Provide task-analyzer test cases for all possible arguments and a subset of possible
combinations.
12 Tests in total.
test_basic:
- cmd:"perf script report task-analyzer"
- Fundamental test of script without arguments.
- Check for standard output.
test_ns_rename:
- cmd:"perf script report task-analyzer --ns --rename-comms-by-tids 0:random"
- Standard task with timestamps in nanoseconds and comm renamed.
- Check for standard output.
test_ms_filtertasks_highlight:
- cmd:"perf script report task-analyzer --ms --filter-tasks perf --highlight-tasks perf"
- Standard task with timestamps in milliseconds, task filtered out and highlighted.
- Check for standard output.
test_extended_times_timelimit_limittasks:
- cmd "perf script report task-analyzer --extended-times --time-limit :99999"
- Standard task with additional schedule out/in info and timlimit active at 99999.
- Check for extended table output.
test_summary:
- cmd:"perf script report task-analyzer --summary"
- Standard task with additional summary output.
- Check for summary print.
test_summary_extended:
- cmd:"perf script report task-analyzer --summary-extended"
- Standard task with summary and additional schedule in/out info.
- Chceck for extended table print.
test_summaryonly:
- cmd:"perf script report task-analyzer --summary-only"
- Only summary should be printed.
- Check for summary print.
test_extended_times_summary_ns:
- cmd:"perf script report task-analyzer --extended-times --summary --ns"
- Standard task with extended schedule in/out information and summary in ns.
- Check for extended table and summary.
test_csv:
- cmd:"perf script report task-analyzer --csv csv"
- Print standard task to csv file in csv format.
- Check for csv format.
test_csv_extended_times:
- cmd:"perf script report task-analyzer --csv csv --extended-times"
- Print standard task to csv file in csv format with additional schedule in/out
information.
- Check for additional information and csv format.
test_csvsummary:
- cmd:"perf script report task-analyzer --csv-summary csvsummary"
