1st. install required packages

sudo apt-get install build-essential git libpcap-dev libsqlite3-dev binutils-dev libnl-3-dev libnl-genl-3-dev libnl-route-3-dev libssl-dev libiberty-dev libdbus-1-dev iw bridge-utils python-pyrad python-crypto tshark python-netifaces binutils-dev libsqlite3-dev libpcap-dev libxml2-dev libcurl4-openssl-dev

2nd. build binaries

#!/bin/bash

pushd ./wpa_supplicant
cp ../tests/hwsim/example-wpa_supplicant.config .config
make clean
make
popd

pushd ./hostapd
cp ../tests/hwsim/example-hostapd.config .config
make clean
make hostapd hostapd_cli hlr_auc_gw
popd

pushd ./wlantest
make clean
make
popd


pushd ./tests/hwsim
./build.sh
popd

3rd. Install a recent wireless kernel components (mac80211_hwsim, mac80211, cfg80211)
wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.xz
tar xJf backports-4.4.2-1.tar.xz
cd backports-4.4.2-1

make defconfig-hwsim

make

sudo make install

4th. Update based iw on custom iw.git build

wget https://www.kernel.org/pub/software/network/iw/iw-3.17.tar.gz

tar xf iw-3.17.tar.gz

cd iw-3.17

make

sudo mv /sbin/iw{,-distro}

sudo cp iw /sbin/iw

5th. Update wireless-regdb

wget http://kernel.org/pub/software/network/wireless-regdb/wireless-regdb-2018.05.31.tar.xz

tar xJf wireless-regdb-2018.05.31.tar.xz

sudo mv /lib/crda/regulatory.bin{,-distro}

sudo cp wireless-regdb-2018.05.31/regulatory.bin /lib/crda/regulatory.bin

# following command can be used to verify that the new version is trusted

regdbdump /lib/crda/regulatory.bin

6th start running test cases
cd tests/hwsim

# load mac80211_hwsim and start test software

./start.sh

# run a single test case ap_open

sudo ./run-tests.py ap_open

This should print out following style results:

DEV: wlan0: 02:00:00:00:00:00

DEV: wlan1: 02:00:00:00:01:00

DEV: wlan2: 02:00:00:00:02:00

APDEV: wlan3

APDEV: wlan4

START ap_open 1/1

Test: AP with open mode (no security) configuration

Starting AP wlan3

Connect STA wlan0 to AP

PASS ap_open 0.175895 2015-01-17 20:12:07.486006

passed all 1 test case(s)

(If that "PASS ap_open" line does not show up, something unexpected has

happened and the setup is not in working condition.)

# to stop test software and unload mac80211_hwsim

./stop.sh

To run all available test cases (about thousand or so), you can run following:

./run-all.sh

For mesh group test

sudo ./run-tests.py -f wpas_mesh

For SAE group test
sudo ./run-tests.py -f sae

For single test

sudo ./run-tests.py  wpas_mesh_open_ht40

# run normal test cases under valgrind

./run-all.sh valgrind

# run normal test cases with Linux tracing

./run-all.sh trace

Trouble shooting

sudo rfkill unblock wifi; sudo rfkill unblock all

systemctl mask systemd-rfkill.service

sudo rmmod iwldvm

sudo rmmod iwlwifi
