Ports flomni's ffzp_in()/fosa_in() "skip the move (and, for the FZP, the expensive feedback-disable + reset-enable cycle) if already there" optimization to lamni's lfzp_in()/losa_in(). Also adds the same skip-if-already-there check to losa_out(), which has no flomni equivalent to mirror (fosa_out() always moves unconditionally there) -- added as a lamni-side enhancement per discussion. Checked every existing caller of lfzp_in()/loptics_in() before making this change, since a skip changes behavior for callers that used to get an unconditional reset. Found one real risk: x_ray_eye_align.py's "Step 0: FZP centre" (the start of a fresh alignment run) had its manual feedback disable/enable calls already commented out, meaning it relied entirely on lfzp_in()'s old unconditional reset to establish a correct interferometer zero. flomni's equivalent call site doesn't have this problem because flomni's alignment flow does its own explicit feedback_enable_with_reset() independently beforehand -- lamni's doesn't. Fixed by passing force_feedback_reset=True at that one call site so it keeps its current always-reset behavior; no other lamni caller needed this.

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.
