Subject: [PATCHv5 kselftest next] selftests/run_kselftest.sh: make each test individually selectable
Currently, after generating run_kselftest.sh, there is no way to choose
which test we could run. All the tests are listed together and we have
to run all every time. This patch enhanced the run_kselftest.sh to make
the tests individually selectable. e.g.
$ ./run_kselftest.sh -t "bpf size timers"
Before the patch:
================
$ cat run_kselftest.sh
\#!/bin/sh
BASE_DIR=$(realpath $(dirname $0))
cd $BASE_DIR
. ./kselftest/runner.sh
ROOT=$PWD
if [ "$1" = "--summary" ]; then
logfile=$BASE_DIR/output.log
cat /dev/null > $logfile
fi
[ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg
cd android
run_many \
"run.sh"
cd $ROOT
...<snip>...
[ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg
cd zram
run_many \
"zram.sh"
cd $ROOT
After the patch:
===============
$ cat run_kselftest.sh
\#!/bin/sh
BASE_DIR=$(realpath $(dirname $0))
. ./kselftest/runner.sh
TESTS="android ...<snip>... filesystems/binderfs ...<snip>... zram"
run_android()
{
[ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg
cd android
run_many \
"run.sh"
cd $ROOT
}
...<snip>...
run_filesystems_binderfs()
{
[ -w /dev/kmsg ] && echo "kselftest: Running tests in filesystems/binderfs" >> /dev/kmsg
cd filesystems/binderfs
run_many \
"binderfs_test"
cd $ROOT
}
...<snip>...
run_zram()
{
[ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg
cd zram
run_many \
"zram.sh"
cd $ROOT
}
usage()
{
cat <<EOF
usage: ${0##*/} OPTS
-s | --summary Only print summary info and put detailed log in output.log
-t | --tests Test name you want to run specifically
-h | --help Show this usage info
EOF
}
while true; do
case "$1" in
-s | --summary ) logfile=$BASE_DIR/output.log; cat /dev/null > $logfile; shift ;;
-t | --tests ) TESTS=$2; shift 2 ;;
-l | --list ) echo $TESTS; exit 0 ;;
-h | --help ) usage; exit 0 ;;
"" ) break;;
* ) usage; exit 1;;
esac
done
cd $BASE_DIR
ROOT=$PWD
for folder in $TESTS; do
folder=$(echo $folder | tr -s '/-' '_')
run_$folder
done

v5:
Forgot to update commit description for the new added -l option
v4:
Add parameter -l to list available tests, suggested by Bird, Tim
v3:
1) rebase the patch to latest code
2) move `tr -s "/-" "_"` in for loop at the end so user could use test
folder name directly. Before the fix, user need to use
./run_kselftest.sh -t 'networking_forwarding'. Now they can just run
./run_kselftest.sh -t 'networking/forwarding' directly.
v2: update document and commit description.
