[PATCH v2 16/17] tests/remote: add test_example.py

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
