pytest–参数化

1.参数化方式一
import pytest
# @pytest.mark.parametries("a,b",[(1,2),(2,3),(3,4)])
# @pytest.mark.parametries(("a","b"),[(1,2),(2,3),(3,4)])

class TestDemo:
    @pytest.mark.parametrize("a,b",[(1,2),(2,3),(3,4)])
    def test_param(self,a,b):
        if a==b:
            return True
        else:
            return False

if __name__ == '__main__':
    pytest.main(['test_2.py','-v'])
2.参数化方式二--文件输入
安装PYYML：pip install PYYML
新建data.yml文件 -：列表 key:value 集合

import pytest
import yaml


class TestData:
    @pytest.mark.parametrize(("a", "b"), yaml.safe_load(open("./data.yml")))
    def test_data(self, a, b):
        print(a + b)


if __name__ == '__main__':
    pytest.main(['test_3.py','-v'])
