x01dcandClaude Sonnet 5 f3c90c5b91 fix(lamni): fix three real tomo_scan() crashes, mirroring flomni's fixes
bec.active_account.decode() crashed on every real tomo_scan() call --
active_account is a plain str, not bytes. Flomni's equivalent never had
the .decode() call and already guards an empty active_account (e.g. a
dev/sim session) by skipping sample-database registration instead of
crashing. Same bug fixed in DataDrivenLamNI.tomo_scan() (extra_tomo.py),
which had an identical inline copy.

write_pdf_report() read a nonexistent "mokev" device; the real device is
ccm_energy. Reads it for real now, wrapped in a broad try/except falling
back to "N/A" if unavailable, rather than a hardcoded placeholder.

write_pdf_report()'s logbook/scilog write crashed when scilog isn't
configured -- lamni.py already had this exact tolerance pattern one
method over, in write_to_scilog(); applied the same try/except here.

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.
