Pytest（14）pytest.ini配置文件

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

pytest -h

pytest一定要放在项目的根目录，名字也要命名为pytest.ini

作用：测试用例中添加了 @pytest.mark.web装饰器，如果不添加marks选项的话，就会报warnings 写法

[pytest]
markers =
  app:  Run the app case
  web:  Run the web case

作用：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

比如：想测试完生成报告，失败重跑两次，如果在bash中写的话，命令会很长

pytest -v --reruns=2 --alluredir ./report --clean-alluredir

每次输入这么多，不太好记住，于是可以加到pytest.ini里

[pytest]
markers =
  app:  Run the app case
  web:  Run the web case
addopts = -v --reruns=2 --alluredir ./report --clean-alluredir

这样我下次打开cmd，直接输入pytest，它就能默认带上这些参数了

作用：pytest 收集测试用例时，会递归遍历所有子目录，包括某些你明知道没必要遍历的目录，一般情况下项目的用例都放在case文件夹下，所以除了case文件夹，其他项目的路径都可以不必递归

默认设置： norecursedirs = . build dist CVS _darcs {arch} .egg 正确写法：在上面默认值后面加上除了case的所有路径，多个路径用空格隔开(一)

norecursedirs = .* build dist CVS _darcs {arch} *.egg API common configFile data logs report

查看pytest -h 查看命令行参数找到 [pytest] ini-options

• python_files (args) 匹配 python 用例文件， 如test_.py、 _test.py
• python_classes (args) 匹配 class 类名称 如Test*.py
• python_functions (args) 匹配函数和class里面方法 如test_

假如我们想把匹配规则改为函数名以best_*开头

[pytest]

python_files =  test_*.py
python_classes = Test*
python_functions = best_*

这样以后pytest就匹配的都是以best开头的用例了
