当一次用例执行完成后，如果其中存在失败的测试用例，那么我们可以使用此命令重新运行失败的测试用例
pytest test_004.py
============================================== 2 failed, 1 passed in 0.18s ===============================================
2个失败一个成功
pytest --lf
只会重新执行失败的2个用例
=================================================== 2 failed in 0.19s ====================================================
屏蔽测试用例输出的回溯信息，可以简化失败用例的输出信息。style可以时‘auto‘, ‘long‘, ‘short‘, ‘no‘, ‘line‘, ‘native‘
