pytest实现测试用例参数化

@pytest.mark.parametrize(argnames, argvalues)
# 参数：
# argnames:以逗号分隔的字符串
# argvaluse: 参数值列表，若有多个参数，一组参数以元组形式存在，包含多组参数的所有参数
# 以元组列表形式存在

# ./test_case/test_func.py
import pytest

@pytest.mark.parametrize("arg_1", [4399, 2012])
def test_add_by_func_aaa(arg_1):
 print(arg_1)
 
# ./run_test.py
import pytest
