structlog.stdlib.BoundLogger.exception() logs with the method name "exception", which isn't in SEVERITY_MAPPING, so it fell back to the DEFAULT severity. The default BoundLogger is unaffected (it uses "error").

There was a problem hiding this comment.
Could you change the test to:
- Get a logger bound to a stdlib logger
- Call the stdlib-bound logger with an exception (cf. the test just below)
- Assert the output like the other test
You can add the "logger bound with a stdlib logger" as a new fixture into conftests.py ; I suspect it might be useful for other tests as well.
