Output of simpletest run with current main branch:

42085.612: INFO - Default handler: Info message

42085.612: ERROR - Stream Handler: Error message

  Traceback (most recent call last):

      raise RuntimeError("Test exception handling")
  
  RuntimeError: Test exception handling
  

Output of the simpletest run in cpython modified to use logging instead of this library:

Stream Handler: Error message
Test exception handling
Traceback (most recent call last):
  File "/home/timc/repos/circuitpython/Adafruit_CircuitPython_Logging/examples/logging_simpletest.py", line 29, in <module>
