當(dāng)我們寫(xiě)用例斷言時(shí)，往往一個(gè)斷言結(jié)果是不夠的，所以需要加入多重?cái)嘌裕嘀財(cái)嘌?，?dāng)斷言中間出現(xiàn)斷言結(jié)果False時(shí)，會(huì)中斷后續(xù)的斷言執(zhí)行，會(huì)導(dǎo)致測(cè)試用例執(zhí)行結(jié)果的準(zhǔn)確性不高
使用pytest框架的插件pytest-assume, 實(shí)現(xiàn)用例執(zhí)行時(shí)，其中一個(gè)斷言失敗后，執(zhí)行后續(xù)的斷言

安裝：pip install pytest-assume

以下為使用示例：

import pytest
from pytest_assume.plugin import assume
  
class TestTwo:
    def test001(self):
        with assume:
            assert True
        with assume:
            assert 1 == 2
 
    def test002(self):
        assert 1 == 1
 
if __name__ == '__main__':
    pytest.main(['-v', 'test_002.py'])

我們很容易在以下信息中找出相應(yīng)的日志信息：

在行有E標(biāo)記的信息中，我們可以清晰看到提示 pytest_assume.plugin.FailedAssumption: 1 Failed Assumptions
