问题描述
我正在尝试为记录器创建单元测试，但是-即使记录了事件-caplog和capsys仍然为空.
I am trying to create unit tests for a logger, but - even though the events are logged - the caplog and capsys remain empty.
我在做什么错了?
推荐答案
事实证明，我的记录器的属性propagate设置为False.结果，这些事件没有转发到pytest添加到根记录器的LogCaptureHandler中.
It turned out that my logger had property propagate set to False. As a result, the events were not forwarded to LogCaptureHandler added by pytest to the root logger.
caplog和capsys都取决于LogCaptureHandler接收传播的事件.
Both caplog and capsys depend on LogCaptureHandler receiving the propagated events.
