lid_switch¶

Source code: lid_switch.py

Tests lid switch functionality.

Description¶

Test lid switch functionality by listening to lid switch event.

Test Procedure¶

If a BFT fixture is set: - ask the fixture to simulate a lid close event - confirm the event is received - ask the fixture to simulate a lid open event - confirm the event is received

If there is no BFT fixture, the operator should close and open the lid manually.

Dependency¶

Depends on ‘evdev’ module to monitor events.
If ok_audio_path is set, depends on audio function to play a sound to indicate the lid close event is received.

Examples¶

LidSwitch is defined in the generic_common test list, it calls this test with default arguments.
