他一些经典用法。

testpaths

指定运行的测试用例目录。
如果需要执行多个目录下的，则需要在各个目录中间加入空格。例如运行path1 和 path2 路径下的所有用例：

[pytest]testpaths =  path1 path2

norecursedirs

指定不运行的测试用例目录，和testpaths的效果正好相反，如果是多个目录则用空格隔开。

[pytest]norecursedirs = logs .pytest_cache __pycache__  setting

marks

在之前讲mark 标记测试用例一节的时候，就提到，为了解决使用 @pytest.mark.xxx会出现warning的情况，需要在pytest.ini文件对定义的mark进行解释

[pytest]markers = IOS: run in ios Android:run in AndroidsmokeTest:smokeTest case

log_cli

控制日志文件的输出级别，log_cli=True 输出较为详细日志，包括运行路径。log_cli=False， 输出粗略日志。建议使用log_cli=True

[pytest]log_cli=True
