5011

Verify Nled Registry Settings:

This test verifies that the NLED registry settings are correctly configured.

5012

6000

NLED Service Event Path Mapping Test:

This test verifies that Event -> LED path mapping works by setting the event and corresponding NLED number in the registry [HKEY_LOCAL_MACHINE\Services\NLEDSRV\Config\...] and it also verifies that the NLED is activated when the corresponding event occurs.

6001

NLED Service Blinking Test:

This test updates the registry for each NLED to either ON/OFF/BLINK and verifies that the NLED behaves as expected when the trigger event occurs. It also verifies that if an NLED is configured to blink but no blink parameters are set, then the NLED will blink with default parameters.

6002

NLED Service Blink Settings Test:

This test updates the blink setting values in the registry for an NLED that is capable of blinking and it then verifies that the NLED blinks with those settings.

6007

NLED Service Blink Off Test:

  1. This test raises the event of an NLED to turn it ON/OFF/BLINK through NLED Service and checks if the state of the NLED is changing accordingly or not. And it then invokes the Core DLL NLED APIs to change the state of the same NLED. And it then checks that NLED service and NLED driver handle this scenario gracefully.

7002

NLED CPU Utilization Test:

Checks that the increase in CPU utilization when all the NLEDs are blinking does not exceed a predefined limit.

7004

NLED Blink Control Library Blink OFF Blink Test:

Sets all NLEDs to BLINK state, and then turns the NLEDs to OFF one by one and lets only one of the NLEDs in the blinking state. And it then verifies if the last NLED still continues to Blink or not.

7005

NLED Blink Control Library Verify Blink Time Test:

Checks if the NLED being blinked by the Blink Ctrl library is blinking with correct timing or not.

7006

NLED Blink Control Library Check System behavior Test:

This test continuously changes the values of the members of struct NLED_SETTINGS_INFO and makes the NLED/NLEDs to Blink/ON/OFF and checks whether the BlinkCtrl Library handles this scenario gracefully or not.
