Voltage-changing tests can't sleep a fixed amount and assume the
rail is there — Owon settling is bench-dependent and typically
asymmetric (up-step ≠ down-step). New shared helpers and tests use
the rail's measured value to drive timing.
- tests/hardware/psu_helpers.py:
wait_until_settled(psu, target_v, ...)
polls measure_voltage_v() until within tol, returns
(elapsed_s, trace) or (None, trace) on timeout
apply_voltage_and_settle(psu, target_v, validation_time, ...)
composite: set setpoint → wait until measured matches →
sleep validation_time so the firmware-side observer can
detect and republish status. Raises on settle timeout.
downsample_trace, plus DEFAULT_VOLTAGE_TOL_V (0.10),
DEFAULT_POLL_INTERVAL_S (0.05), DEFAULT_SETTLE_TIMEOUT_S (10.0),
DEFAULT_VALIDATION_TIME_S (1.0).
- test_overvolt.py: voltage-tolerance suite. Each test (over,
under, parametrized sweep) uses apply_voltage_and_settle for the
procedure, the autouse _park_at_nominal fixture (also via the
helper), and a single deterministic ALM_Status read after the
validation hold instead of polling-the-bus.
- test_psu_voltage_settling.py: characterization test, opt-in via
the new psu_settling marker. Walks four (start_v, target_v)
transitions and records settling_time_s + voltage_trace per case.
Values feed directly into test_overvolt's ECU_VALIDATION_TIME_S
budgeting.
- pytest.ini:
junit_family = legacy → record_property() entries now actually
appear in reports/junit.xml (the default xunit2 silently
dropped them with a collect-time warning, breaking the
conftest plugin's metadata round-trip)

The MUM (Melexis Universal Master) adapter is the current default; the
BabyLIN SDK adapter is retained only for backward compatibility with
existing rigs.
Code:
- Emit DeprecationWarning when BabyLinInterface is instantiated and
when tests/conftest.py routes interface.type=='babylin' to it.
- Update module/class docstrings in ecu_framework/{__init__,config,
lin/__init__,lin/babylin}.py to label BabyLIN-specific fields and
paths as deprecated.
Config / scripts / pytest:
- pytest.ini: relabel the babylin marker as deprecated.
- config/{babylin.example,examples,test_config}.yaml: add deprecation
banners and field comments.
- scripts/99-babylin.rules and scripts/pi_install.sh: annotate the
udev-rule install block as legacy-only.
Documentation:
- TESTING_FRAMEWORK_GUIDE.md, docs/08_babylin_internals.md, and
vendor/README.md: prepend explicit "DEPRECATED" banners.
- docs/{README,01,02,04,05,07,09,10,12,13,14,15,18,DEVELOPER_COMMIT_
GUIDE}.md: relabel "legacy" to "deprecated" where babylin is
mentioned, present MUM as the primary path, and steer new work
toward the MUM examples.
No tests, configs, or modules were deleted; existing BabyLIN setups
keep working but now produce a clear DeprecationWarning at runtime.
