006、pytest中有多个断言时，第1个断言失败的话后面的代码(包括第2个断言)不会再执行，跳到下一条测试用例。

 

pytest中有多个断言时，前面的断言失败的话，后面的代码不会再执行，跳到下一条测试用例。

 

实例代码如下：

import pytest
from loguru import logger


# 被测试函数
def str_to_int(str_param: str):
    if str_param.isdigit():
        results = int(str_param)
    else:
        results = '非int字符串，不能转化为int'
    return results


# 测试数据
cases_list = [
    ('', '非int字符串，不能转化为int'),
    ('1234', 1234),
    ('abc', '非int字符串，不能转化为intaa'),
    ('3.14', '非int字符串，不能转化为int')
]


@pytest.mark.parametrize('item', cases_list)
def test_str_to_int(item):
    assert str_to_int(item[0]) == item[1]       # 如果在这里断言失败了，后面的代码不会执行，跳到下一条测试用例。
    logger.info("aaaaaaaaaaaa")
    a = 1
    assert 1 == a

 

执行结果如下，只有3个 aaaaaaaaaaa 输出 ：
