Try turning on logging of DEBUG level messages. This may be done a number of ways, depending on what it is you’re testing:
If you’re testing the database unit tests, then set the environment variable LOGGING_LEVEL=DEBUG. This may be done like so:
LOGGING_LEVEL=DEBUG python run_tests.py
This variable replaces the older HYPERDBDEBUG environment var.
If you’re testing a particular tracker, then set the logging level in your tracker’s config.ini.
Set to a filename and roundup will write each email message that it sends to that file instead to the internet. This environment variable is independent of the python -O flag.
