In auto-rxn, there is a special "fallback" system which is meant to gracefully return all hardware to reasonable positions in the case a reading hits specified limits or there is some other error. We recently discovered that this behavior does NOT work as intended if a daemon crashes [1].
I would like to add tests to auto-rxn to ensure correct behavior when daemons crash. I need crash dummy fake daemons. I can think of a few ways to do this:
- I can add new fake daemons or modify existing daemons to optionally crash. Probably would end up having a config option "crash after X seconds" or "crash after X calls to
get_position".
- I can modify our existing testing decorators [2]. This way any daemon could be set up to crash after X seconds for testing purposes.
- I can write my own special purpose crash dummy daemon and run it via
run_daemon_from_file. This has the advantage of not needing to modify this repo to enable my tests.
Which method is preferred? Do others have testing needs that are similar?
