XQ#NEWPAR dispatches asynchronously on controller thread 0 and returns as soon as it starts, not once it finishes; the dispatch time varies with controller load. drive_axis_to_limit/find_reference followed it with a fixed sleep before starting XQ#FES/XQ#FRM (also thread 0), which has already needed bumping twice (0.1->0.3, 0.3->0.2) and still raced on lgalil: sending XQ#FES while thread 0 was still busy got a '?' reply (Galil error 19, thread already running). Replace the fixed sleep with _wait_for_thread_idle(0), reusing the existing is_thread_active() primitive (already used the same way in hard_abort_and_restore_positioning_mode) to poll until thread 0 is actually free before dispatching the next routine.

Getting Started with Testing using pytest
BEC is using the pytest framework. It can be installed via
pip install pytest
in your python environment.
We note that pytest is part of the optional-dependencies [dev] of the plugin package.
Introduction
Tests in this package should be stored in the tests directory.
We suggest to sort tests of different submodules, i.e. scans or devices in the respective folder structure, and to folow a naming convention of <test_module_name.py>.
It is mandatory for test files to begin with test_ for pytest to discover them.
To run all tests, navigate to the directory of the plugin from the command line, and run the command
pytest -v --random-order ./tests
Note, the python environment needs to be active.
The additional arg -v allows pytest to run in verbose mode which provides more detailed information about the tests being run.
The argument --random-order instructs pytest to run the tests in random order, which is the default in the CI pipelines.
Test examples
Writing tests can be quite specific for the given function. We recommend writing tests as isolated as possible, i.e. try to test single functions instead of full classes. A very useful class to enable isolated testing is MagicMock. In addition, we also recommend to take a look at the How-to guides from pytest.
