根因分析

使用caplog fixture捕获日志消息，但指定的日志记录器名称不存在或未配置，因此未捕获到任何日志记录。

English

The caplog fixture is used to capture log messages, but the specified logger name does not exist or has not been configured, so no log records are captured.

解决方案

  1. 90% 成功率 Verify the logger name used in the code under test and match it in caplog 
    In the test:
import logging
logger = logging.getLogger('myapp')
logger.info('test message')
with caplog.at_level(logging.INFO, logger='myapp'):
    # run code
    assert 'test message' in caplog.text
  2. 85% 成功率 Use caplog.set_level() to enable capturing for all loggers 
    caplog.set_level(logging.DEBUG)
# Now all log messages are captured
assert 'expected message' in caplog.text

无效尝试

常见但无效的做法:

  1. Using caplog.clear() before capturing logs 50% 失败

    This clears existing logs but does not fix the logger name issue.

  2. Setting the log level to DEBUG globally 40% 失败

    This may generate more logs but does not ensure the correct logger is captured.
