CI for csaxs_bec / test (push) Failing after 2m12s
fix(flomni,lamni): fovy/piezo-range bounds didn't match scan's strict "<"
Real hardware failure: flomni.fovy=100.0 was accepted by the property, GUI,
and CLI (all capped at an inclusive 100.0), but FlomniFermatScan's own
ScanArgument requires fovy strictly less than 100 -- so the scan rejected it
at runtime with ScanInputValidationError, only surfacing once actually run.

- flomni.fovy property setter: now raises at >=100 (was >100), matching
  FlomniFermatScan's gt=0/lt=100. GUI/CLI max tightened 100.0 -> 99.9.
- lamni_piezo_range_x/y (become LamniFermatScan's fovx/fovy, gt=0/lt=80):
  found the same bug class at BOTH ends while writing the regression test --
  GUI/CLI min was an inclusive 0.0 (scan requires strictly >0) and max was
  an inclusive 80.0 (scan requires strictly <80). Tightened to 0.1-79.9 in
  both GUI and CLI. Property setter's large_range_scan bypass left
  untouched per earlier explicit instruction -- this fixes the GUI/CLI
  entry points, which is where the bound is actually enforced in practice.
- Added test_fov_bounds_match_scan_args.py: introspects the real
  ScanArgument gt/ge/lt/le from FlomniFermatScan/LamniFermatScan and asserts
  our configured GUI/CLI ranges are strictly inside them, so this class of
  bug (passes every check except the one that actually runs the scan)
  can't silently come back for these or future fields.

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.
