python pytest 参数化

pytest数据参数化参数化使用

@pytest.mark.parametrize(argnames,argvalues)

argnames：要参数化的变量，string，list，tuple

argvalues：参数化的值，list，list[tuple]

使用string

import pytest
@pytest.mark.parametrize("a,b",[(10,20),(10,30)])
def test_case1(a,b):
    print(a+b)

if __name__ == '__main__':
    pytest.main(["-s","-v",r"E:pythoncodepython_test2021103_test01.py"])

使用tuple

import pytest
@pytest.mark.parametrize(("a","b"),[(10,20),(10,30)])
def test_case1(a,b):
    print(a+b)

if __name__ == '__main__':
    pytest.main(["-s","-v",r"E:pythoncodepython_test2021103_test01.py"])

使用list

import pytest

class Testdata:
    @pytest.mark.parametrize(["a","b"],[(10,20),(10,5),(10,7)])
    def test_demo1(self,a,b):
        a=10
        b=20
        print(a+b)

if __name__ == '__main__':
    pytest.main(["-s","-v",r"E:pythoncodepython_test2021103_test01.py"])

yaml的基本使用安装 pyyaml 库

pip install pyyaml

yaml实现list

list
    - 10
    - 20
    - 30

yaml实现字典

dict
    by:id
    locator:name
    action:click

yaml进行嵌套

-
    - by:id
    - locator:name
    - action: click

companies:
    -
        id:1
        name:company1
        price:200W
    -
        id:2
        name:company2
        price:500W

加载yaml文件

yaml.safe_load(open("./data.yaml"))

pytest数据参数化加载yaml

@pytest.mark.parametrize(["a","b"],yaml.safe_load(open("./data.yaml")))
def test_param(self,a,b):
    print(a+b)

创建data.yaml文件

import pytest
import yaml

class Testdata:
    @pytest.mark.parametrize(["a","b"],yaml.safe_load(open(r"E:pythoncodepython_testdata.yaml")))
    def test_demo1(self,a,b):
        print(a+b)

if __name__ == '__main__':
    pytest.main(["-s","-v",r"E:pythoncodepython_test2021103_test01.py"])
