linux.git/tools/testing/selftests/mm/compaction_test.c, branch v6.9 Linux kernel source tree selftests/mm: log a consistent test name for check_compaction 2024-02-22T18:24:57+00:00 Mark Brown broonie@kernel.org 2024-02-09T14:30:04+00:00 f3b7568c49420d2dcd251032c9ca1e069ec8a6c9 Every test result report in the compaction test prints a distinct log messae, and some of the reports print a name that varies at runtime. This causes problems for automation since a lot of automation software uses the printed string as the name of the test, if the name varies from run to run and from pass to fail then the automation software can't identify that a test changed result or that the same tests are being run. Refactor the logging to use a consistent name when printing the result of the test, printing the existing messages as diagnostic information instead so they are still available for people trying to interpret the results.

Every test result report in the compaction test prints a distinct log
messae, and some of the reports print a name that varies at runtime.  This
causes problems for automation since a lot of automation software uses the
printed string as the name of the test, if the name varies from run to run
and from pass to fail then the automation software can't identify that a
test changed result or that the same tests are being run.

Refactor the logging to use a consistent name when printing the result of
the test, printing the existing messages as diagnostic information instead
so they are still available for people trying to interpret the results.

selftests/mm: log skipped compaction test as a skip 2024-02-22T18:24:57+00:00 Mark Brown broonie@kernel.org 2024-02-09T14:30:03+00:00 9c1490d911f8a79b24da0bc1742588fce0e5db41 Patch series "selftests/mm: Output cleanups for the compaction test". A couple of small updates for the check_compaction selftest which make it play more nicely with test automation systems. This patch (of 2): When the compaction test is run it checks to make sure that prerequistives the test requires are available and skips the tests if not. When this happens we log the test as a pass rather than a skip, log as a skip so that the distinction is clear and automation can see unexpected skips.

Patch series "selftests/mm: Output cleanups for the compaction test".

A couple of small updates for the check_compaction selftest which make
it play more nicely with test automation systems.


This patch (of 2):

When the compaction test is run it checks to make sure that prerequistives
the test requires are available and skips the tests if not.  When this
happens we log the test as a pass rather than a skip, log as a skip so
that the distinction is clear and automation can see unexpected skips.
