Root Cause

The caplog fixture did not capture any log messages, often because the logging level is too high or the logger is not configured.

generic

中文

caplog fixture 未捕获任何日志消息，通常是因为日志级别过高或日志记录器未配置。

Workarounds

  1. 95% success 
    caplog.set_level(logging.INFO)
Ensure the logger used in the code under test has propagate=True (default) and is not filtered.
  2. 90% success 
    with caplog.at_level(logging.INFO):
    my_function()
assert 'expected log' in caplog.text

Dead Ends

Common approaches that don't work:

  1. 70% fail

    If the logger is not configured to propagate or the handler is missing, increasing the level may not help.

  2. 90% fail

    This does not test the logging behavior and is not a proper fix.
