Yes, this looks very useful. Should be able to retire at least one shell one-liner from my history!
This adds a new `--trace-output` option to `run-tests.py` which mimics the same option already in `run-multitests.py`. Using it, the output from the test running on a board is printed to stdout as it is received. This allows easier debugging of tests, to see the output in real time. For tests that have complicated run parameters, eg using via-mpy or needing a target wiring script, running them standalone (eg with `mpremote`) is not possible, so using `run-tests.py` becomes mandatory, hence the need to easily see the output without having to view the result file separately at the end. It's also useful to watch tests that pass but are long running. Signed-off-by: Damien George <damien@micropython.org>
