940916 - [Marionette] Marionette exception handler

Status: RESOLVED DUPLICATE of bug 960436

(Remote Protocol :: Marionette, defect)

Description

[Walter Chen[:ypwalter][:wachen]]

Currently, if there is an exception, marionette client will catch it. Is it possible to have something that provides customized exceptional handler instead of being caught right away?

There's quite a bit of exception handling in the client. Can you explain this problem and your use case in more detail?

Hi Malini,
We are doing long-term test run, for example, run for 10~20 hours without restart or stuck.
There's a couple way to detect, one is to monitor if the test run starts to have consequent fails of time out, for example 5 to 10 times.
In order to get this result, can we register and listen to fail cases, so that we can force to stop and collect entire running time.

If I understand this correctly, it seems reasonable to allow a test runner to register a function that (during the run_tests call here http://mxr.mozilla.org/mozilla-central/source/testing/marionette/client/marionette/runtests.py#527) will be run after each test is run and it can control whether or not we continue to run tests.

Can this wait for https://bugzilla.mozilla.org/show_bug.cgi?id=925398 to land? ETA a week or so. I ask this because this change will be easy to implement when this lands, but if it's needed right now, I can get a patch going for you relatively soon.

Thanks, that's exactly what we need; will wait til it finished.
