test-actions:
- action-brief: |
Start a period, reset the CPU usage counters and then
call ${../if/period:/name} again. This second call will
invoke ``_Rate_monotonic_Update_statistics()`` and enter the
``if()`` otherwise not reached.
After each call to ${../if/period:/name}, ${../if/period-status:/name}
will be called in order to check that the period status recovers from
the reset with the start of the second period.

- brief: |
Check the first call to ${../if/period-status:/name} is not
defined due to the preceding reset of the CUP usage counters.

- brief: |
Check that the second call to ${../if/period-status:/name} is not
longer affected by the reset of the CUP usage counters in the
previous period.
