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'.
Many tests force a reauth after the initial connection. When the tests
were written there was no way of ensuring the reauth completed except
waiting (IWD.wait()). Now we can wait for hostapd events in the tests,
which is faster and more reliable than busy waiting.
Don't use del wd to dereference the IWD instance at the end of the function
where it has been defined in the first place as at this point wd is about
to have its reference count decreased anyway (the variable's scope is
ending) so it's pointless (but didn't hurt).
Relying on the __del__ destructor to kill the IWD process in those tests
it has been started in the constructor is a bit of a hack in the first
place, because the destructor is called on garbage collection and even
through CPython does this on the refcount reaching 0, this is not
documented and there's no guideline on when it should happen or if it
should happen at all. So it could be argued that we should keep the del
wd statemenets to be able to easily replace all of them with a call to a
new method. But most of them are not placed so that they're guaranteed
to happen on test success or failure. It would probably be easier to do
this and other housekeeping in a base class and make the tests its
subclasses. Also some of these tests don't really need to launch iwd
themselves, since IWD now tracks changes in the known network files I
think IWD only really needs to be killed between tests when main.conf
changes.
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).
list_devices() was updated to take an integer rather than a bool
for the wait_to_appear argument. This updates any tests that
explicily passed True/False as the argument to list_devices.
1) Removed duplicated entries form .conf
2) Refactored to start catching the exceptions and properly
dispose an instance of iwd
3) Switched to list_devices with wait option
