Mirko recalled that flomni/lamni check the combined angular spacing adds up
to 180 (360 for lamni) -- found the precise existing pattern in lamni's own
test suite (test_lamni_tomo_angles.py's _assert_equally_spaced(): sort the
combined angles, append a wraparound point at first_angle + range, and
assert every gap including that seam is uniform). This is strictly stronger
than checking the total span alone -- it also catches a double-wide or
missing gap right at the seam, which is exactly the shape of bug flomni's
historical fixes (e.g. 6acaadb, "fix angular start in even subtomos")
addressed.
Ported the same wraparound-inclusive check into OMNY's tests: the existing
full-combination test now asserts it directly, and the intermediate-pairing
helper (_assert_evenly_spaced, used by the type-4 and type-5 pairwise/
progressive combination tests added previously) now includes it too.

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.
