mac80211_hwsim is a simulated test environment that allows significant
parts of WLAN implementation in both the Linux kernel (cfg80211 and
mac80211) and hostap.git (wpa_supplicant and hostapd) to be tested
without having to use actual WLAN hardware.
hostap.git includes a test framework with more than 2000 test cases
covering large portions of the available WLAN functionality (hitting
over 85% code coverage for wpa_supplicant and hostapd). You can find
that from the tests/hwsim directory. There's also information about this
on the server I use to run the tests after each commit:
