It seems both tests failed at the public demo test for sensor data timed out:

E _queue.Empty: Sensor data retrieval timed out (60 seconds)

.tox/default/lib/python3.10/site-packages/self_driving_lab_demo/utils/observe.py:108: Empty

Does the test rely on the actual light demo to run?

That's correct, though new microcontroller code still needs to be manually uploaded to the public test demo (currently in the office with the 3D printer). The tests failing is a known (and somewhat recent) issue, which I've been meaning to debug. It seems to be specific to the GitHub Actions unit tests, which makes it more slower and more difficult to troubleshoot.

• Tests keep failing even though HF space and colab notebook are fine #254
