perf test perftool_testsuite: Use absolute paths

2025-10-01T12:44:05+00:00

Test cases from perftool_testsuite are affected by the current directory where the test are run. For this reason, the test driver has to change the directory to the base_dir for references to work correctly. Utilize absolute paths when sourcing and referencing other scripts so that the current working directory doesn't impact the test cases.

perf test perftool_testsuite: Return correct value for skipping

2025-01-14T17:57:20+00:00

In 'perf test', a return value 2 represents that the test case was skipped. Fix this value for perftool_testsuite test cases to differentiate between skip and pass values.

perf tools tests shell base_probe: Enhance print_overall_results to print summary information

2024-12-18T19:24:31+00:00

Currently print_overall_results prints the number of fails in the summary, example from base_probe tests in testsuite_probe: ## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY :: 11 failures found test_invalid_options contains multiple tests and out of that 11 failed. Sometimes it could happen that it is due to missing dependency in the build or environment dependency. Example, perf probe -L requires DWARF enabled. otherwise it fails as below: ./perf probe -L Error: switch `L' is not available because NO_DWARF=1 "-L" is tested as one of the option in: for opt in '-a' '-d' '-L' '-V'; do <> print_results $PERF_EXIT_CODE $CHECK_EXIT_CODE "missing argument for $opt" Here -a and -d doesn't require DWARF. Similarly there are few other tests requiring DWARF. To hint the user that missing DWARF could be one issue, update print_overall_results to print a comment string along with summary hinting the possible cause. Update test_invalid_options.sh and test_line_semantics.sh to pass the info about DWARF requirement since these tests failed when perf is built without DWARF. Use the check for presence of DWARF with "perf check feature" and append the hint message based on the result. With the change: ## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY :: 11 failures found :: Some of the tests need DWARF to run Reviewed-by: Kajol Jain Signed-off-by: Athira Rajeev Cc: Adrian Hunter Cc: Disha Goel Cc: Ian Rogers Cc: Jiri Olsa Cc: Madhavan Srinivasan Cc: Michael Petlan Cc: Namhyung Kim Cc: Veronika Molnarova Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20241206135254.35727-1-atrajeev@linux.vnet.ibm.com [ Minor edits changing "dwarf" to "DWARF" as its an acronym ] Signed-off-by: Arnaldo Carvalho de Melo

perf testsuite: Add common output checking helper

2024-08-28T21:07:21+00:00

As a form of validation, it is a common practice to check the outputs of commands whether they contain expected patterns or match a certain regular expression. This output checking helper is designed to allow checking stderr output of perf commands for unexpected messages, while ignoring messages that are known to be harmless, e.g.: "Lowering default frequency rate to \d+\." "\d+ out of order events recorded." etc. Signed-off-by: Veronika Molnarova Cc: Athira Rajeev Cc: Ian Rogers Cc: Masami Hiramatsu Cc: Namhyung Kim Link: https://lore.kernel.org/r/20240702110849.31904-10-vmolnaro@redhat.com Signed-off-by: Michael Petlan Signed-off-by: Arnaldo Carvalho de Melo

perf testsuite: Add common output checking helpers

2024-02-16T19:49:36+00:00

As a form of validation, it is a common practice to check the outputs of commands whether they contain expected patterns or match a certain regex. Add helpers for verifying that all regexes are found in the output, that all lines match any pattern from a set and that a certain expression is not present in the output. In verbose mode these helpers log mismatches for easier failure investigation.
