static void run_interrupt_reset_test ( const struct test_case *  test )

static

Run test to check interrupt is getting triggered when WDT timout ouccured and system reset will not happen since refresh wdt is done.

Parameters

test	Current test case.

static void run_reset_cause_test ( const struct test_case *  test )

static

Run test to check last reset cause.

This test will pass if last reset was caused by a watchdog timeout.

Parameters

test	Current test case.

static void run_wdt_interrupt_test ( const struct test_case *  test )

static

Run test to check interrupt is getting triggered when WDT timout ouccured.

This test will pass if ISR is serviced which is caused by a watchdog timeout.

Parameters

test	Current test case.
