一、直接在标签上传参：
一个参数多个值
@ pytest.mark.parametrize("参数", (参数值1, 参数值2, 参数值3))示例：
import pytest
# 单个参数的情况
@pytest.mark.parametrize("a", (1, 2, 3, 4))
def test_add(a):print("\na的值")结果：
============================= test session starts =============================

多个参数多个值的情况
# 单个参数的情况
# 格式：@pytest.mark.parametrize("参数",参数值)
@pytest.mark.parametrize("a", (1, 2, 3, 4))
def test_add(a):print("\na的值")# 多个参数多个值的情况
# 格式：@pytest.mark.parametrize("参数a, 参数b",([a1, b1],[a2,b2],[a3, b3]))
@pytest.mark.parametrize("b,c,d", ([1, 2, 3], [4, 5, 6], [7, 8, 0]))
def test_add2(b, c, d):print('\nb,c,d的值分别为：', f'{b}, {c}, {d}')二、数据结构
列表（list）形式
# 单个参数的情况
data1 = [1, 2, 3, 4]@pytest.mark.parametrize("a", data1)
def test_add(a):print('\na的值：', a)# 多个参数多个值得情况data2 = [(1, 2, 3),(4, 5, 6),(0, 8, 9)
]@pytest.mark.parametrize("a,b,c", data2)
def test_add2(a, b, c):print('\na,b,c的值分别为：', f'{a},{b},{c}')
输出
