This test occationally fails due to no hwsim rules. Basically we
were just expecting iwd to connect to one of 3 access points but
the ranking was equal, so it chose the first in the scan list.
Now a signal strength is assigned to each AP to steer IWD into
connecting to the expected AP.
Slower systems may not be able to make some timeouts that tests
mandated. All timeouts were increased significantly to allow tests
to pass on slow systems.
The tests basically remained the same with a few minor changes.
The wiphy_map and in turn hostapd_map are no longer used. This
was already partially converted a long time ago when the 'config'
parameter was added to HostapdCLI. This patch fully converts all
autotests to use 'config' rather than looking up by interface.
Some test scripts were named 'test.py' which was fine before but
the new rewrite actually loads each python test as a module. The
name 'test' is too ambiguous and causes issues due to a native
python module with the same name. All of these files were
renamed to 'connection_test.py'.
This removes all the duplicated code where the interfaces are iterated
and the radio/hostapd instances are created. Instead the two new APIs
are used to get each instance, e.g.:
hapd = HostapdCLI(config='ssid.conf')
radio = hwsim.get_radio('radX')
In the tests that only want to iterate over the hostapd interfaces,
simplify the pattern of walking through the whole wiphy_map tree by
instead using the hostapd_map variable which is already filtered to only
contain hostapd interfaces.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
