Every single roaming test had one of two problems with watching the
state change between roaming --> connected. Either the test used
wait_for_object_condition to wait for 'connected' which could allow
other states in between. Or it simply used an assert. The assert
wouldn't allow other state changes, but at the cost of potentially
failing due to IWD not having made it to the 'connected' state yet.
Now we have wait_for_object_change which takes two conditions:
initial (from_str) and expected (to_str). This API will not allow
any other conditions except these, and will wait for the expected
condition before continuing. This allows roaming test to reliably
wait for the roaming --> connected state change.
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.
This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
Updated testFT-SAE-roam to use the TestContext APIs as well as
fixed the failure which was introduced after requiring stricter
AKM logic for SAE networks. The new failure was due to the hostapd
config not including the standard SAE AKM which is actually
required by the spec.
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')
Running autotests with native hardware will not work on tests which
depend on the hwsim python API (since hwsim will not be running).
For these tests, it will now be required that they specify:
needs_hwsim=1
This allows the test to be skipped when running with native hardware
rather than the test failing with a python exception.
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.
This test was copied from testFT-PSK-roam, but for SAE. The test behaves
as follows:
- Connect to SAE network (full authentication)
- Fast transition to another SAE AP
- Fast transition to a PSK/WPA2 AP
