一、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
二、非test文件
pytest里面有些文件是非test文件
- pytest.ini:pytest的主配置文件,可以改变pytest的默认行为
- conftest.py:测试用例的一些fixture配置
- init.py:识别该文件夹为python的package包
pytest.ini配置选项
cmd执行:
pytest --help

pytest.ini文件放在哪里?
就放在项目根目录下 ,不要乱放,不要乱起其他名字
常用配置项
1.marks
作用:测试用例中添加了 @pytest.mark.webtest 装饰器,如果不添加marks选项的话,就会报warnings
格式:list列表类型
写法:
[pytest]
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
2.xfail_strict
作用:设置xfail_strict = True可以让那些标记为@pytest.mark.xfail但实际通过显示XPASS的测试用例被报告为失败
格式:True 、False(默认),1、0
写法:
[pytest]
# mark标记说明
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
xfail_strict = True
具体代码栗子
未设置 xfail_strict = True 时,测试结果显示XPASS
@pytest.mark.xfail()
def test_case1():
a = "a"
b = "b"
assert a != b
图片.png
已设置 xfail_strict = True 时,测试结果显示failed

3.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,一共运行两次,通过分布式去测试,如果在cmd中写的话,命令会很长
pytest -v --rerun=2 --count=2 --html=report.html --self-contained-html -n=auto
每次都这样敲不太现实,addopts就可以完美解决这个问题
[pytest]
# mark
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
xfail_strict = True
# 命令行参数
addopts = -v --reruns=1 --count=2 --html=reports.html --self-contained-html -n=auto
加了addopts之后,我们在cmd中只需要敲pytest就可以生效了!!
4.log_cli
作用:控制台实时输出日志
格式:log_cli=True 或False(默认),或者log_cli=1 或 0

5.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,遇到这种情况,可以使用 norecursedirs 参数简化 pytest 的搜索工作【还是挺有用的!!!】
默认设置: norecursedirs = .* build dist CVS _darcs {arch} *.egg
正确写法:多个路径用空格隔开
[pytest]
norecursedirs = .* build dist CVS _darcs {arch} *.egg venv src resources log report util
更改测试用例收集规则
pytest默认的测试用例收集规则
- 文件名以 test_*.py 文件和 *_test.py
- 以 test_ 开头的函数
- 以 Test 开头的类,不能包含 init 方法
- 以 test_ 开头的类里面的方法
我们是可以修改或者添加这个用例收集规则的;当然啦,是建议在原有的规则上添加的,如下配置
[pytest]
python_files = test_* *_test test*
python_classes = Test* test*
python_functions = test_* test*
