Subject: [PATCH v2] tst: Provide test for sched_rr_get_interval
Date: Mon, 8 Feb 2021 10:42:52 +0100 [thread overview]
Message-ID: <20210208094252.17086-1-lukma@denx.de> (raw)
This change adds new test to assess sched_rr_get_interval's
functionality.
To be more specific - following use cases are checked:
- If the read interval is correct
- If the proper ABI is used - to check if adjacent data is not
overwritten
---
Changes for v2:
- Move test execution from tests to xtests
- Use TEST_VERIFY_EXIT () macro instead of if () clause with FAIL_EXIT1 ()
