This is simple example how to write
simple test case.
modprobe mac80211_hwsim radios=4
run example:
./run-tests.py -d hwsim0 -r hwsim1 -t example
run example with monitors:
./run-tests.py -d hwsim0 -r hwsim1 -t example -m all -m hwsim2
run example with trace record:
./run-tests.py -d hwsim0 -r hwsim1 -t example -T
run example with trace and perf:
./run-tests.py -d hwsim0 -r hwsim1 -t example -T -P
restart hw before test case run:
./run-tests.py -d hwsim0 -r hwsim1 -t example -R
run example verbose
./run-tests.py -d hwsim0 -r hwsim1 -t example -v
For perf/trace you need to write own hw specyfic scripts:
trace_start.sh, trace_stop.sh
perf_start.sh, perf_stop.sh
In any case you will find logs in logs/current/ directory.
