pytest之@pytest.mark.parametrize实例讲解

在测试用例的前面加上：
@pytest.mark.parametrize("参数名",列表数据)
参数名：用来接收每一项数据，并作为测试用例的参数。
列表数据：一组测试数据。

#====参数为列表嵌套字典====
import pytest

def secend(c,b):
    add= int(b)+int(c)
    print(add)
    return add

@pytest.mark.parametrize('case',[{'b':'34','c':'56'},{'b':'39','c':'56'}])
def test_1(case):
    pp=case
    tt=secend(**case)
    print("测试账号：%s" % tt)


if __name__ == "__main__":
    pytest.main(["-s", "1.py"])

运行结果：
