• Pytest(14)pytest.ini配置文件


    前言

    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
     

    查看pytest.ini的配置选项

    pytest -h
    

    找到以下内容

    注意

    pytest一定要放在项目的根目录,名字也要命名为pytest.ini
     

    mark标记

    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
    

    addopts

    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
     

    norecursedirs

    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
    

    自定义匹配规则

    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
