Test cases are ordered the same as theoption arrays and help message to allow easy checking of whether alloptions are covered.This should help clarify what the proper command line behavior of RTLAis in case there are holes in the documentation and verify that theintended behavior is implemented correctly.A few necessary changes to the unit tests were done as part of thiscommit:- Unit tests now also link to libsubcmd and its dependencies.- A new global variable in_unit_test is added to RTLA's CLI interface, causing it to skip check for root if running in unit tests. This allows the CLI unit tests to run as non-root, like existing unit tests.There is quite a lot of duplication, some of it is mitigated with macros,but partially it is intentional so that future changes in behavior aretracked across tools.Link: https://lore.kernel.org/r/20260528103254.2990068-6-tglozar@redhat.comSigned-off-by: Tomas Glozar <tglozar@redhat.com> List of files: /linux/tools/tracing/rtla/tests/unit/timerlat_top_cli.c Thu, 28 May 2026 12:32:53 +0200 Tomas Glozar <tglozar@redhat.com>
