Dear Kimi,

Avocado uses stevedore as a plugin system which uses setuptools entry points https://avocado-framework.readthedocs.io/en/latest/Plugins.html#registering-plugins to discover available plugins.

To setup Avocado for development you can simply clone the git repo to any location and use `python setup.py develop --user` (user means use "~/.local" and not "/usr") or simply by our `make develop` or `make link` makefile target (see `make help` for details), which creates "links" in "~/.local/lib". The difference in "install" vs. "develop" is that it won't copy the scripts, it simply tells python that this library is located in this directory, therefor any change in your cloned directory is propagated (apart from new/renamed entry-points which requires to re-execute "make develop").

Note the "develop" puts "avocado" binary to "~/.local/bin/avocado". Using it usually requires extending the PATH, or executing "python3 scripts/avocado" from the cloned git location.

Last but not least, details on installing from git are here: https://avocado-framework.readthedocs.io/en/latest/GetStartedGuide.html#generic-installation-from-a-git-repository

Happy hacking,
Lukáš

PS: Not sure what you require in your testing, there are two debts we have compare to Autotest and that is multi-host testing https://trello.com/c/AnoH6vhP/530-rfc-multiple-machine-support-for-tests and tests surviving host reboot https://trello.com/c/mzhpqQyx/1233-add-avocado-service-to-allow-reboot-between-test-communication-and-even-safer-funcatexit
