[Linux-kselftest-mirror] [PATCH v2] selftest: support run subset of selftests when running installed selftests

by Zong Li

Simply use the first argument to specify the subset of selftests. Use comma notation to separate multiple tests. (e.g. ./run_kselftest.sh size,timers,...) Default behaviour is running all selftests installed. Each selftest be defined as function that we can run one of selftests. The function name has underline as prefix to avoid confilct with built-in command of shell. (e.g. The exec is built-in command of shell) Replace the hyphen with underline for cpu-hotplug and memory-hotplug. Not all shell can use hyphen in function name, like sh, ash and so on.

[Linux-kselftest-mirror] [PATCH] selftests: Fix loss of test output in run_kselftests.sh

by Michael Ellerman

Commit fbcab13d2e25 ("selftests: silence test output by default") changed the run_tests logic as well as the logic to generate run_kselftests.sh to redirect test output away from the console. As discussed on the list and at kernel summit, this is not a desirable default as it means in order to debug a failure the console output is not sufficient, you also need access to the test machine to get the full test logs. Additionally it's impolite to write directly to /tmp/$TEST_NAME on shared systems. The change to the run_tests logic was reverted in commit a323335e62cc ("selftests: lib.mk: print individual test results to console by default"), and instead a summary option was added so that quiet output could be requested. However the change to run_kselftests.sh was left as-is. This commit applies the same logic to the run_kselftests.sh code, ie. the script now takes a "--summary" option which suppresses the output, but shows all output by default. Additionally instead of writing to /tmp/$TEST_NAME the output is redirected to the directory where the generated test script is located.
