move_and_finish()'s spurious-trip retry (added in 1f85106) couldn't tell a
genuine Galil safety-thread trip apart from a user/scan-initiated stop()
(e.g. Ctrl+C): an aborted move looked like an incomplete move either way,
so the abort got silently undone by resetting the error latches and
re-issuing the original move to the same target.
Track stop() requests on a per-motor threading.Event, cleared at the start
of each move() and checked (twice, since reset_axis_errors() itself takes
a few round-trips) before the retry branch fires, so an aborted move is
now reported as a failure instead of being retried.

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.
