这篇文章将为大家详细讲解有关如何在pytest中使用pytest.ini配置文件,文章内容质量较高,因此小编分享给大家做个参考,希望大家阅读完这篇文章后对相关知识有一定的了解。
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
查看pytest.ini的配置选项
cmd执行
pytest --help
找到这部分内容

就放在项目根目录下 ,不要乱放,不要乱起其他名字
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
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
collecting ... collected 1 item
02断言异常.py::test_case1 XPASS [100%]
============================= 1 xpassed in 0.02s ==============================
已设置 xfail_strict = True 时,测试结果显示failed
collecting ... collected 1 item 02断言异常.py::test_case1 FAILED [100%] 02断言异常.py:54 (test_case1) [XPASS(strict)] ================================== FAILURES =================================== _________________________________ test_case1 __________________________________ [XPASS(strict)] =========================== short test summary info =========================== FAILED 02断言异常.py::test_case1 ============================== 1 failed in 0.02s ==============================
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!!
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
log_cli=0的运行结果
log_cli=1的运行结果
很明显,加了log_cli=1之后,可以清晰看到哪个package下的哪个module下的哪个测试用例是否passed还是failed;
所以平时测试代码是否有问题的情况下推荐加!!!但如果拿去批量跑测试用例的话不建议加,谁知道会不会影响运行性能呢?
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
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*
