hollerandClaude Sonnet 5 7753dfff38 fix(lamni): port flomni's tomo_reconstruct scan-list fallback and folder resync
- fall back to the last completed scan number when _current_scan_list is
  missing or stale (direct calls outside tomo_scan_projection)
- re-read ptycho_reconstruct_foldername on every write so changes from
  another client session are picked up
- add tests

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.
