The unit tests and linter rely on tox and a recent version of Python 3 (at least 3.9).
Run tox with no arguments to run all of the tests. Use one of the
specific target environments for running fewer or different
tests. Refer to tox.ini for the list of possible targets.
The e2e directory contains test scripts that run in pipelines in CI
to test behaviors of the entire system. Each script includes a comment
at the top explaining what the test is trying to demonstrate.
Log messages should be all lower case.
When possible, log messages should be prefixed with the name of the distribution being processed.
Information about long running processes should be logged using the "unit of work" pattern. Each long step should be preceded and followed by log messages writing to INFO level to show what is starting and stopping, respectively.
Detailed messages should be logged to DEBUG level so they will not appear on the console by default.
