Title: BabyLIN SDK Example Flow - Open, Load SDF, Start Schedule, Rx Timeout
|
|
|
|
Description:
|
|
Mirrors the vendor example flow: discover/open, load SDF, start a
|
|
schedule, and attempt a receive. Validates that the adapter can perform
|
|
the essential control sequence without exceptions and that the receive
|
|
path is operational even if it times out.
|
|
|
|
Requirements: REQ-HW-OPEN, REQ-HW-SDF, REQ-HW-SCHEDULE
|
|
|
|
Preconditions:
|
|
- ECU_TESTS_CONFIG points to a hardware YAML with interface.sdf_path and schedule_nr
|
|
- BabyLIN_library.py and native libs placed per vendor/README.md
|
|
|
|
Test Steps:
|
|
1. Verify hardware config requests the BabyLIN SDK with SDF path
|
|
2. Connect via fixture (opens device, loads SDF, starts schedule)
|
|
3. Try to receive a frame with a short timeout
|
|
4. Assert no crash; accept None or a LinFrame (environment-dependent)
|
|
|
|
Expected Result:
|
|
- No exceptions during open/load/start
|
|
- Receive returns None (timeout) or a LinFrame
